@@Chaoticfulisade I was almost going to include Arsenic, but I decided not to because arsenikon refers to the name of the mineral, not the colour, which is used to create the yellow pigment orpiment. Please correct me if I'm wrong, but I believe the yellow colour comes from the sulfur, not the arsenic. As for cyanide, that's a compound, not an element.

[@Abitibidoug]

So where's indium come from? In 1990 I was on a tour of the Kidd Creek Metallurgical Site in Timmins, Ontario where ore from the Kidd Creek Mine is processed to extract zinc and copper. Part of this metallurgical site was the Indium Plant, a small scale operation where this element is refined as a byproduct. As you saw in the video, it's quite soft, softer than lead or solder. Although not mentioned here, I think it's also used in making light emitting diodes.

[@AtlasReburdened]

A similar color can be obtained by melting a fairly thin piece of copper wire with an arc of 15000V and 10mA. The copper melts and beads up into a ball which begins to incandesce as the arc seems to more evenly distribute across the bead, the end result being that you can see the blue from the arc, the red from the incandescent copper and (if done right)where the two meet, a halo of rather reagal looking imitation violet.

Great videos... Clearly, you enjoy your work! Per the supply of indium ( 11:30 etc.), Indium is a byproduct of zinc mining. Sometimes (not always; but enough to matter) found within the mineral sphalerite ( ZnS ). So basically, world primary Indium supply is controlled at the mouth of the mine via zinc production. Mining matters!

[@jimh6867]

Thank you for the interesting video on indium. I have two concerns related to misinformation:1) Indium is not poisonous. This is easily fact checked with a safety data sheet from any supplier. You are not working with indium dust from a grinding operation.2) Indium supply is not running out. Prices are historically low due to oversupply. For more information please check the U.S.G.S. Recycling materials is always a healthy long-term strategy, and indium has a robust reclaim loop in place.
