Hot Glass at the Glory Hole (click for Sitemap)
Furnace glassblowing is my hobby/avocation. My web site is dedicated to spreading information about off hand glassblowing: gathering glass from a molten pool in a furnace and working it on pipes and punties, especially lower cost choices.


In support of this site if it is useful to you.

I am reasonably impressed by this free search engine, let me know what you think. Contact Mike Firth (and this is a site for furnace glassblowing, so there is nothing here about making bong pipes or working Pyrex.)

A WARNING: Working glass is inherently dangerous, involving heavy materials that can be razor sharp, so hot that damage can be done before feeling occurs, with chemicals immediately poisonous, dusts that can damage the lungs, and heat sources that can wreck the eyes. Understand the safe practices required and use them to blow beautiful glass. Safety
