The Art of Glassblowing: A Beginner's Experience

As I stood at my workbench, surrounded by the tools of the trade, I couldn't help but feel a sense of excitement and trepidation. My friend had handed me a glass tubing, and with it, a chance to learn the art of glassblowing. I had always been fascinated by this ancient craft, and now, I was about to put my hands on it.

So, I heated up the ends of the glass tubing using a torch, carefully controlling the temperature to avoid overheating it. As I cut it, I made sure not to spray water on it, as that would cause the glass to become brittle and prone to cracking. After cutting, I let the excess glass drop into a waiting container, careful not to touch any of the hot glass. This was my first attempt at bending glass, and I was determined to get it right.

As I worked, I couldn't help but think about the similarities between glassblowing and working with acrylic or PETG. The principles were similar, but the results were worlds apart. Acrylic and PETG are easy to work with, as they can be trimmed and reshaped easily, whereas glass is much more finicky. If you mess up, you have to start over from scratch.

Despite this, I was determined to master the art of glassblowing. I carefully dipped the end of the tubing into a container of molten glass, using a specialized tool to shape it into the desired form. As I worked, I couldn't help but feel a sense of satisfaction at how well the glass was behaving. It was like magic, transforming from a molten liquid into a beautiful, delicate tube.

But as I delved deeper into the world of glassblowing, I realized that there were some tricks to it. For one, it's essential to have a good understanding of the heat and temperature required to work with glass. If you don't get this right, you risk overheating the glass or underheating it, which can result in a range of problems from misshapen tubes to complete failures.

One of the most critical tools for any glassblower is the scoring device. This small tool allows you to carefully score and break the glass without shattering it completely. It's finicky to use, but with practice, you can master its techniques and create beautiful, intricate designs.

As I continued to work on my project, I couldn't help but think about the challenges that came with working with glass. For one, it's extremely hot, and even a moment of carelessness can result in injury. It's essential to wear protective gear at all times when handling hot glass, including gloves and safety glasses.

Despite these challenges, I was determined to push on. With each attempt, I refined my technique and learned new skills. And as I looked at the finished product, I couldn't help but feel a sense of pride and accomplishment. This was my first perfect 90-degree bend, achieved with just one try.

One thing that struck me as I worked was how clear and transparent the glass tubing was becoming. It's like magic, watching the molten glass take shape before your eyes. The clarity of this glass is exceptional, and it's truly a testament to the skill and expertise of the glassblower.

As I finished my project, I couldn't help but feel a sense of excitement for what lay ahead. With each new attempt, I was learning more about the art of glassblowing and pushing myself to new heights. And as I looked at the finished product, I knew that this was just the beginning of an incredible journey.

What's Next?

So, what's next? As a beginner, I'm eager to take on new challenges and push my skills further. I'd love to learn more about the scoring device and how it can be used to create intricate designs. I'm also interested in exploring different types of glass tubing and learning how to work with them.

I'd also love to hear from you, our readers! Do you have any experience with glassblowing? Do you have any tips or tricks to share? Let us know in the comments below! Sound off and let's get the conversation started.

"WEBVTTKind: captionsLanguage: enall right it's been a while since i played with glass tubes and today we're going to just kind of practice some techniques here the last time i did i've only done two glass builds actually in my youtube career i don't remember which ones they were one of them still together over there actually but the other one i forget what it was oh the d frame built that's right and i remember people yelling at me that i was doing it wrong and i thought to myself well i scored the glass i broke the glass i filed the glass i put it in the system and it's holding water so what did i do wrong well we were watching some glassblowing videos today and we decided hey let's try this ourself so today we're going to show you guys how to properly score and cut glass the tools you need to do it uh if you want to do straight pieces and then we're going to play around with some heat yes i know map gas isn't exactly the right type of fuel to use this because it doesn't burn as hot as oxyacetylene however this is uh what i've got and i was i was able to make a very phallic looking piece of glass before this video so bite me nzxt's starter pc series now starts at 699 dollars and

