View source for Ceresin wax

=Description=
Ceresin originally was a purified ozokerite. For economic reasons, it was adultered with paraffin wax to reduce its cost. Today commercial ceresin contains 50 - 80% paraffin wax. Some European ceresins also contain rosin and coloring matter to approach the properties of [[beeswax]]. 

Commercial ceresin varies in color from yellow to white and melts at 54 - 79ºC, depending on its purity. Its hardness, plasticity, etc, also vary with purity. The grades containing large percentages of ozokerite naturally approach ozokerite in properties<ref>Bennett, H., Commercial Waxes, Second edition, p. 108</ref>.
