that reminded me, i had this random thought about bohemia crystal, which is a type of lead infused glass. i was thinking "hey, this probably blocks a lot of high energy particles and x/gamma/cosmic rays"

i'm wondering how to make this kind of glass. i think i know how to do the kiln stuff and it's just a matter of mixing up raw materials, so, i guess i get some lead and some regular sodium silicate and then cook them up for a few days in a kiln.

idk, weird obsession of mine but i want to build a geodesic dome that has a carbon and tin based radiation shield but still has passive light, without that light holes being wide open for high energy particles.

your fault for reminding me because bohemia glass is one of those kinds of glass which these days everyone knows as the brand svarovski.

it seems it's not just for the high density glasses that bohemia is famous, but glassworking in general. i love glassworking. i could definitely do more of it. it's very satisfying.
