The simplest method of making artificial amber.
The mass has the appearance of natural amber, but does not possess its hardness. The mass consists of 1 part of turpentine resin, 2 parts of shellac and 1 part of white rosin. All of these parts gently fuse together. In a tin vessel, the double walls of which are filled with oil to achieve a uniform temperature, turpentine resin is melted, and then shellac is added. Shellac gradually softens and combines with turpentine into an opaque, white, thick mass, which after some time becomes thinner and more transparent. When the mass becomes almost transparent, the rosin melted in a separate vessel is added. After a short time, the mass becomes completely transparent, liquid, and is ready for casting or pressing any objects, usually made from natural amber.
Depending on the color of shellac, the color of the mass varies from brown to lemon yellow. The lemon yellow mass can be made darker by heating. If you increase the amount of turpentine resin, the mass will turn out to be thinner and after cooling it will be softer and less brittle. From the increase in the proportion of shellac, the mass, on the contrary, becomes thicker, firmer and more fragile. Increasing the proportion of rosin also causes breakage. Mass can be polished and varnished. When heated, it becomes plastic, and with further heating it melts. To water, the mass is insensitive, but dissolves in alcohol.
