Topic: Colours available at Mdina in 1976.........

[Patrick]

Hi,

In a current topic by WhatHo asking about White glass http://www.glassmessages.com/index.php/topic,63272.0.html there has been a mention of Tiger and Tortoiseshell and also a fish by Boffo has been discussed using White and other colours.

I have found this vase for sale dated 1976 and it clearly shows colours available at that time. https://www.etsy.com/uk/listing/275178370

I will contact the seller and ask if his image can be saved and included in this topic.

Cheers,

Patrick.

That doesn't have white in it, the bit that looks like it might be in the photos is just a reflection.
Tortoiseshell and Tiger never contain white enamels, any creamy colour that does appear is from silver salts.

I've got a few cubes. No white enamel at all and none in a Tiger cube either.

I'm sure white and pink (and possibly even the orange and yellow) did not appear until after '75.

It wasn't just white that suddenly appeared.

I'm with Sue. The white/cream is unreacted silver chloride. I've just checked my cube

I have had some very interesting info from Jim Munnelly about early colours (pre Aug 76).

They had 4 colours molten in pots, 2 small ones for Dark Blue and Purple, a medium size for Light Blue and a large for clear for casing. The only 'cold colour' available (ie frit or other larger pieces of un-melted glass which was applied to a gather of glass) was 'traffic red' used for the 'Ming' range. "this looks black under the light blue casing.  Or brown against the light."

Also very interestingly the frigger fish with their unusual colours of white enamel, yellow and other colours, Jim thinks the Boffo's brought them from Whitefriars.

Hi,

I should have made it more clear that this thread was about general colours in 1976 rather than discussing the possibility of white.......

It is good to have the information from Jim Munnelly and I have had permission to show the vase from the Etsy link. The yellows must be chemically induced, something that I had not previously realized. 

Cheers,

Patrick.

The yellow comes from silver chloride, which starts off as a white powder, so not a cold colour rather a chemical reaction caused the heat

The traffic red would have been for Tortoiseshell (and any other bits containing brown). Silver nitrate turned red into brown. I wouldn't have been Ming. Ming is blue over yellow.
