Hello, I'm Matt Jasa. If you are interested in learning about Glass blowing or Lamp working my channel offers a lot of advice on the techniques, tools, and general safety. Make Artistic pieces (animals, marbles, pendants), scientific items, and blown functional glass. Put your mind to it and with practice you can make anything!
Some more specific projects you might find on this channel are Glass Chain Necklaces, Glass Pendants, Marbles, Magnifying Glasses, Glass on Glass Fittings ( GonG ) and Blown Spheres. I also use small explosives from time to time for scientific tests; however these eplosive projects should never be attempted at home, safety is my highest precaution! Never attempt glass blowing without proper ventilation and eye protection.
Check out my videos on setting up your glass blowing torch along with how to adjust for the right flames; such as neutral, oxidizing and reducing flame before you begin. Learn how to cut, clean and prepare your glass for future projects.
Never store your propane in-doors, Always keep propane tanks outside! Propane gas is heavier then air, if a leak occurs it will begin to pool and fill a closed room or basement which can lead to an explosion.
If you have any questions about glass blowing, lamp working, or this video please leave them in the comment section down below. I may not respond immediately as I'm mostly busy in the glass shop but I'll get to it as soon as I can. If I don't respond to your question I might have missed it; please re-comment the question on the relative video.
Please join me in this exciting journey to see what can be done with glass. I create these videos to enrich others in the process; teach them to create their own works, but also for everyone else to enjoy the unique perspective and spectacular show that science/nature can provide.
I put a lot of work and time into each video. Most projects require 1 to 2 hours to complete in the shop and then several more editing the footage while adding voice-over. I've worked on some videos well through the night and into the next morning. So help me bring glass blowing and lamp working to others; please share this video on your social feed, be apart of the awesome journey.

Additional notes: I discussed a "glass giveaway" for the kick off of the channel, however the growth was so slow it never really kicked off. So instead I gave away my knowledge for the next 4 years. Join me now again in 2021 as growth is starting to climb like never before, help me bring glass to the forefront of KZfaq!

You can use this three section blowout technique for your own work. It's great for getting a larger bubble on a smaller torch. Make sure to subscribe and check out my more recent work! This video is currently about 4 years old; things have been improved a lot since then. I've also recently updated the caption as my old microphone left it terribly inaccurate. Thanks for watching!

I usually have trouble when I start getting to the middle, as I'm trying to condense the glass and thicken it before I blow it to the size of the other bubbles it begins to fold over its self or droup completely, and idea what I'm doing wrong and how to get everything even and not folding over?

@MattJasa 3 жыл бұрын

@@cwayne2833 Hey Chase, you might be able to blow out the middle section without condensing it down. As the middle section shrinks smaller it becomes less stable. Working a little colder until its halfway blown out might help keep the stability also. I hope this helps, best of luck on your glass journey!

I've been trying to do this for weeks man but with smaller tubing, 12mm, in an attempt to blow an ice chamber.. if u could do a video like this but with small3r 12mm tubing it would really really make my entire month as I've just about given up as I keep trying that bit too much bigger and bigger and eventually pop it 😭 P.s I'm only a couple months Inti glass blowing and only using a map has bernzomatic ts800 for the time being... what torch would you subtest for under 700 dollars Aus?

@MattJasa Жыл бұрын

I don't think you can get such a large bubble from such a small tube. You can melt the tube back to thicken the walls before you blow it out, but it will only go so large before thinning too much and popping. So 12mm might blow out to around 30mm. For 700 Aus you might afford the Bobcat from GTT. It's dual gas so you'll need propane & oxygen. It won't take MAPP gas but will do natural gas.

@MattJasa Жыл бұрын

@@anonymousasylum6561 Thats ok, I like to help. I have used both, they function about the same. The Alpha might be slightly larger in flame size, it also works well on oxygen concentrators where my Bobcat is limited to 8lpm on a 10lmp concentrator. Both can use tanked oxygen. Both torches can tilt, however the Bobcat needs a simple wrench while the Alpha has a tool-free lever. The Alpha can swivel which isn't important unless you're on a lathe. The Bobcat is about 20% cheaper in price. That's everything I can think of, I hope this helps.

@MattJasa 3 жыл бұрын

If you heat up any cracks directly they may continue to split and become worse. You can kiln the item and attack the crack at working temperature to keep it from splitting. The crack might also open up into a hole instead of sealing closed. So it's a bit tricky, but worth an attempt.

I mean I love Glassblowing but for "science" the starting music does not fit. I recon you like the music & therefore choose it. Also in the part where you are talking up to the middle, the music fiights against your explanations. If you really want to explain something, you dont need the coolness or anyting else. How you do the glassworks is the main thing and people will come for that. If on the other hand you want emphasize the coolness, the explanations are of course superficial.

