Soviet amber crumb (amberoid) + composite plastic may be epoxide material chess set (USSR).
The production of the Kaliningrad amber factory, 1980s.
Pressed amber (amberoid) + plastic, may be epoxide composite material.
! It is not the original amber. Maybe it produced from the pressed amber crumb + plastic epoxide.
I think it is made principally from some kind of plastic masses.
It is specific and nice chess pieces.
Board is 41x41 cm.
King is 10.2 cm.
Pawn is 5 cm.
Total weight of the chess set is 2.2 kg.
Damages: scratches on the lacquer of the board.
Manufacturing technology: small pieces were ground into powder and placed in a mold. Under the pressure of 1000 atmospheres at a temperature of 180-220 With the powder has turned into a sticky mass. When a special pressure mode with the addition of dyes received pressed amber (amberoid) of different colors and structure. Currently technology is not being used due to its very high energy consumption.
The Soviet Union waged a large-scale extraction of amber, worked extrusion technology amber chips, was awarded the GOST and flooded the domestic market with quality goods amberoid. So, now that the Soviet amberoid is not considered imitation of amber. His status is as a precious stone in a reduced grade. With all the controversy of such language, it should be recognized: amberoid 100% consists of fossil resin, fossilized over millions of years of being in the ground.
The costs of the chess were 30 rubles. It is 10-15% of the average month salary in the USSR.
So, it is not big cost for the amber and too big for plastic. It is composite material, I think.
