Copper cycle redox lucite block paperweight embedment
LUCITE, POLYESTER RESIN, EMBED BLOCK
This is a very unusual and uncommon lucite block. Old stock from a closed biological supply company. The maker of this block is NO LONGER IN BUSINESS and very few of these were made.
Older item. Minor scuffs as typical with these older blocks, but overall in very nice shape.
Features: Copper (copper nugget) - Oxidation with HNO3 (clear liquid in vial with some white spots around it) - Cu(NO3)2 (greenish material in vial) - CuO (flake/chips in vial) - Reduction with Carbon (carbon piece) - all in a nice circle/cycle pattern.
Size: about 3-3/4 X 4-3/4 inches.