below all right so the glass that we're using here you can buy from just about any like major water cooling supplier um it is borsilicate is the type of glass actually if you're wondering there's different types of glass obviously i guess boar silicate would be much more of like a laboratory grade i guess the same kind of stuff they make like beakers and whatever they're called beakers okay i was thinking that was a character on sesame street but that's meeker right or muppet babies wow okay that went weird so first things first they come in these links like this is an uncut piece right here they're not very long so most of the time you're not gonna be able to make a very long run at least not with the pieces that i've got you probably get them much longer the chances i'm being damaged in transit is gonna be even higher they're usually wrapped pretty good if they come like this usually there's three or four of them in a bubble wrap and then each one of the tubes themselves has a lot of tissue paper wrapped around it this is 12 millimeter diameter here you got 12 13 and i believe 16 has kind of made its way around now so what we're going to show you first of all is how to get the length to where you want it so what you need to do that is going to be a pretty there's different types of scoring tools out there i've tried the ones that look like clamp pipe pipe clamps where you turn it turn it turn it it uses basically a diamond blade remember diamond cuts glass pretty easily but i didn't like that one it just i found that it spiraled and it kind of walked so as i was turning it it didn't stay on exactly square because the blade would sort of bind and by doing that it would just sort of walk and make a spiral which isn't what we want so what we are going to do here now is get my marker because i forgot to get my sharpie so let's just say for instance uh this is the piece we want to cut and we go okay we need it to be you know right there we need our scoring tool i'll put a link to this on amazon from amazon i got this years ago but it's pretty basics it's a chain that's got those little blades like i said but only a lot of them that go around and clamp around the glass and then this will lock down on it the other thing you're going to need is some gloves and you're going to need a mask because what this can create every time you snap it is glass dust really fine particles that you can't even necessarily see smell or feel but can still make their way into your lungs that's bad so you want to protect your breather with a some sort of like a a 95 yeah so something good for particulates like that and why was it coming over here oh gloves that's right these aren't matching gloves and they're two right hands all right so we got our gloves on here that are going to protect us from getting cut i also need eye protection because when you go to score and snap it you don't want any bits to comply in your face if you do it right it should not be a very violent snap we have a spray bottle with water you could use spit for this part but i prefer to just use a spray bottle of water because it's much nicer now the nice thing about this tool is the fact that you can adjust you know how big of a diameter you can deal with hold that like that you can hear it sort of scoring the glass this is a very feel based thing the intervals at which those links are are going to make it either too loose or too tight so if you clamp it all the way down you're going to break the glass you want to hold it and start applying slight amount of pressure until as you turn it you hear that crunching sound now if i loosen this we take a look at it you can see i've scored the glass all the way around now what we can do we just take a little bit of water this is where science comes in and magic happens the water makes it easy to just snap it like that so now what you get are these really that looks broken but it's not it's just the water you get a really clean break right that's really really clean but it's sharp listen my glove see it's sharp see what i'm doing at the table that's going to cut your o-rings obviously and it's weak now because we just scored it there is a portion of which the glass becomes weak right there so that's where this guy comes in now one of the things that we can do that i like to do anyway is i like to always take my stuff i know the people out there that do glasswork or looking at me right now going what are you doing you can't put that sort of lateral tension on there it's gonna break it you're right but that's why i'm just holding it like barely clicked in there so it turns now you're going to notice something that happens here as you start to heat it watch when i heat down here the flame stays blue but the hotter it gets it turns orange see that so that's where you start to know you're getting good temperature on the glass battery's dying now what i'm going to do is i'm going to take this file and just hold it against the edge as it's turning take this little uh 2000 grit sandpaper see how hot that is don't touch now i use this guy to help cool it down without cooling it down too quickly but now look at this see we can't make any marks on the table now because we've gotten rid of all those sharp edges and i just felt a little bit of that heat through the glove the glass will hang on to the heat up for a bit that's what this is for it gets cool again pretty fast it's a little dirty right now because of the gloves but