Silverport, you are a wealth of knowledge. On the heavy side of the tray. It is a plain round tray with a diameter of 310mm and a weight of 923 grams. Almost 1 kg of weight in what we consider is a small tray. We will take your advice and visit the dealer again, and we will also make as many enquiries through our other silver friends. We were thrilled to find the tray in the beginning, 16 years ago in St. Petersburg, so any information on its history is really the icing on the cake. Once again, many thanks for your invaluable help. Best regards, JnJ.
For reason of curiosity I’ve made some brief calculations of approximation.
Hello again
I’ve made some brief calculations. They are an approximation only; because I don’t know the decorative details of trays rim. But that is of influence only on diameter related details. In these brief calculations I’ve also ignored the surface plate; because its weight is already included in the trays basic weight of 923 gram.
Basics: Tray of 310 mm diameter, and weight of 923 gram.
1 cubic decimetre of the following alloys have a weight of:
»Geitner« alloy = 8.4726 kg
»84« zolotniki = 10.29375 kg
»Sterling« = 10.37225 kg
If the tray is made from a similar alloy as the »Geitner« alloy is, then his Volume is in cubic decimetre:0.1089394; by a weight of 923 gram.
If the tray was made from a »84« zolotniki silver alloy, then his Volume would be in cubic decimetre:0.089666; by a weight of 923 gram.
If the tray was made from a »Sterling« silver alloy, then his Volume would be in cubic decimetre:0.0889874; by a weight of 923 gram.
If the tray was made from an »84« zolotniki silver alloy, and would have the same Volume in cubic decimetre as now:0.1089394; then the trays weight would be: 1.1213949 kg.
If the tray was made from a »Sterling« silver alloy, and would have the same Volume in cubic decimetre as now:0.1089394; then the trays weight would be: 1.1299466 kg.
