Titanium in 1791: Gregor mineral
Read the condition on Titanium before the nickname. Year 1791, line “Gregor mineral,” figure 4. Titanium is one of 32 materials in this atlas, grouped under metals: history, structure, measured properties, process routes, uses, safety and market — not a product catalogue.
Seven chapters follow. Fire and insulation claims name test families (Euroclass, ASTM E84, ISO 5660, KS F) rather than inventing a single safety number. Titanium (Ti (α/β alloys)) is a family of grades whose density 4.51 g/cm³, heat band 1668 °C, and fire letter A1 metal. Titanium is sold as grades, not as a single substance. Chemistry Ti (α/β alloys), density 4.51 g/cm³, heat band 1668 °C.
This atlas treats Titanium as a system: mill route, coatings, tests and the cavity it sits in. Conductivity note: ~22 W/m·K. Insulation score 14/100 is relative to 32 entries — metals lose, VIPs and aerogels win. Fire letter in editorial use: A1 metal. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.
Origin: Kroll process 1940, Luxembourg / US. The process chapter follows feedstock → conversion → forming → finish → install. Uses span buildings to defence / safety. Pairings matter: steel. Circularity mark 48/100. Ask which scrap, which certificate, which year. Related atlas entries, a short glossary, and three threads that keep Titanium honest.
The label keeps Titanium, 1791, and 4. “Gregor mineral” is the condition on the figure.1791
