Drinking from an aluminum can, no my lips don't swell up but if I wear deodorant containing an aluminum derivative I break out in hives. I'd rather er on the side of caution and not inhale or have prolonged skin exposure to aluminum containing rocks. There's a very important distinction that has to be made here. Aluminum in a can is essentially Al° (that's supposed to be a superscript zero, best I can do from my phone) or elemental aluminum. However it reacts very quickly with oxygen in the air forming Al2O3 or alumina which is fairly inert. That's what is actually in contact with your skin. Deodorant (antiperspirants) on the other hand is aluminum zirconium tetra... something something. In other words, a totally different compound. It was designed to react with sweat to make a "plug" that prevents any more sweat from leaving the pore. Far from inert. What I'm trying to get at is that almost any given element can be a problem (or not) depending on what compound it is part of. It's an over generalization to say that aluminum is safe because of how many people can drink from soda cans and not have a problem. The same is true if you say it's toxic because of vaccine sensitivities or deodorant allergies. I agree and stated earlier the term toxic is not the correct term to use, potentially harmful I guess is more appropriate for minerals such as this, and why discussions like this is important

nice to know you is having a few. Cadmium is certainly an issue, but with lapidary materials?? If we include asbestos-form stuff then we cannot call it "toxic" but instead another adjective such as you describe "dangerous". Although calling asbestos "dangerous" in a lapidary setting is contentious at best. Tigereye is mostly asbestos fibers. I like it. Cadmium is coated on most of the screws and bolts used on everything. It is coated on racks id refrigerators. People used those racks for smoking fish etc. and got cadmium poisoning. I never heard of anyone dying from it though.

I worked around asbestos for 40 years and lost 30% of my lung capacity because of it. I expected to turn my toes up around 2000, but several years of drinking a tablespoon of apple cider vinegar in a glass of water every day for several years somehow removed the fibers! Are you still drinking the vinegar? 39don No, I quit around 2003, but still have a glass on occasion.

Cadmium is coated on most of the screws and bolts used on everything. Actually, three months of fastener sales has shown that today cadmium fasteners are only used in military/aerospace applications. When we want a cosmetic yellow we get Zinc/Cr +3 coating. Trivalent chromium zinc plating is yellow and rust resistant. That is, in my short experience the only places I see cadmium.

Thanks Scott (Shotgunner) for adding a tone of rational reasoning to a potentially electric topic. We have a rule in our lapidary lab, "if it tastes bad, or smells bad while you are cutting it or polishing, it probably is bad for you. So to are somethings less obvious but reduce the dust and don't eat anything you don't want to end up in your liver and you will be mostly safe. Tom

Finally I am in the 1%!! I must eat gluten/wheat free. lol A very high percentage of people exposed to lead in the form of bullets have life threatening health issues. Yet, we do not walk around all day worrying ourselves about this possibility. Why? 'Cuz it is so rare as to be noise and not worth listening to. So is aluminum poisoning. "A very high percentage, but not Fearless! "Take two aspirin and call me in the morning." ?? We are not all the same, so this list would have to differentiate somehow.

For the public record. I am against stuff that actually harms us and for everything else. This includes stuff the worst first folks claim are bad, like asbesto-form materials. I suppose bumble-bee stone tastes bad? yes? no? maybe so?

Tigereye is mostly asbestos fibers. I like it. Not really. To quote Wiki, "Tiger's eye (also called Tigers eye or Tiger eye) is a chatoyant gemstone that is usually a metamorphic rock that is a golden to red-brown color, with a silky luster. A member of the quartz group, it is a classic example of pseudomorphous replacement by silica of fibrous crocidolite (blue asbestos). An incompletely silicified blue variant is called Hawk's eye." So in other words if it's gold or red and not blue or greenish there is no asbestos in it. If it is blue or green and will polish at all there isn't much asbestos left in it, as the asbestos by itself won't take a polish at all. That doesn't negate the risk of silicosis from the quartz replacement, so the dust should not be inhaled or otherwise ingested, just like any other stone.

Cadmium used to be a component of silver solders used in jewelry-making. The fumes given off when heating it can be very dangerous. Cadmium's no longer used for that reason, but it's something to be aware of when using old solders from estate sales etc.

What up lapidaries? My radiation sense was tingling. Pretty sure it's been covered ad nausium, so I won't beat a dead horse.
