Can anyone suggest a refractory material that works well with Shofu Vintage porcelain to fabricate feldspathic veneers?

Try using the refractouty material made by Vita for feldspathic porcelain. Personally, I prefer using Palladium foil (.001) there is absolute color control with it. I burnish the foil onto the master model using a regular pencil eraser. It works like a charm. I remove thr foil after glazing and etch and ship in saline All the best results.
