I recycle an old, weathered fencepost by stabilizing it in clear epoxy resin and then turning it into a pepper grinder. The resin used is Solid Solutions 606.
I show how I made a bowl that uses polyurethane resin, solid timber and swarf (timber shavings).
The Solid Cast 660 polyurethane resin was purchased from: www.solidsolutions.com.au They offer free shipping for orders over $100 but only in Australia. If you do order something through Solid Solutions please mention my name.
