Mineral wool in 1937: ROCKWOOL Denmark · 506
Read the condition on Mineral wool before the nickname. Year 1937, line “ROCKWOOL Denmark,” figure 0. Lower λ, combustible unless protected. A material is what it is made of, the condition it survives, and where it goes afterward. Mineral wool under “ROCKWOOL Denmark” in 1937 should say which, with 0 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.
