Thank-you!
So much for our posited "theories" about glass and food having descriptives in common.
It would appear that the nomenclature in glass and cooking is rather different.
I only know of timbales from a recipe - from the chef Michael Barry which I copied down from the tv over 30 years ago. His timbales were the same shape as the patty pan in question. A sloped sided thing that would turn out it's contents in a neat heap.
Not from ancient and official glass catalogues, where a timbale has a curved in rim and looks more like a cup.
And to think, I trusted Michael Barry implicitly!
