I don't unload the bisque (I fire at a community centre so the technicians load/unload) but do rinse after wet sanding and after that it's glove only handling until after they are glazed. I've had scrubbing damage the underglaze in the past so i only use a sponge now, but wet sand in one sink basin & rinse in the second basin.

As this issue is mostly on rims, I think it might be a moisture unevenness problem. Thanks for bringing this up. I'll watch the rims!

Some colors are grainy and need  Darvan periodically to apply smoothly. Yes I'm diligent about applying only on dry previous coats