it gets cool again pretty fast once you uh get it wet now we can just sort of clean the glass so i want to talk about the the proper way of breaking the glass after you've scored it one the score needs to be all the way around it has to be all the way around um if you don't break it all the way around you'll end up with something sort of like this this is a really bad score and this is a piece i saved this is a years old piece of glass because this is what i was learning and i would get the length marked because what i would do is i would use petg or acrylic to get all my bends done in the system then those are just used as templates to make my glass so you can see right here i did not have a good score it didn't go through the surface of the glass far enough so when i broke it it was extremely jagged that's a throwaway piece and you can see the one that we just did okay this is a machine cut this is how the machine cut it because when they cut the stuff in the factory they've got a special diamond blade with water and all sorts of stuff that cuts this perfectly clean and even bevels the edge slightly this is the one i did by hand sure it's got what looks like a little bit more jaggedness to it i think that's down inside the glass slightly which is why we heated it like we did but it's smooth and it's going to slide into our fitting just right but the way that see here's a score that i did right here as a practice right this is not a good score you can't even feel this with your fingernail in fact i'll try and break that right now to show you how bad it is but when you go to score it you want to grab it with your thumbs and your fingers like this about an inch away or about 25 millimeters away on either side and you want to apply pressure like that so you want to take these fingers and sort of push it against your thumbs and pull away that's how you get a nice really nice good score now let me put my mask back on real quick and show you guys what happens if i try to crack that which is a terrible score so if we look at this score you can see a little bit of the glass dust because i went i pushed real hard right there pressure wise but then look as i go around see how that doesn't really have much of a score so i'll show you right now how bad the break would be that actually went really well when you try and screw up and you can't but you want to show people you're professional and you only screw up that's jade's two cents now when it comes to putting it on to you know the fitting and stuff the edge is nice and rounded now so you're not going to cut this o-ring look at these o-rings these are tiny guys right so you take this guy wet the end of the glass a little bit so you have a little bit of lubrication put on the o-ring and slide on your collar kind of twist as you're going there that's in there and there you go you've got your glass tubing so here's something people tend to forget though when it comes to glass obviously you can't just sit there and squeeze on it like crazy you're gonna have to find the right amount of tension to where it obviously doesn't leak but then at the same time it's all the way down in there and it seals completely so i'm just going to kind of twist it as i work it in there see how it slid down in there now the collar is where it's compressing that o-ring against the cir the outside diameter of the glass and against the ins the outside of the inside bore of the compression fitting so you're just going to kind of go into it won't go no more there you go now the clarity of glass versus like ptg acrylic look at that there's just nothing like that it makes me want to do another glass build but one of the things that's always kept me from doing glass builds is the fact that you have to use fittings for all the bends that's not inherently a problem unless you just want nice bent tubes and you don't want to spend a crap ton of money for all those extra fittings so that's why today now that i've showed you what i already know we're gonna try and learn something together disclaimer i am not an expert at working with glass i am you they're i can't even talk i am wearing the wrong kind of footwear for this as i'm wearing open-toed shoes same we all are i think this next part you do as you will and not as i say because i'm just experimenting because i looked at it this way if you heat plastic to bend it you just heat glass more and bend it right swim bj's two cents if there wasn't some level of jank i like to use my drill like i showed you guys as a home makeshift lathe because i don't have a lathe so i've chucked it up into my drill ah i know it will bend because i've already done it it's not a very good bend but it's my first how many of you guys had perfect first bends not many of you i'm sure so what we're kind of playing with here is the bending radius to keep it from crushing on itself because i don't have a mandrel and it's not a long enough piece for me to be able to blow into because you know when you blow in the glass that keeps it from collapsing on itself i don't think i could cap these off because then i figure if the air was in there the air would probably still compress enough to where it would it would collapse so what i did here was i just heated up the glass real real hot real hot in one spot so the weight would make it bend on itself but the problem is as you can see it flattens out the outside and it crimps the inside sure you'd still get water flow through here