I live in pride of my mercury-compound amalgam. You can choose to live in fear. "Numerous other organizations have also publicly declared the safety and effectiveness of amalgam. These include the Mayo clinic,[21] the U.S. Food and Drug Administration (FDA),[22] Health Canada,[23] Alzheimer's Association,[24] American Academy of Pediatrics,[25] Autism Society of America,[26] U.S. Environmental Protection Agency,[27]…

For better or worse, the dentists I have gone to in recent years don't use it any more. I have some old mercury fillings and at least one newer resin one. Your link is interesting. It seems like the arguments against mercury amalgam being a problem include: 1) organizations like you listed saying don't worry 2) obvious scammers making a living blaming everything on fillings, even nonexistent ones 3) only 5% of people…

Isn't indium used everywhere in solder as a less toxic replacement for lead?

AFAIK only in specialised low-temp solder, like the one sold by Chip-Quik to desolder sensitive components.

Trying to reconcile "extremely high price" with "we want to paint buildings with this stuff". Clue?

Why does that matter? The point is you can combine elements and create compounds that are drastically different to the components with different properties. Obvious one is water. H - explody. O2 - burny. H2O - puts out fires, quenches your thirst, no longer a gas, not very reactive.

Because corrosive is way different than toxic. Particularly, acid/base corrosion can and will be neutralized by our body once sufficiently diluted. Toxic compounds, especially heavy metals, stay toxic even if diluted.

Very insightful. Will be interested to know of your preferred 12 colour palette.

I use a Yellow Ochre Light, Pthalo Blue, Titanium White, Zinc White, Transparent Oxide Red (for blocking), Pthalo Green and Perylene Red :) Although, you can just use Richard Schmid's palette, replace all the toxic junk with modern pigments and you're good to go. The thing is to stick with the palette forever for many decades so that your paintings have a cohesive harmony.
