Japanning is most often a heavy black lacquer, almost like enamel paint. Black is common, and japanning is often synonymous with black japanning. The European technique uses varnishes that have a resin base, similar to shellac, applied in heat-dried layers which are then polished, to give a smooth glossy finish. It can also come in reds, greens ...

The pattern and shell together are placed in an oven to finish curing the sand. The shell now has a tensile strength of 350 to 450 psi (2.4 to 3.1 MPa). The hardened shell is then stripped from the pattern. Two or more shells are then combined, via clamping or gluing using a thermoset adhesive, to form a mold.
Polishing is the process of creating a smooth and shiny surface by rubbing it or by applying a chemical treatment, leaving a clean surface with a significant specular reflection (still limited by the index of refraction of the material according to the Fresnel equations). [1]
The material then can enter an oven or be sanded again depending on the manufacturer’s setup. The material can also be recycled through the line to apply another coat of finish or continue in a system that adds successive coats depending on the layout of the production line. The systems typically used one of two approaches to production.
