I can get to a sand blaster which I'm very interested in doing but wouldn't frosted glass be kinda like devitrification all over the quartz? I could see how the concentrate might soak in (like ceramic) and vaporize better with the increased surface area but I imagine a frosted banger would be a bitch to clean (like ceramic) and would devitrify much faster leading to more and more sandblasting.
