I now have the book and have been trying to research something.
In the case of my pink cordial, I agree looking at his list of colours it seems as though the closest fit is 'Rose Alabaster' according to his book page 72 (note that they were unable to trademark the name alabaster and on page 26 he shows two more pieces in this colour and calls them 'rose alabaster' with no capitals).
However as I've said on another thread, I think that book is massively confusing particularly on the colours page.
Just one example of many examples I am confused by:
Under the headings
Opals Colour Shade Uses the author gives 'Rose Alabaster As name Bathroom accessories'
if the 'Uses' section is correct then the only pieces that could be called 'alabaster' are the bathroom accessories in what he describes as Rose Alabaster, Blue Alabaster, Pale Orange Alabaster, Jade Green since this the 'Use' he puts next to all those colours.
Clearly this is not the case, since I have a cordial which is unlikely to be used in the bathroom, and also a green lidded cup, which is identical to the rose alabaster cup he shows on page 26.
I also have a mauve alabaster with white alabaster foot bowl the same as the bowl he shows on page 26 yet mauve is not mentioned under the 'Opals' heading.
In addition to which there is, if I recall correctly, a beautiful deep mulberry alabaster powder bowl and lid in the Broadfield House Museum. That colour is not listed under his list of 'Opals' either.
Another confusion is-
he says under 'Opals' heading that there was a ' Pale Orange Alabaster' - again the 'Use' he puts for it is Bathroom accessories.
There is no mention of a colour 'Cinnamon'.
Yet on page 25 he shows a photo titled 'Group of coloured and white alabaster pieces, showing blue, jade green an cinnamon'.
Note that the word alabaster has no capital in that description and
there is no mention of the colour 'Cinnamon' in his colours list on page 72.
In addition to which, at the bottom of page 72 the page that lists the colours, it has a small note that says 'Casing colours are listed in Chapter 14' -
however when you turn to Chapter 14, in the text it says
'Colours can be divided into a variety of categories. Alabaster opalescent (my words - there is no comma between those two words in his sentence), threading, and picked-up powders have been dealt with in separate chapters, as has enamelling and gilding. The types of colour on which this chapter concentrates are: ...'
And he then goes on to describe what colours and ranges he is referring to in that Chapter 14. None of which seem to cover or refer to the 'alabaster' range.
( I mention this point regarding casing colours because the 'alabaster' range came in cased and uncased as far as I can work out from his comments and that I have examples of both)
He also describes Jade Green as being uranium glass on page 26. I have two pieces in Jade Green, one a custard cup and the other a powder bowl and lid and neither are uranium glass.
In short I think there is some confusion regarding the colours and the way they can be used. Or perhaps it's just me and I'm unable to read it properly.