@MattJasa 5 жыл бұрын

Hey Christian, yea I know the music sometimes is a bit annoying but for a lot of people I think it gives them that 'movie' kind of vibe . I've been turning it down more in my latest videos and just turning it back up when I'm done talking. Lately I've been using a 2nd camera to get more detail in the process. If you love science I recommend you try glassblowing, the two just go so well hand in hand.

Bro.... please don't take this the wrong way aa I only want to help. I debated on whether I should say anything but the way I see it only your real friends will tell you that your fly is down if you have food in your beard ....things like that. Well I just want to make sure you know the word is "axis" not "access". I know it may sound petty but it's little things like that that can take away credibility. I know very little about blowing glass and you obviously do know what you're doing but you use the word fairly often and it distracts me from paying attention to what you're doing. I'm sitting there wondering "does he know which word he's using?" "Does he maybe know how to spell it ...he's just says it weird or does he really think it's the word access?" So giving you the benefit of the doubt that you know what you're talking about and in light of the fact you speak of this concept regularly, maybe throw in some variations of it like concentric, eccentric, on center, off center, on axis, off axis.... just some ideas. I'm a journeyman machinist of 22 years and working with mills and lathes , I hear that word being said incorrectly often and it's become one of my pet peeves. So it's nothing personal and again just trying to help. Other than that sir, I like your videos. Keep doing what you doing and thanks for doing it! Feel free to delete this comment if you are able to. I'm not trying to put you on blast for everyone to have a laugh... I just think somebody oughtta tell a brother his shoe is untied before he trips on it and breaks a bunch of pretty glass creations. ;) If you feel like I helped at all and want to thank me, I could use a nice chillum. Something simple that fits in a cigarette pack but has a bowl big enough for 4 or 5 good puffs. Have an awesome day sir! I want to learn your craft. Looks like fun that won't break the bank.

@MattJasa 6 жыл бұрын

Thanks for taking time to point that out. Sometimes I do pronounce words oddly, it can only be fixed once you or someone else recognizes your doing it. Your right I did mean axis as in 'to have everything in correct alignment.' But if you are interested in lampworking keep watching the videos then jump into it. With your experience you might have most of the equipment and knowledge already. The lampworking torches use propane instead of acetylene, they tend to burn colder but in a larger area, they're great to keep from boiling the glass.

@andydufresne8113 6 жыл бұрын

Matt Jasa Right on! So, to clarify, it's only "glass blowing" is you use an oxy/acetylene mix and it's "lampworking" if you use propane? Is that because you're inducing air to the combustible gas that "blowing" comes into play? Or is it that glass blowing is more slang and lampworking is the proper terminology? I know, I ask a lot of questions.... it's so I don't sound like a Noob when I speak about it later. ;) It definitely looks like it's a lot of fun. I'm getting more creative in my old age, I guess. I was never really interested in making anything that wouldn't do a wheelie when I was younger. Brrrraaaaap!

@MattJasa 6 жыл бұрын

Good question, Generally I use 'Glassblowing' more as an umbrella term but the traditional method is to use a large furnace. Using a large metal pole (punty) they gather and heat the glass through a hole in the furnace. It was used a lot for larger vessels and goblets. Then I beleive Lampworking came in later were they would use an oil lamp to melt fine strands of glass to decorate the goblets even more. Thats were it gets its name lampworking, which now we use "Burners". Most people call them Torches, but a Torch might indicate the fuel source is built-in so it wouldn't be allowed on a plane, However a burner carries no fuel, only burns it, so it can travel carry-on.

@MattJasa 6 жыл бұрын

Oh and the reason I mentioned the oxy/propane vs oxy/acetylene was just me assuming you had an acetylene burner already being a machinist. Also Lathes are super popular in lampworking, from scientific work to furnace sized pieces.

@andydufresne8113 6 жыл бұрын

Matt Jasa yah, that would've been true if we were 30yrs ago on the machinist time line. Welding used to be a requirement to be a Journeyman Machinist. That was before the tech boom. Nowadays, everything in fabrication is more specialized. I can cut parts on the old school (hand crank) mills and lathes quite well but I was more focused on CNC (Computer Numerical Control) machines. Writing programs and building setups for workholding. Here in the SF Bay Area, the bulk of machining is semiconductor and aerospace which inherently require near flawless precision. (That's why 22 years was enough stress for me) so machinists cut metal. Welders pretty much just weld. We work in tandem on a lot of jobs like building aluminim vacuum chambers but that's some serious specialty welding that takes a hell of a lot of technical skills that have to stay honed to maintain quality. I compare it to skateboarding. If you take a month off, you will need to skate another 2 months before you are back where you were. Sorry for the long winded response. I'm all about details...lol
