There is a tremendous difference in hardness between pure and stirling
silver.

He was adamant that there should not be any residue , but clearly
results show otherwise
I even suspected that the silver may have been swapped out but I trust
this person and he has earned my trust and my silver kit said it was
silver but it cannot really differentiate between sterling and pure so
no point in that.
I have boiled it in vinegar and even cola for half a hour!
And then scrubbed them again to remove any silver compounds formed by
contact with the acids.
I will try the oven.
Any what about time? How long?
Thank you.

and it should burn off whatever he put on it. I can't imagine what
he put on--there was no need to add anything if he was thinning out a
piece of silver, unless he has some sort of hydraulic press or roller
that deposited lubricant to the silver. Odd, though. I've never
seen anyone do that before.

I did try my local jeweller / smelter but he contaminated it with i
assume is lubricating fluid, (i provided some Canadian maples for
this purpose), no amount of keeping it in vinegar Or Cola for its
phosphoric acid could rid it of the crap that would effuse out in the
brew!...even though they came out super shiny!.
