3D3DCopper copy of iridium slab. (External Sample)
Look under iridium and you will find a picture of Oliver Sacks holding a 1.7-pound slab of iridium I helped him have made in New Jersey. This is a copy of that slab cast in copper years later, hopefully the first of several copies made in different metals. I have a silicone rubber mold I made of the original and over time hope to make more and better copies. This one is not very good.
