There were later triangular very chunky tricorn perfume bottles, with an Earthtones core.
These large deep flat pieces, are too closed over to be a bowl, for me.
A bowl is wide open and welcoming - this hides things.
But I couldn't call it a vase either.
You did have mine for a bit John, I take it it was that one?
I have seen one that was almost a ball, quite narrow but tall.
Different sizes and variations are to be expected. Nothing was made in particular sizes to start off with. They were not even trying to replicate pieces - a selling point was that each is absolutely unique.
It couldn't be anything else when they were using silver salts to create the colours in each, I really suspect they just didn't bother about sizes being accurate.
