Slow drying on porous, dry bisque is the cause. The one on the top left was dipped for three seconds, and the ones on the top and bottom rights for five seconds. Thus, the thicker the application the worse this is. This is a base-coat dipping glaze, it has enough gum to slow down drying significantly, providing plenty of time for escaping air, displaced by the water being absorbed into this coarser particled clay body, to create these holes. The bottom left? Since these tiles are thick this enabled quickly dipping it into water first to dampen the bisque, then into the glaze. That solved the problem.
