cadmium colors in contact with lead based glasses

I'll start his with this simple observation: If anyone ever wondered why Cadmium yellows and reds turn a sort of ugly brown in contact with a lead based color, they do not like each other. Cad sels are not made using lead. Nominally, they're Zinc/Potash glasses. It's the main reason they are so intolerant of many clear glass bodies.

Further, any cadmium glasses in the presence of copper based colors, leaded or not will turn a really dirty brown as well.

Now do what you will with this board.
Where are we going and why am I in this basket?