and it'd be perfectly fine it's just aesthetically not pleasing so that's why i want to see if i heat up a little bit wider area will we be able to get it to bend more of a smooth radius so let's talk about the temperature here real quick like i showed you earlier when i'm hitting it with the torch you see the flame continues to be blue all the way across see that once that area starts to get hot it starts to turn a very bright orange if you've ever watched a glass blowing video you've seen that the flames are very orange now they're dealing with much hotter gases than i'm dealing with here so the map gas will take a little bit longer if you're a gear head or somebody at home that has a shop and you have an oxy acetylene torch in the garage yeah light bulb because that's much hotter gas and it will work really well i'm only rotating it so that we're applying the heat evenly around the glass not getting a hot spot on one side but then once it starts to droop then i'm going to stop spinning it otherwise it'll just by god i think my second one was the one that was only my second time ever trying to bend glass it's just like acrylic it just takes a lot longer i'll be dipped smart man said that once all right so now i'm just gonna cool this down with the little vac vacuum blower here thingy it's not a vacuum it's a blower so i don't know why it's a vacuum blower but whatever it's vacuuming on that side so like i said after you've heated the ends when you cut it and you don't want to spray water on it don't spray water on it either after this point um i've got to say for that being my first attempt and that being my second attempt i think i adjusted pretty quickly that did not crush on itself whatsoever so no mandrel was even needed that's the first thing that surprised me second of all the clarity of this i think i need to do another class build in the future because i i would not try a double bend i mean maybe i would if i had plenty frame it yeah yeah my first second technically my first perfect 90 degree bend that was eyeballed too look at that so yeah now what i would do is uh and this is the part that would be scary because i would bend it first and then i would chop the ends to be the length i need them to be the thing that sucks about glass versus like acrylic or petg is you can easily trim plastic and acrylic notice i said acrylics not plastic because it's not if you screw up and you score it wrong and you snap it wrong then that bend is wrong because you have to do the piece again minimum distance of being able to crack the tube is something to talk about so if you wanted to trim like an inch off that's not going to happen you're not going to get the leverage you need on it let's say that blemish right there that's the mark we wanted to cut it so let's say that was the mark you're you're not gonna be able to score that because you can't get and i've tried i've tried going okay what if i wrap it in a cloth and then i take pliers no the grip the amount of strength it takes to clamp the pliers onto it it will just break pieces off and it won't work i've got pieces that look like that so i say if it's longer than being able to get at least two fingers on it like that like if it's shorter i mean then you you're not gonna be able to break it cleanly that's when you would need to have a proper glass saw and then you could chop it you know and and all that stuff so so you want to be extremely precise and like i said what i always do and i don't have any scraps hanging around to show you guys do i uh yeah i do look at the clarity difference between these two with the light shining through it it just refracts all perfectly in there this video needs some j effect to it not just a tutorial sounding all smart because we need to do something stupid dude it it's just like acrylic only it's glass like the the way it behaves and everything like i would swear that that's acrylic right now that's cool looking i made a spiral i'm a glass blower now no okay i don't send your hate mail i'm aware of how bad this is but i'm really just showing how like nobody touched this it's really it's really hot okay nobody sets that it's hot dangerous danger although it's like impossible to see against the warranty the acrylic behaves in very much the same way only much sooner oh it's molten it's molten okay that's where we stop so we like to make videos when we do things time to get out of here so what i need you guys to do is sound off down below if you guys want me to do a build utilizing you utilizing glass tubing again but this time it's burning your glove yeah it's still really hot guys let's remind you to sound off and tell me if you want me to do a glass tubing build again um it's a possibility of me burning myself i had clearly put a hole in my glove right now i was like what's that smell oh that's me anyway expert glassblowers and stuff comment if there's any particular tool or anything i could get to make this any sort of you know any easier on me the scoring device works really well it's just finicky to use but as you can see i did a pretty good bend without even uh having to try so well i tried twice thanks for watching guys trying to come up with some creative content right now in this tech lull so we appreciate you guys watching and as always we'll see you in the next one hey let's heat the bottleall right it's been a while since i played with glass tubes and today we're going to just kind of practice some techniques

