Making underglazes from powders in Clay and Glaze Chemistry Posted August 25, 2018 · Edited August 25, 2018 by yappystudent · Report reply Speaking of Amaco Velvets, I noticed their "Bright Red" was literally the brightest most reliably intense medium red I've managed to find. I used up my small jar, and was going to replace it, but it was $15 or more than the same size Duncans (still pretty good, not the same though) and passed them up at my local store with some disappointment. Also they only had it in pints of course, whereas everything else was available in small sizes. I resent being gouged which also figured into my choices. I'd still like to use it for tiny dots and such, but forget anything else.
