[ANON POST] Persuading Lavoisier that Sapphire Is an Element

I'm writing a story part of which is set in 18th Century Paris shortly after Lavoisier's publication of Méthode de nomenclature chimique. One of my characters wants to convince Lavoisier that Sapphire is an element. They do not need to succeed but I'd like an idea of the evidence they might put forward and how (and if) Lavoisier might counter it. The character isn't a scientist but is a lady of leisure with an interest in current developments in science.

For instance, I'm unclear whether people would have been aware, at the time, that Sapphire was an oxide (or at least decomposable - because contemporary confusions about oxygen). Might Lavoisier have been aware but an interested lay person not aware?

Basically I'm looking for a plausible for circa 1790 argument that Sapphire is an element that is framed with reference to Lavoisier's treatise.

I've read the wikipedia pages on Lavoisier, Sapphire, Corundum and Chemical Nomenclature. I've searched on "Méthode de nomenclature chimique", "Sapphire history", "Sapphire history chemistry", "Corundum History"

Child custody in the UK

Time: present
Place: England - more specifically, Surrey and Devon

Research was made on websites about both the laws on child custody and on help available to families with a child with Down Syndrome, but I have found nothing to help me figure out whether or not some details I have thought up are anywhere near believable - if anyone could help, that would be brilliant!

The scenario: The parents of a child with Down Syndrome (residing in Devon) die suddenly. Her next of kin is an older half-sister (residing in Surrey) who was not aware of her existence until the police notified her their shared father's death. She is also the only relative the child has left who has not already declined to take her in.

Any input would be much appreciated - thanks in advance!
