Title: Iridium Colors
Post by: snowman18 on April 25, 2020, 07:28:24 AM

This afternoon I smelted the catalytic powders into a collector metal, next step is to cupal this metal to recover a more pure platinum group.

The colors are from the iridium fraction, other platinum group expected are palladium, platinum and rhodium.

Looks rather like the colours found in our Australian Opals.

Australian Opals are one of my favorite gem stones.

This is the bottom side of the collector metal where the heavier platinum settled out. The platinum is the silver looking areas.
