Releases between the Glass and the Dam

An alternative to fibre papers or kiln wash separators between the dam and the glass is to use iridised glass. This of course, only works on pieces with straight lines on the sides. If you place the iridised side toward the fibre paper, you will get a clean release with a minimum of texture. If you do decide to use iridised glass as the release, you must not use Thinfire. It will cause awful pitting in the iridised glass.
