The crucible is something special and allows wax colours to be melted (and mixed) in the small heated pot. It is threaded to fit the encaustic art Stylus Pro wax graphics tool. Once the waxes have melted they can be poured out through the small tube in a flowing fluid line. Alternatively they can be poured out over the edge. When working with thicker wax residue it is best to work onto rigid surfaces like board or thick card so that the wax does not crack if flexed or bent too much. There are a lot of possibilities with this crucible and it is a great way to use up those fiddly little bits of wax colour that you can get left with. Well worth a play!
