what is alabaster, and how many different types are there?
Le 21 mar 2008 par giovannibolton ()
Alabaster is the massive variety of the mineral Gypsum which is calcium sulphate. There is only one true alabaster but there are innumerable different names given to it due to the many different colours (due to other minerals such as iron oxide which stain the basic white gypsum) and layering forms. These are often taken from where the stone was quarried or how it looks e.g. zebra if it has black and white stripes. It should be called chameleon as it seems different each time you see it.