bends not many of you i'm sure so what we're kind of playing with here is the bending radius to keep it from crushing on itself because i don't have a mandrel and it's not a long enough piece for me to be able to blow into because you know when you blow in the glass that keeps it from collapsing on itself i don't think i could cap these off because then i figure if the air was in there the air would probably still compress enough to where it would it would collapse so what i did here was i just heated up the glass real real hot real hot in one spot so the weight would make it bend on itself but the problem is as you can see it flattens out the outside and it crimps the inside sure you'd still get water flow through here and it'd be perfectly fine it's just aesthetically not pleasing so that's why i want to see if i heat up a little bit wider area will we be able to get it to bend more of a smooth radius so let's talk about the temperature here real quick like i showed you earlier when i'm hitting it with the torch you see the flame continues to be blue all the way across see that once that area starts to get hot it starts to turn a very bright orange if you've ever watched a glass blowing video you've seen that the flames are very orange now they're dealing with much hotter gases than i'm dealing with here so the map gas will take a little bit longer if you're a gear head or somebody at home that has a shop and you have an oxy acetylene torch in the garage yeah light bulb because that's much hotter gas and it will work really well i'm only rotating it so that we're applying the heat evenly around the glass not getting a hot spot on one side but then once it starts to droop then i'm going to stop spinning it otherwise it'll just by god i think my second one was the one that was only my second time ever trying to bend glass it's just like acrylic it just takes a lot longer i'll be dipped smart man said that once all right so now i'm just gonna cool this down with the little vac vacuum blower here thingy it's not a vacuum it's a blower so i don't know why it's a vacuum blower but whatever it's vacuuming on that side so like i said after you've heated the ends when you cut it and you don't want to spray water on it don't spray water on it either after this point um i've got to say for that being my first attempt and that being my second attempt i think i adjusted pretty quickly that did not crush on itself whatsoever so no mandrel was even needed that's the first thing that surprised me second of all the clarity of this i think i need to do another class build in the future because i i would not try a double bend i mean maybe i would if i had plenty frame it yeah yeah my first second technically my first perfect 90 degree bend that was eyeballed too look at that so yeah now what i would do is uh and this is the part that would be scary because i would bend it first and then i would chop the ends to be the length i need them to be the thing that sucks about glass versus like acrylic or petg is you can easily trim plastic and acrylic notice i said acrylics not plastic because it's not if you screw up and you score it wrong and you snap it wrong then that bend is wrong because you have to do the piece again minimum distance of being able to crack the tube is something to talk about so if you wanted to trim like an inch off that's not going to happen you're not going to get the leverage you need on it let's say that blemish right there that's the mark we wanted to cut it so let's say that was the mark you're you're not gonna be able to score that because you can't get and i've tried i've tried going okay what if i wrap it in a cloth and then i take pliers no the grip the amount of strength it takes to clamp the pliers onto it it will just break pieces off and it won't work i've got pieces that look like that so i say if it's longer than being able to get at least two fingers on it like that like if it's shorter i mean then you you're not gonna be able to break it cleanly that's when you would need to have a proper glass saw and then you could chop it you know and and all that stuff so so you want to be extremely precise and like i said what i always do and i don't have any scraps hanging around to show you guys do i uh yeah i do look at the clarity difference between these two with the light shining through it it just refracts all perfectly in there this video needs some j effect to it not just a tutorial sounding all smart because we need to do something stupid dude it it's just like acrylic only it's glass like the the way it behaves and everything like i would swear that that's acrylic right now that's cool looking i made a spiral i'm a glass blower now no okay i don't send your hate mail i'm aware of how bad this is but i'm really just showing how like nobody touched this it's really it's really hot okay nobody sets that it's hot dangerous danger although it's like impossible to see against the warranty the acrylic behaves in very much the same way only much sooner oh it's molten it's molten okay that's where we stop so we like to make videos when we do things time to get out of here so what i need you guys to do is sound off down below if you guys want me to do a build utilizing you utilizing glass tubing again but this time it's burning your glove yeah it's still really hot guys let's remind you to sound off and tell me if you want me to do a glass tubing build again um it's a possibility of me burning myself i had clearly put a hole in my glove right now i was like what's that smell oh that's me anyway expert glassblowers and stuff comment if there's any particular tool or anything i could get to make this any sort of you know any easier on me the scoring device works really well it's just finicky to use but as you can see i did a pretty good bend without even uh having to try so well i tried twice thanks for watching guys trying to come up with some creative content right now in this tech lull so we appreciate you guys watching and as always we'll see you in the next one hey let's heat the bottle\n"
