Quartz glass needs much higher temperature than borosilicate glass and usually Hydrogen-oxygen torches are used for this work. Hydrogen burning is much faster and this flame can produce flame over 400 deg C hotter than propane.

Lab glass or art glass? Art glass blowing is done in many schools and the fuel is whatever is cheapest: natural and propane being the most common.

Subject: [DCHAS-L] Fuel gases and gas blowing operations
I am interested in knowing what fuel gas is being used at institutions with gas blowing operations involving quartz glass and best practices being used. Also, could someone point me to a good reference for this type of work?
