Can Borosilicate be attached to a MASON JAR?
Can 4mm Borosilicate Glass Blowing Tubing be attached to a MASON jar?
No lampwork experience here.
Just a beginner.
The goal is to experiment with vacuum tube electronics.
A vacuum sealer machine for food can suck down a mason jar lid and create the vacuum in the jar and then the threaded rim is twisted tight.
The mystery is how to attach wires to electrodes inside the vacuum
so I had this idea to place wires inside borosilicate 4mm tubes and pinch them flat around the wire and then melt them and stick them to the flat bottom of the mason jar.
Perhaps the mason jar should be drilled with a tile hole saw first to accept the 4mm tube.
Stumbling the internet and finding glass tubes readily available on AMAZON
and also mapp gas
and other pencil shaped flame torches and lots of YOUTUBE videos
and beginner lamp work books was very inviting to play with this idea.
and then it got technical.......
Coefficient of Expansion.... COE came into the rules.
So ... what is the COE of mason jar glass?
Can it be fused with borosilcate glass?
With a mapp gas torch?
The reason to use the mason jar and be locked into using the mason jar
glass is because the mason jar is designed to be used in the vacuum machine so I can not get away with any other glass options that do not have the twist
lid configuration unless I pick another glass ... and ....that would mean investing in extremely unique vacuum hardware to be used solely with glass blowing.
I have not found any examples of how to set up that work shop.
Is there a glass forum for that kind of glass work?
Perhaps neon signs use vacuum pumps?
