Vidrio is one of 32 materials in this atlas, grouped under ceramics: history, structure, measured properties, process routes, uses, safety and market — not a product catalogue.
Scores compare Vidrio with the rest of the atlas on strength, heat, fire behaviour, insulation, workability and circularity. They are editorial, not certificates.
Seven chapters follow. Fire and insulation claims name test families (Euroclass, ASTM E84, ISO 5660, KS F) rather than inventing a single safety number.
Introducción profunda
Deep dive: Vidrio
Vidrio (SiO2–Na2O–CaO (typical soda-lime)) is a family of grades whose density ~2.5 g/cm³, heat band softens ~500–700 °C, and fire letter A1.
What “the material” actually is
Vidrio is sold as grades, not as a single substance. Chemistry SiO2–Na2O–CaO (typical soda-lime), density ~2.5 g/cm³, heat band softens ~500–700 °C.
This atlas treats Vidrio as a system: mill route, coatings, tests and the cavity it sits in.
Heat, fire and insulation
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.
How it is made and used
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.
Market and circularity
Producers below are landmarks, not an endorsement ranking. Prices are bands, not live quotes.
Circularity mark 70/100. Ask which scrap, which certificate, which year.
