The outer layers of the wonderful statue of Christ the Redeemer in Rio de Janeiro are apparently made of Soapstone.
Well, my husband isn't quite yet up to that quality of carving, but whilst staying in Brighton he spent a week learning the basics of Soapstone carving.
Presented with what he referred to as a chunk of rock, he worked all week shaping, filing, rubbing with a soft sandpaper, and finally polishing this lovely Heart paperweight.
The tutor was delighted with his work and said how difficult it is to get the two sides so equal, (and with very little sight I can't imagine just how difficult it must have been.)
Apparently Soapstone, also known as Steatite, has been used for thousands of years. It has a high Talc content which makes it soft and slightly soapy to feel, hence its name.
