Care to share details about those?
Personally, the latest for me is a few DAAB concentrate cups, Post#80,
I don't think it will be long until you start seeing some custom glass options for this. I know Paulson is working on caps at least. @Hapo it's nice to see you gave it a shot. Personally I don't find the maintenance any more taxing then any other e rig and it's nice not having to worry...

Crazing/frosting is caused by overheating (don't use a propane torch for cleaning to save butane) a filthy banger (devitrification, I had to look that up) to others having the bottom fall off bangers (usually frosted bottom jobs).
A quote I found about devitrification:
Temperature is the catalyst of devitrification. At room temperature, quartz is fairly stable. Atmosphere and surface contaminants are not much to worry about without the addition of increased temperature. The sources vary on the temperature at which devitrification occurs. Some say the phenomenon almost never occurs below 1,150°C (2102°F) as long as no surface contaminants are on the quartz while others say devitrification can happen at temperatures as low as 1,000°C (1,832°F).
[3&4] It can even occur at temperatures well below 1,000°C if any surface contaminants are on the material. Devitrification in open atmosphere, absent surface contaminants, normally occurs at temperatures exceeding 1,200°C and accelerates with any temperature increase.
[4] For reference, butane torches are claimed to develop flame temperatures of up to 1,430°C (2,610°F)
[5] and propane torches can reach 1,995°C (3,623°F).

Over the past several years, the market has had a change of opinion on proper nail use and care. In the beginning it was believed that nails had to be "seasoned" or that a "season layer" had to be developed before a nail could be used optimally. Depending on who you talked to, the purpose and...
