This is the latest test of my attempt to formulate a Nuka style glaze using #miscanthus ash instead of rice husk ash. . This was fired by @bandanapottery and their @penlandschool #woodfiring class in the second chamber of the #penlandschoolofcraft #woodkiln (thanks for letting me put these tests in!). . I’ve got a few other refinements to try, but I think this is usable, and from this test, I’m convinced that miscanthus ash is a totally viable biological source of silica. It isn’t as pure of a source of silica than rice hulls, but it comes close enough and brings its own character to a glaze. . Also learned in this firing is that the miscanthus seed stalks harvested in the fall contain the highest concentration of silica of all the different parts of the plants that I’ve harvested and tested so far. . #ceramics #naturalglazes #glazechemistry #ashglaze (at Penland School of Crafts) https://www.instagram.com/p/BzY7DZtHhtG/?igshid=1wkmw1rrx29b4
