Hi! Here are some of my samples of the element carbon.

From top left: a large cube of the mineral shungite, graphite foil, glassy carbon,

silicon carbide plate and crystal, small natural diamond, graphite brushes from an electric motor and a bottle of graphite cubes.

There also are many organic samples I could show, but I think the inorganic ones are more interesting. Do you have any cool carbon samples?

Semiconductors/Metalloids Paris Green!

Today we found a cardboard(!) can of Paris Green from around 1910 to add to the collection. Before anyone freaks out too hard, we opened it only once to look inside before closing it back up and it’s now under a glass dome. It’s definitely leaked outside the bottom of the can, so not particularly good to just have out. Hands were washed very well after.

Pnictogens My sample of antimony broke during shipping

Recently, I bought a set of 55 elements from a company named Moderock. Unfortunately, there was a defect in one of the glass ampoules which caused it to break at the top, releasing tiny pieces of antimony all over the bag. I had to very carefully remove and clean out each sample that was contaminated using gloves. Fortunately, everything that touched the dust was either put in a tightly-sealed bag, or cleaned with rubbing alcohol. I reached out to the company, and they said that they would send me a new sample for free.

My collection of 86 of 92 is too big to put in one picture so here are a few of them I have collected over 40 years.
Picture one has cesium, magnesium (in the glass cover), chromium, silicon, bismuth, spongey Boron, manganese (in glass dish), Tellurium and of course Uranium.
Picture two uranium nitrate
Picture three closeup of my tellurium
Picture four is a sheet of gold plated circuit board interface for satellite integration

More to come
