The only solders that contain cadmium are Easy low carat gold
solders (9K-12K) and Extra Easy Silver Solder, as in both cases
they are used to lower the melting temperature of the alloy.
Cadmium smeared on the face isn’t good for your skin, but isn’t
toxic. When you vaporize the metal, it is quite dangerous. It
is carcinogenic and pretty nasty stuff!
