100% pure, natural beeswax pellets. Melting temperature 62-64°C.

In chemical preparation, wax can act as a barrier between rock/fossil and acid. Beeswax is more expensive than paraffin wax, and has a slightly higher melting point, but has better adhesion. Pure beeswax can be used, or a blend with Paraffin Wax. 

You could also use it to make some candles if you have the inclination.
