Stone and cast stone
Published in Arthur Lyons, Materials for Architects and Builders, 2019
Alabaster is naturally occurring gypsum or calcium sulphate. Historically, it has been used for building, as in the Palace of Knossos, Crete, but in the UK its use has been mainly restricted to carved monuments and ornaments. The purest form is white and translucent, but traces of iron oxide impart light brown, orange or red colourations.
Rock Forming Minerals
Published in Aurèle Parriaux, Geology, 2018
Gypsum is widely exploited for plaster manufacturing: heated to 165°C, it loses some of its water of hydration; when it is mixed with water, it is rehydrated and progressively recrystallizes as gypsum. It is also commonly added to some cements as retarder of set. Alabaster is a variety of microcrystalline gypsum, of varied colors, that is used as an ornamental stone (vases, lamps).

Stanislas Sorel’s zinc-based paints
Published in Transactions of the IMF, 2020
On 12 March 1859, Sorel, in conjunction with Adolphe Hyacinthe Laissement, formed the Société Sorel et Laissement with the purpose of exploiting the patent for the oxychloride of zinc based ‘peinture Sorel’ as well as the ‘ciment Sorel.’ The company seems to have marketed its products straight to the trade, as advertisements in newspapers are very few.50,53 Sorel claimed that his compounds were so versatile that ‘these new compositions can replace in a great many cases plaster, alabaster, marble, ivory, caoutchouc, gutta percha, gelatine, pasteboard, papier maché, and several other substances.’54
