Carnival Glass Colours - Amethyst and Purple
Amethyst and purple - what’s the difference? Amethyst has pink tones and is a rather light shade. Purple is a deeper colour with balanced blue and red tones. One of the main colourants was manganese. The list below goes from the lightest shades to the darkest.
Sun coloured purple – very pale, delicate purple base glass which is formed when manganese dioxide has been used as a decolourising agent in the glass batch to offset the residual iron impurities. When exposed to strong sunlight over a number of years, the trace amounts of manganese turn the glass light purple.
Lavender – a pale base colour, but the important ingredient here is the iridescence, which should be lavender in hue, although there are different schools of thought on this!
Amethyst – is a mid tone but the pink is very obvious in it. It can also be found with an opal edge
Purple – a deep, rich, balanced blue and red. A vivid iridescence on this can be called electric.
