new research debunks trad views on nutrition

I think you are mostly right.
However gelatin is still made with beef or pork (there are vegetarian options also) and you can still find animal based glue (or so I was told by an antique restorer I was talking to).
They have ceramics listed rather than china.

I realize a few uses continue, and there will probably continue a small niche market for things like a few specialist glues as long as there are people who know how to use them (but most glues sold today are not made of animal byproducts). Ceramics are under Fat (I cannot think what that refers to off hand) but not under bones, where I would have expected them (see e.g. https://www.wedgwood.com/en-gb/welcometowedgwood/buying-guides/a-guide-to-bone-china)

They have ceramics listed under fat, not under bones. So they are still missing china (or ceramics) using bones.

And it's not a matter of listing each product just one place, because they have "plastics" in at least three different columns, with "textiles" and "cosmetics" in at least two places each.

Oh yes. Good catch.

Yup. You are right.
Gelatin and pet food.

actually, does anyone know any way in which beef fat would be used in the manufacture of ceramics? I rather suspect some confusion with animal fats being absorbed by some (notably, ancient) ceramics, so archaeologists can tell something about what the people who made the pot cooked or ate in it (but nothing to do with making the pot).

apart from tallow candles, I'm not familiar with any - but my only experience w/ clays is cursing my clay soils. and while its blazes hot here part of the year, its certainly not Kiln hot and dry.

As of 2020, 99% of the parts that Americans consider inedible is used for other things. I think it is still used for many of the things on that list but not in the same way it was used historically. This is not just from googling.

Several other sources besides in this thread say beef fat is used to make ceramics. I haven't found how, though. Google insists on telling me how to make ceramics without beef fat and how to use beef fat without making ceramics instead of what I ask.

This is one of my favorites:
Bone charcoal is needed for the production of high-grade steel ball bearings.

tallow candles

is that ceramics? I thought they were just candles (like wax, but made of fat)

it is very deficient for historical uses (bone was used for scores of different things, from buttons and combs, hinges and musical instruments, to numerous tools for other crafts, for example), so it would make sense if it's from the last century.

This is not just from googling.

ditto.

they are, usually in a ceramic bowl of some sort. Its "ceramic adjacent", not actually used in the ceramic. But again, my knowledge of clay is mostly cuss words...
