Hi Lily, I think you might've missed the first part of my post: < I=92ve been reading about the solubility issues associated with some commonly used glaze ingredients (such as Gerstley Borate, Neph Sy and Lithium Carb) that causes some glazes to deteriorate over time. My own experience seems to prove this out as well, especially with a couple of my favorite raku glazes. Thus the idea of fresh-mixing my glazes makes sense, or more practically, weighing out larger batches of the dry ingredients, and mixing small amounts with water as needed.>> I have no problem mixing & twice-sieving my glazes once they=92re mixed with= water, even ball-milling some of them. My intent is to have small batches of FRESH glazes on hand to use as needed without having to weigh out recipes from scratch each time - not my favorite use of time. Just so you know, I=92m a 15 year potter, my studio is on our farm south of Spokane. I like to think I'm professional, but I=92m not a production potter, so vast quantities of glazes such as Michael or David or Craig use are not needed. These days, my passion revolves around with raku firing, including naked raku & Emu feathers, shard pots, fuming (Kosai) & multiple layering/ multiple firings. So you can be assured, my respirator cartridges/filters are well-used and up-to-date. I DO heed your safety warnings and appreciate that you=92re looking out for the uninformed & beginners, as we all were at one time. And I love your suggestion of sieving into an unconnected sink, since I just happen to have one! Always looking for an easier (as well as more efficient & safe) way=85 Thanks for your thoughts & concern, Lezlie
