It really DOES have arsenic in it.
I have access to equipment that can detect most elements in just about any type of sample. So I ran a slab of bumblebee. Mostly calcium from the travertine type matrix, but with some sulfur, arsenic, and iron.
I guess the yellow color is orpiment then?

The yellow is sulfur. This rock comes from volcanic lava pools and sulfurous hot springs in Indonesia. BTW - be VERY careful to wear a good respirator if you grind or saw any of this stuff - There's arsenic in it.
c-ya,

I guess that's a rock you shouldn't lick, then, eh?

The easy way is qualitative, but it is capable of quantitative if I feel like futzing with the helium regulator. I can detect just about anything on the periodic table between magnesium and uranium except for the noble gases. |

This is special material as it is hard as jasper, but the color of variscite. |

when we first open the container at Tucson the sulphur smell is overwhelming from the Bumblebee. Even the crates make the tent smell if theres no breeze
