Hip replacements and other devices implanted into people are made out of a combination of metals and ceramics. These certainly survive cremation. What do crematoriums do with all the salvaged pieces? Not being ghoulish, just curious…
When we cremated my father-in-law we signed a form at the funeral home giving them permission to donate his pacemaker to a group that reuses them in poorer countries. So morticians do remove some stuff first.
Here is a thread from (almost exactly) a year ago. Doesn’t fully address your question, but you might find it interesting.
this is a very good book from someone who worked at a crematory. https://www.amazon.com/dp/B00J8R3MYW/ref=dp-kindle-redirect?_encoding=UTF8&btkr=1
She also has a lot of good youtube videos
