I know a little about your background and appreciate your input about cinnabar/mercury. However, it really goes against everything we have been told. I won't cab that, malachite or bumble bee jasper. Can you explain to us why you are so confident that it is safe since no one else is saying it?
Inhalation of an insoluble compound depends on absorption to create toxicity (when tocicity is the same as poisin, which is not always the case). In order to absorb, it needs to be soluble, so that it can get into cells. Without that, all you get, for the lack of a better descriptor, is colorful boogers. The same thing is true for the forms of inorganic arsenic found in bumble bee jasper, orpiment, etc. Malachite is somewhat different, in that copper does not need to be organic or elemental to be absorbed. However, it being a micro-nutrient, the toxic dose is also higher. For this reason, a single/occasional exposures represent low risk. The problem is for those who receive chronic exposures -- in other words, those work with or are exposed to these materials routinely over a long period of time. They bioaccumulate, so the levels in the body build up over time, and gradually become toxic (this is also true for lead and other heavy metals, which is why certain fish should not be consumed on a regular basis -- they accumulated high levels of toxins over time, and eating one may not be a problem, but but eating them twice a week for ten years is another story). This makes chronic exposure different from acute exposure.
ETA: I understood it a desire to understand, not an argument. Also, I don't mind a debate, as long as people are polite and willing to hear (ping-pong, not archery).
