I am asking for suggestions for matte white underglazes or engobes. I would also consider making my own engobe out of my white stoneware clay body but I don't know how. I've never done that. I need it to be able to be painted on bisque ware under my Clear Bright from Laguna.
I have tried:
- Duncan Concepts white underglaze. It flares up and comes through the clear glaze. Yuck. That's not going to work.
- Dune White engobe from Laguna. If applied too thickly it forms micro cracks along the edges. Since this is filling in carving ....
I thought I would try Amaco's Velvet White but it says it is only food safe if I use it with their clear. I have extensively experimented with the Clear Bright and my clay bodies and I am not willing to change it.
I have been making a series of highly decorated pie plates with carving and slip inlay. I paint wax on a leather-hard piece and then carve through to the clay, then paint it with white stoneware slip.
The problem I am having is that the two most recent pieces I've made this way have been horribly pitted, tiny air bubbles formed when I painted on the slip and they did not show up until after it was fired. I thought I had them filled with the glaze but after glaze firing about 20 pits were still open, making a high-investment piece completely unusable.
I want to try just carving it plain and painting on/wiping off an underglaze or engobe after it is bisque fired.
This is not the item with the issues, this is another one that I made with the same technique.
