At one time Mercury was used in the making of hats. It is suggested the Mercury vapors made the workers rather peculiar, hence Mad as a Hatter. In the dim and distant past our factory was used to make hats. Whilst we were digging the foundations for the support of a new overhead crane we came upon the old Mercury Vats. Maybe that accounts for many things. Haha Ivory Flame and Cariad needed no excuse to produce these images. They are just Mad!!!!!
