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.
Vitreous Enamel Flux Comparison with what is on the market today. This test is showing flux enamels for silver and transparent enamels.
Enamels are reactive to metal, not all but 90% I would say. So flux coats on metal before enameling is usually necessary, and there are several hardness of these fluxes.
First, view my flux comparison test plate 1.
Here you have Ninomiya 3 Shippo 110, Vintage Thompson 757, Hirosawa S-1S and Soyer 3. These are all vitreous enamel flux, from different manufactures.I have fired at 1450 for 1 minute and as you can see all the flux has fused except the Soyer 3.
With another firing for 1.5 minutes you can see flux comparison plate 2 Soyer has fused.
Right! so Soyer 3 is the hardest firing flux.
Ideally we want our flux, in enameling, to keep the reactive enamels from touching the metal surface. If this is the toughest barrier why not use it!
There are other good products here, and some might use these brands of enamel flux, but when it comes to reds which are usually the most reactive enamel colors, it is the best barrier.
I have spent most of my enameling career as a cloisonne jewelry artist, and making cells to hole enamel can create different challenges that other enamel techniques.
Here are a couple of diagrams to explain.
Flux Fired Correctly
Over heating the jewel causes this..
Flux Over Fired
Cells contain more heat than open surface techniques of enameling. When enamels are over fired they travel to the hottest point, up the walls of cloison wires, lowering your base layer of protection = thinning the flux at the center point and what do you get?…Enamels the color of MUD.
Keep in mind #3 is flux for silver from most brands of vitreous enamels, Happy Enameling
