Topic: Fruit Bowl in opaque yellow (colopal)

I couldn't resist buying this last week.

It's made of 'colopal', an opaque yellow glass made by Leerdam in the 1920s - 1930s, but this pattern is unlike anything that I can find in the literature.

Perhaps it's not Leerdam, at all but another factory experimenting with the recipie?

Any clues or tips welcome!

Does Leerdam colopal all have slight swirls in the color?

Several American glass companies made a similar pale yellow opaque glass - Fenton and Cambridge are 2 that come to mind.  I collect Fenton Chinese Yellow which is a pale opaque yellow.

Also I had a pale yellow scent bottle that I am fairly certain was French which I sold several months ago.

It's very variable, Connie. I have seen authentic pieces with clear 'swirls', but I regard this as a 'flaw'.
Generally the glass has a consistent colour, and most museum examples do not seem to have any swirls.

Could you give me an indication of the sorts of designs that these companies used for this type of glass? (website or book reference would help) and then I can pursue it further!

The early breakfast service by de Zwart and de Bazel was a strong vibrant yellow. Colopal (the breakfastware) was slightly paler 'primrose' shade, and in some (later?) examples became even lighter with a slight greenish tinge (nearly 'ivory').

The pudding mould 'leaf pattern' was produced in the stronger tint of yellow but the glass is actually only 'semi-opaque' if you look carefully.

The pudding mould 'classic dome' appears to be the same primrose shade as 'Colopal'

The Cambridge color was called Primrose and was only made for 1 or 2 years starting in 1923.  I woukd suggest the book Colors in Cambridge Glass by the National Cambridge Collectors, Inc. or their website

For Fenton Chinese Yellow the best book is Fenton Art Glass 1907-1939 by Margaret & Kenn Whitmyer.  Chinese Yellow was introduced in the early 1920s and the name Chinese Yellow was used as early as 1924 and made until around 1933.

Your bowl does not look like a Fenton shape and I doubt that it is Fenton.  I was more commenting that the pale yellow color is not a unique coloration.
