Cotton in 1764: Spinning Jenny / mule
Read the condition on Cotton before the nickname. Year 1764, line “Spinning Jenny / mule,” figure 79. When cotton FR finishes are not enough. A material is what it is made of, the condition it survives, and where it goes afterward. Cotton under “Spinning Jenny / mule” in 1764 should say which, with 79 tied to the condition. A figure with no condition is a boast. Readers meet the name on the back of a product, so the code and the history should not share one sentence.
Scores compare Cotton 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.
Cotton (cellulose (C6H10O5)n) is a family of grades whose density ~1.54 g/cm³ fibre, heat band chars ~150 °C+, and fire letter combustible fibre (treatments vary). Cotton is sold as grades, not as a single substance. Chemistry cellulose (C6H10O5)n, density ~1.54 g/cm³ fibre, heat band chars ~150 °C+.
This atlas treats Cotton as a system: mill route, coatings, tests and the cavity it sits in. Conductivity note: low (textile still air). Insulation score 40/100 is relative to 32 entries — metals lose, VIPs and aerogels win. Fire letter in editorial use: combustible fibre (treatments vary). Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.
