You're right Pete, Chippendale pieces are seriously weighty! Some of the lids are complete, some have a central hole, as the pot was done as both a powder pot and as a hair receiver - and you rescued the hair from your brush or comb and stuffed it into the little pot for later reuse as stuffing for small items such as pincushions, or it might be made into hair extensions such as ratts, or even small decorative shapes put into lockets. The Victorians had some funny ideas about hair! (Funny to us, seen from the 21st century, that is!)
I think my pic was taken with our old camera, which was really good for glass. Sadly it was dropped and broken, and the later model replacement isn't a patch on it.
Chippendale-style pieces appear in the catalogues of various makers in the UK, USA and Germany, so there's a lot about! They aren't all proper Chippendale though.
And the quality does vary a bit.
Can you post your lidded amber pot with a saucer into a new topic please so we can take a look? It sounds more of a butter dish style, but with a pic we might be able to tell you for sure.
