Metal Bars: Casting

Since I get these questions so often, I'll answer them here: I bought my crucible and mold from eBay. They are both made of graphite, and usually the metals simply fall right out of them when cool. Powdered graphite is used as a lubricant, so things don't usually stick to it.

In this video, I melt and cast various metals into bar shapes, using graphite crucibles and molds. These sets of metals are sold some places as teaching sets to show students the differences in physical properties of the metals, such as density, color, and hardness. I'll be using these bars in a future video to demonstrate such properties.

I've wanted such a set for a while now, and I figured why not make it myself!
