Thanks, again... As much as I hate to admit it, these mugs need to be redone! I’m glad you helped me see that.

Thank you, Min. I did sand it, but it's not just on the surface. So, could I use my clay body mixed with frit, in a thick application to try to cover? I've done hours of work on these and hate to start over if there might be a fix...

I had a problem with a ^04 bisque fire yesterday and need some help, please. I used a "magic" recipe ( dry clay, vinegar & toilet paper) to build up a couple of greenware areas after sgraffito; I've done this before with good results. The most recent bisque'd pieces have some darker areas now where I did repairs on bare clay and I'm guessing the slip got contaminated during the process. I'd like to cover the dark areas with a slip or engobe of the same clay body for glazing, in hopes I can hide these areas. I thought that if I used my clay body for this, it might not be a good fit on

Underglazes contain flux. They flux at different temperatures, depending on the color of the underglaze, so I avoid putting underglaze on any area that will be touching the kiln shelf (or touching any other part of the piece, like the flange of a lid) - it will probably stick, When I make a bowl without a foot ring, I leave a circle on the bottom where it will touch the shelf. For the glaze firing, I wax that same circle and clean off any glaze that might end up there. If you’ve already applied underglaze to that area, you can use one or more kiln stilts to support the bowl and keep it o

The work is wonderful! Yay! I'd suggest that you take a look at Amaco's website because they have samples of how the glazes will look, before and after firing. So do most other commercial glaze makers. The two you've chosen probably will be perfect. But, beware! There's nothing that's fool-proof about ceramics! Good luck and have fun!

I've had the same problem and still do sometimes. The bubbles on my work looked just like yours. Although there were suggestions about needing a longer bisque for outgassing, I did 12 hr bisques (elec) and that didn't help. Certain underglaze colors produced the bubbles more consistently than others. I spoke with a chemist at Amaco who couldn't resolve it for me. What finally made a difference for me was changing the commercial underglazes and glaze I use, from Amaco to Mayco. Perhaps an incompatibility with the clay I use? I don't know if that info will help...
