British Gypsum launches brand-new website as part of wider commitment to improving transparency and supporting the industry in building better

Totally agree, BG market protection. The UK mines appear to be the only pink ones, and maybe softer material than the white ones. You can see in pics of the UK mines that it is pink underground but the only pics I've found of EU opencast are white.
Some of the UK gypsum is grey, I've used it as finish many times years ago and as Bonding more latterly.
