Re: film on wax after boiling
Found this in a wax book pdf that someone sent me...
• Water-wax emulsions
1. the wax-water appears milky, due to the presence of calcium or iron in the water
Use 2-3 g of oxalic acid per kg wax and 1 l of water to bind calcium, prevent emulsion and to
brighten wax at the same time.
2. wax absorbs a greater amount of water: heat wax at 105 oC to remove water.
• Wax has a crummy structure
This is due to saponification of wax. The process can be reverted by boiling wax with sulfuric or
oxalic acid. Use soft water to prevent this, e.g. rain water. Water with a low mineral content should
be used if such problems arise. However, in some cases, water/wax emulsions can occur, even with
soft water. In such cases, raw molten wax in contact with water should be kept below 90°C.
