I'm looking for a way to diffuse the light from a northstar lantern. I've been using foil half shields for years but would like just a diffuser or shade that won't burn up. I tried soaking the glass in acid but it's pyrex or some similar borosilicate and the acid didn't touch it. I googled it a little and it seems inductively coupled plasma works but uh... yeah.
any ideas out there of what would etch it or has someone found a good material for a high temp lamp shade?
