You're sure doing some cool things with hot glass...

Have you ever heard of Brown's Gas? It's a perfectly balanced mix of hydrogen and oxygen because it has been electrolyzed, from water, on demand as it is used. Only one hose to the torch, both gases flow together. The flame is "cool" until it actually contacts your material.

I've fiddled with it quite a bit, but I'm no glass blower... however, I know of at least one maker of glass artifacts that swears by it.

Thanks for your fascinating stories of glassmaking; following you now! 😄😇😄
