I love these pieces. They need to be lit and show at their best under evening lighting. There is something really ethereal about them because of the way they are made and the recipe for the colour I think. The alabaster 'attachments' are the very best, slightly greyish, slightly translucent, perfect.
They are my favourites of all the opalines, next only to early French opaline glass 'gorge de pigeon'.
The green is a pale green. I've only found or seen one other in this lidded cup shape. It's in the book (in Rose), although Manley also shows the cup without a lid.
The turquoise is marked on the bottom and is a beautiful colour.
As is the mauve bowl, which could be Puce (mauve) or Violet (pale mauve pink) according to The Crystal Years.
The green has the foot applied in alabaster and also has alabaster thinly cased part way up the cup. The same with the turquoise vase. But the part casing is done differently to a rose cordial I had where the stem almost appeared to be part of the bowl because the casing was drawn up over the base of the bowl. On both of these two pieces you can see where the foot is applied but they both also have a fine thin part alabaster casing part way.
The mauve bowl is made in three parts.
It's fairly unusual to find marked Stevens and Williams pieces although they do come up. The mark on my vase is not shown on either Great Glass or the Style site under their marks. But it is the same as the one in CH British Glass 1800-1914, page 449.
CH says of the mark in the book
'15. Faint acid etched mark with the fleur-de-lys between the initials S W on a slender green alabaster vase with white alabaster foot, late 19th century, in the Broadfield House Collections. Height 5/8 in. 1.7cm'
The Crystal Years discusses the Alabaster range for the years 1914 and 1916 but no start date is given.
Charles Hajdamach also says in 20th Century British Glass that 'Bath Powder Bowls' first appear in the pattern books in 1919.
I've taken two pictures to show the different effects of lighting on these pieces
