The thumping noise you hear is my head against my wedging table.
So first I switched underglazes from closed down local co. to Amaco. Then I switched to a new clear cover glaze. Most recent is Laguna Morraccan Sand MSD-29. I had called Laguna and asked specifically for a clear glaze to cover under glaze. This is the glaze that was recommended. I first did a test tile. Colors looked good. Well, the tiles were all flat. When I did some mishima on a bowl with the underglaze it ran. I have used this underglaze on several other items. Flat items are OK. Vertical runs. I will do a round of test tiles next glaze firing but hoping for some suggestions. Crappy cell phone pic attached for your enjoyment.
Well, verizon is holding my pic hostage. I will post it when there is free space on the inter web.
