Report dipping glaze leaves large bubbles on ware in Clay and Glaze Chemistry Posted October 2, 2011 Totally agree with Moz. Don't let those coats dry out. Big time bubbles = Posh Pet Bowls . I go for a long count on the dip and make notes about the count in my glazing journal for interesting combinations for future reference. I've had pleasing results from layering and so forth but only in "damp" time. Don't revisit dipping or spraying when ware is dry. Heartbreaking.
