As a point of curiosity has anyone collected the gold or platinum used on glassware or ceramics for decoration?
If so has any of it amounted to anything?

I've done some testing with HCl-Cl on gold 'glazed' ceramic with success, but I don't have any solid yield data.
I more or less performed some proof of concept experiments that confirmed HCl-Cl will quickly remove this type of plating even at room temperature.
Sorry I don't have more information.

Both the platinum and gold types?
Just as a guess I would presume it would take a mass quantity of glass to accumulate a significant amount of either however there are mountains of the stuff out there.
The thickness is likely just past the limit of appearing transparent. I suppose with the right scale of extreme accuracy you could determine how much was removed easier than how much was recovered.

The only 'Platinum' ones I have are marked 22kt Platinum so I'm not 100% sure what they are, but they are silvery gray colored.
The HCl-Cl worked for both the golden ones and the silvery ones.
The problem with weighing the item that the plate is removed from is that the porcelain is very porous and tends to absorb moisture making it hard to determine what the actual weight is.

the plating is so thin when you hold them up to light you can see through it. its kind of green with light shining through, I save up a batch and strip them in a 5 gallon bucket, or dish pan depending on size, and I wont give much more than a quarter or fifty cents for the dish as yield may not even be worth that, afterward I wash dish and give back to second hand store to sell again.
