AG-19 "Issenburg's" Glaze is 50% wood ash, 50% Red Art; Wood Ash Hot Tips

AG-19 "Issenburg's" Glaze is 50% wood ash, 50% Red Art; Phil Rogers made an excellent suggestion to at least once-wash the ash because it can be screened nicely as a watery solution. The ash settles in a day or 2, and you have a nice by-product of lye water. Separate the two and let the ash dry to a fine powder and its ready for use and/or storage. The bucket of glaze made with washed ash will not gradually thicken as it otherwise would, which can lead to application problems if the wet glaze is stored over time.
