Funny how this comes up today!
Last night on 'Naked Archeaologist' the show was about the colour blue in
ancient times. How it was produced from the snail. The trick to getting
blue from the snail was to expose the dye to sunlight. The ultra violet
light produces a very vivid blue, if not exposed the dye will come out
purple.
I thought it was fasinating.
There is also quite a controversy in some sects of the Jewish faith over the
use of snails or cuttlefish to produce the dye. The archeaological evidence
suggests snails though, due to the amount of snail shells at dye sites.
How they suggest the dye is made
rotten dried up snail
caustic soda
boiling water
sunlight
I am not a dyer, so I don't say this would work, I also don't know the
quantities of each. It was interesting to see them dye the fibre
though...when it first came out of the dye pot it was yellow, then once rung
out of liquid and probably exposed to the air turned blue before their eyes!
Discussion?????

On another list I am on, a topic coming up regarding the relevance the
colour blue is to Jewish women came up, relative to the Book of Judith and
all the spin off paintings it has created particularly in Italian ren
paintings.
