To say I'm new to enameling is an understatement as I just received my first shipment of vitreous enamels in the mail today and I am SO excited, can't wait to get started. I'm an experienced metalsmith, but can't resist jumping in head first on most new techniques I home school myself on. Is it possible to mix Transparent coloured enamels into an Opalescent white to achieve coloured opalescent enamel? Both of the enamels (Opalescent and Transparent) are leaded and have the same COE.

It would be better to layer your transparent color over the fired opalescent -
Glass does not mix into colors like watercolors or oil paints - you get a salt and pepper effect when mixing two colors together - but I would experiment with samples and see what kind of effects you can get by mixing your transparent into an opalescent and firing them together - You may come up with a great visual that you really like.
