Mer Almagroshares two Videos of the Enameling Technique of Grisalla with Opal Enamels.
Enjoy a clip from Mer Almagro’s video The Enameling Technique of Grisalla Opal, where Mer gives you a unique tutorial. I have seen Grisaille used with white opaque enamels over black opaque but her application using opals is just beautiful. After 30 years of enameling, you would think I had seen all the techniques. This is definitely a technique I will be using, I can see it helping me in my ocean scenes as well as in my animals. Her work is not only beautiful but also shows any enamelist a very delicate approach to shading your enamels.
In building a good foundation get to know your vitreous enamel flux.
Like any painting technique there are various primers for various jobs. In art of enameling we have quite a few fluxes but they produce various findings. You have heard of a car having the rust primer coat = flux, before the color coat, If you ever finish a beautiful wooden object you would have the sand and sealer = flux, before the varnish coat. And preparing metal to enamel is the same way. See how I have prepared an enamel flux test plate.
Enamels are reactive to metal, not all but 90% I would say. So flux coats are usually necessary, and there are several hardness of these fluxes from available manufactures.
