Glass in 50: Blowpipe
DFT, moisture meters and compression of batts are quality tools, not bureaucracy. Keep Glass with “Blowpipe” and 50 from 50. Primary Glass carries process energy that recycling or bio-routes only sometimes beat.
This atlas treats Glass as a system: mill route, coatings, tests and the cavity it sits in. Conductivity note: ~1 W/m·K. Insulation score 28/100 is relative to 32 entries — metals lose, VIPs and aerogels win. Fire letter in editorial use: A1. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.
Origin: Mesopotamia / Egypt; float 1959, Near East → St Helens. The process chapter follows feedstock → conversion → forming → finish → install. Uses span buildings to defence / safety. Pairings matter: technical-ceramics. Circularity mark 70/100. Ask which scrap, which certificate, which year.
Related atlas entries, a short glossary, and three threads that keep Glass honest. Crystalline cousins that do not flow like glass. Glass wool is the fibrous insulation form. EN 13501-1 reaction-to-fire letter (A1–F), not a wall rating. Thermal conductivity in W/m·K. Lower means better bulk insulation.
The label keeps Glass, 50, and 50. “Blowpipe” is the condition on the figure. Keep Glass with “Blowpipe” and 50 from 50. 5050
