200g (ca. 250ml) gelwax. The best available quality on the market at super price, based on medical white oil. The wax can be melted in the plastic cup in a bath of boiling water. Take care, that no water gets into the wax. Even drops of it make the wax foggy. Content: 200g gelwax, 3 wicks 10cm. The melting temperature should ideally be between 80 and 100 degrees. Higher temperatures and a long residence time in the melting tank can cause oxidation (getting foggy or brown) results.
