Just read the short article "adjusting glazes" by Pete Pinnell which someone recently was kind enough to provide a link. WOW! I can finally picture flocculation which previously was totally counterintuitive to me. A while back, I think it was on this forum when someone with a background in wastewater treatment gave the tip to add a flocculant to your throwing water so the water would clarify, inessence so the clay would separate out. Now that made total sense to me. Everybody else, of course was crying "foul!". Flocculation prevents settling!!!! It almost came to blows and eventually the opponents agreed to disagree.
OK, so now I can picture the little flocs of clay particles joining forces and in their strength in numbers, holding up the floating boulders the size of six story buildings...the non-clay portion of the glazes.
And it's easy to see that flocculation for waste water treatment makes sense because there are no boulders, just a lot of organic material that flocs together, gets heavy, and separates out. But that was always easy for me to see.
Definately a journey.
