Please log in for more thread options This will happen if the wash is applied too thickly. I sometimes wet sponge
the shelf before applying wash. Did you mix up the wash fresh or has it
been sitting? If it has been sitting then evaporation will might have made
it thicker. I put on a real thin coat, do the bisque fire with the shelves,
then apply another thin coat for the glaze fire. I never have been able to
get the shelves like I like them though.
