I believe your intentions are honest, but when you say;
It is my intent to fully describe and disclose all I can about a piece.
You need to add the word "factual"
to that too. Neither of those two items your links go to are Vaseline Glass. Looking at the photo of the items and the black light in your auctions it's easy to see they are not producing any green colored glowing effects like Vaseline Glass should, but are simply reflecting the light back from your black light is all.
Have a look at this completed auction.LINK
That shows what the glowing black light effect on Vaseline Glass should look like, bright green light that arrears to come from inside of the item itself, rather than from the black light.
Those glass items you have listed are more often referred to as Amberina Glass on ebay, not Vaseline Glass. A buyer might win your auction, but when they get that glass in their hands and realize it isn't Vaseline Glass you might end up having a problem on your hands, so that's what I mean about adding Factual
to your ebay selling intentions.
It's a pretty common mistake, I have noticed that a lot of people don't quite understand what effects they should be seeing with a black light and Vaseline Glass. Seems they only know "Glowing"
and make some sort of assumption on that word alone.
