Clambroth, amber, pink and yellow

 

Clambroth – a pale ginger ale base colour with a yellowish iridescence. There’s debate over this colour as some collectors say it is actually on a clear base glass.


Honey amber – clear base glass with a golden honey iridescence.

Amber – brownish base glass which may be coloured by iron, sulphur or selenium (a variation of the pinks). The shade of brown in the base glass can vary tremendously, from almost yellow to a deep brown. Fenton’s amber varies hugely; Joan Doty writes “Fenton’s amber was an accidental colour. According to Frank Fenton, Fenton amber is red that didn’t strike properly, which explains why Fenton patterns found in red are also found in amber. It also explains the wide range of Fenton amber shades, from pale yellow to deep brown”.

 

Horehound – Northwood’s version of amber, sometimes called Rootbeer, has a greyish brown effect

 

 

Riihimaki Tusenskona, pink

 

Pink – can be an offshoot of amber or possibly coloured with selenium

(Dugan/Diamond made their pink “Afterglow” range using selenium).

Very pale pink may also be colourless glass which was decolourised with selenium or arsenic (or a combination of the two in conjunction with cobalt oxide). This results in a very faint pinkish amber tint.

You can see this on some Riihimaki pieces – and remember they called Carnival, “Poison” glass. Using arsenic as a decolouriser wouldn’t have helped in the health stakes!

Pink may have a pastel iridescence, as in the Riihimaki Tusenskona (aka Floral Sunburst) bowl on the left,or a heavy marigold or amethyst iridescence which can mask the delicate base colour.

 Four Flowers Variant bowl, yellow

 

 

Yellow – can also be an offshoot of amber, while cadmium too, gives a yellow coloured glass (but note this will have a dull, orange glow).

Yellow can have a pastel iridescence, in which case the item is clearly yellow as is the case with the Four Flowers Variant bowl on the left. It can also have a heavier iridescence which can mask the base colour.
