Do-It-Yourself Cerrosafe

[Cap'n Morgan]

As the title says: Has anybody tried making your own? For true low melt cerrosafe alloy you need Cadmium as one of the elements, but for "Rose's Metal" you only need bismuth, lead and tin, and the alloy will still melt in boiling water. Rose's metal is two parts bismuth, one part lead and one part tin. This can easily be accomplished with one part bismuth shot (three or four shells should do) and one part 50/50 solder.

I could buy the original stuff, but it's pretty expensive over here.

bismuth shot has 5-10% tin in it IIRC

I've used candle wax for making a chamber cast. Was quite impressed with its ability to be measured.

I've long used melted sulphur powder ("Flowers of Sulphur", from a drug store) to make chamber casts. The casts are a bit brittle but it works very well.

This. It is easy and repeatable and you can save the castings for future reference and write on them with a sharpie marker.
