How big can we go on a torch
I'm planning to blow boro tube into vessel but am wondering how big can I blow with a torch ?
What is the maximum tube size and blown vessel size possible with a torch ? I'm planning to buy a big size torch to blow boro soon. It will be connect to oxygen tanks. |
I've seen a 6 inch diameter pitcher blown using 50mm heavy wall tube and a GTT Delta Mag. It was about 9 inches tall. I think there have probably been larger pieces made by someone but I haven't seen them in person.
The ability to do something like that is determined more by your experience than anything else. Can you effectively handle a large piece of heavy molten glass? If so then go for it. By the way a Delta Mag turned up will empty a K tank of oxy in about 15 minutes. |
Depends on the person doing the blowing. There really isn't a limit other than ability.

Yup, it's about managing heat base effectively. The bigger limits are your patience and oxygen supply.

These were made on a torch by Roger Parramore. The largest is over 36”.
