I have not been happy about the results of using wadding to support the forms during glaze firing. The wadding has left marks that I cant file off, and although they may be hidden when the pieces are stacked, they extend surprisingly far and would be more visible if on the upper surface. My tests so far have been with relatively light pieces , so this problem is likely to be worse with the larger ones. As I wish to leave the construction flexible, allowing the purchaser to decide what order the pieces go on the stack, and which way up they prefer, I want to avoid any marks at all. Because the glaze does not appear to run (flux) at my cone 8 firing temperatures, and because I now incorporate a flat ring in my design, I may not need a prop to keep the glazed form off the kiln shelf. There is an alternative option, that of using a bisque fired stand. Here is an example I made whilst on an Annie Peaker course. Once the prop is covered in a generous layer of batt wash the supporting edges are not so sharp and the system will need testing with a real glaze firing
