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.

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?
