The Alabaster, What is it?

The alabaster is a snow white material of fine uniform grain, but it often is associated with an oxide of?iron, which produces brown clouding and veining in the stone. The coarser varieties of gypsum alabaster are converted by calcination into?plaster of Paris, and are sometimes known as “plaster stone.”

In?Europe, the centre of the alabaster trade today is?Florence, Italy.?Tuscan?alabaster occurs in nodular masses embedded in limestone, interstratified with?marls?of?Miocene?and?Pliocene?age. The mineral is worked largely by means of underground galleries, in the district of?Volterra. Several varieties are recognized?veined, spotted, clouded, agatiform, and others. The finest kind, obtained principally from?Castellina, is sent to Florence for figure-sculpture, while the common kinds are carved locally, into vases, lights, and various ornamental objects. These items are objects of extensive trade, especially in Florence,?Pisa, and?Livorno.
