All of your videos are great man. Thank you.

Beautiful. 👍

Thank you very much!

Thank you so much 👍

Really wish I had the equipment to try this. You make it look so good that I want to try

[@MattJasa]

Thank you! 😀

[@joshg6491]

You probably said this before but is there a shop I can buy some of it from?

[@MattJasa]

@@joshg6491 www.mountainglass.com/ does great work. I'm not affiliated so your getting my honest opinion. It's best to buy glass in bulk when it goes on sale 30-40% off. I think they do that to clear out stock for their next order from the manufacture.

I've been using scalloped tubing since the 90's.

[@MattJasa]

Sorry, I meant its new for me. It recently popped up in my suppliers inventory.

[@jessedack1964]

@@MattJasa it's awesome for fume work too... do you do fume-scratch at all?

[@MattJasa]

@@jessedack1964 Nah, I haven't practiced much of fuming. It's definitely a field in-itself, you can do a lot with just fume and clear.

[@jessedack1964]

@@MattJasa the first 1k hrs I worked on the torch were clear and fume. Hmu if you are interested in learning. I got my 1st torch in 1997.

[@mattpfeifer9302]

I'm diggin the upload regularity. So many people only correlate boro with pipes and you're doing quite well at proving boro's versatility and breaking any negative stigmas associated with borosilicate and/or lampworking. Keep it up

[@MattJasa]

That's the plan! Thanks, I'll do my best.

[@colethynne]

How do you keep coming up with so many ideas for videos?? Great job as always, just here for my thumbs up vote !

[@MattJasa]

Hey Cole, thank you! Nature is my muse and I it's tuning fork. (Update: That was reference to the glass tuning fork video.)

This is the first time I've seen frit used on the inside. What a cool way to use it. I never would have thought...Edited to ask, How are your lips safe from the frit while you are blowing into the tube? When I saw you filling the tubes I wondered.

[@MattJasa]

Yea I might have to also do an outside application to see the difference. I usually wipe the ends of the tubes a little bit, It doesn't really stick to the tube unless its wet. Thanks for watching, have a great day! =)

[@iamstrangeiam]

@@MattJasa Matt, be aware that although your blowtube looks clean, there certainly is silica lining it. But since we don't usually suck through it you're fine, just something to be aware of on your journey. Any blowtube I use for frit gets rinsed out and kiln dried lol

[@jessedack1964]

@@MattJasa I never put frit in thru the blow-tube. Just open the end of your pulled piont and pour in your frit.

[@MattJasa]

@@jessedack1964 Yea I like that method.

Hi brilliant videos helping me get back into lampworking after an I’ll health break. If turning these into baubles to hang would you just turn the holder into a hook or do you need a hole at the top for expansion. Cheers. Hope your good in this worldwide lockdown.

[@MattJasa]

Hey Richard, it is good to leave a hole in them so the inside pressure can equalize with the outside pressure of where its hung. Also you could make a glass hook OR use a Christmas bulb metal cap like a normal Christmas ornament.

[@llgs]

Matt Jasa brill thanks for that. Be glad when the lockdown finally ends. Stay safe and well and keep hot glassing. ;)

[@timcapell]

I’ve only ever worked on soft glass. I own a GTT Cheetah, I assume thats too small of a torch for boro glass? I wonder if they make glass tube in softglass

[@iamstrangeiam]

Cheetah will get boro moving for sure. Any GTT will do fine.

[@MattJasa]

On the contrary TKyron, the GTT Cheetah would be a strong starter torch for boro. It's less about size and more about being an oxy/fuel torch. Without oxygen the flame wouldn't be hot enough to melt boro.

[@joshschneider9766]

Of say they are the equivalent of a redmac, but I'm no expert Boro worker

[@dudders___1684]

I have a gtt bobcat stage 1 and I can melt borosilicate COE 33 glass easily

[@LilDirt12]

Love your voice. And your not condescending. Which is rare these days. Question: I have tried adding colored cane to clear, the clear cracks. Could this be two different mixes of glass or is it due to thickness differences/ cooling temps? And would I avoid that problem if I use this crushed glass instead? Thank you for your time.

[@MattJasa]

Thank you, I try my best. It would be hard to say exactly without seeing you work, but it sounds like thickness and cooling. Do the cracks happen as your laying your lines or after it cools in the kiln? If they happen while you work then the blank might not be warm enough or cooling down to quickly. Larger sections of tubing can be difficult to keep at working temperature. If they happen after an annealing cycle then it could be COE compatibility. A dense sparkly color like Heavy Blue Leprechaun for example might have issues. Lastly crushed glass (frit) is a good way to add color quickly for production work. It has it's own style compared to solid color or cane; lots of texture. It can be used in interesting ways like with scalloped tubing to created Frit-Lined tubes as in this video or layered to produce chromatic effects.

Where do you buy the scalloped tube?

[@MattJasa]

I bought mine from Mountain Glass Arts. www.mountainglass.com/search?keywords=scalloped

@@MattJasa thanks man! Just getting into lamp working. Your videos have been a wealth of knowledge. Are you on IG at all?

[@EscosFishfarm]

instead of dipping the blow-tube in frit use a piece of paper to make a cone funnel my word of advise
