Russian Chemistry Wheel

8/18/2016

 
As promised, here is our priciest wheel and it was worth it. This Russian chemistry wheel is eight inches in diameter and is made of a heavy cardboard upon which a thin layer of plastic (kind of like contact paper) has been affixed. The whole thing is sealed off with a metal edge. I wish I knew how old this is. I suppose that if you could figure out which element on this is the newest, then you might make a pretty good estimate.

At the top of the wheel, you can dial an element and read its atomic weight, density and number, among other things.

I like it that's it's pink. What an odd color choice. I sure would like to know what this wheel was used for. Perhaps it's a learning aid or a tool in some industrial chemical field. If I find out, I will let you know.
