Alabaster: Kind of materials


ScaglioneThe “scaglione” is the most famous white alabaster, more or less transparent depending on where it’s found. It’s found in blocks that varies from 20-30 kg. to 1000kg. Also blocks of 2500 kg. have been found, but the procedures of mining risk to compromise the compactness of the stone.


AgataThe agate is the most precious alabaster, the most rare the hardest and therefor also the most difficult to carve. The yellow colour varies from very pale tonalities to a dark brown colour. The maximum of the blocks doesn’t exceed in weight 300 or 400 kg.

Depending on where it’s quarried it may have more or less evident black, grey or brown veins. Due to it’s transperency it’s mostly used for lightning.

Alabastro colorato

Alabastro coloratoThe alabaster, being a crystallized gypsum and therefor very porous, can easilly be dyed. The alabaster item to colour is put into a colour-bath for a fixed time depending on which intensity we want of the colour, and this method is used on both transparent and opaque alabaster.
