Toxicity of Rainbow Calsilica
I have the same question about “rainbow calsilica” or “Duronite” as
I think we should call it. I wonder about the presence of pigments
such as the cadmiums which can be troublesome.
I just found a site on the web which references the composition of
topcoat automotive paints. Among the pigments used are the lead
chromates (yellow, oranges, etc.) and iron oxides. If you’re
cutting/cabbing any of the "newly found like Detroitite,
calsilica, or whatever, watch out for the inhalation of these
pigments, or transfer through the skin.
