The glass here used to be clear before baking like the other flower you can see
WHY did some glass plate I painted turned milky when baking the paint?
So, I am making ForeverFlowers using vintage glass and plates. Some of my glass or even crystal I paint to add some colors.
Usually, I bake on the paint by placing the products into a cold oven, turning it to 350, and bake it for about 35 minutes after temperature is reached. I then turn off the oven and let my work cool down slowly in the oven.
One of my painted plates turned milky and I had to brush off some fine dust with a toothbrush. Still, it remains milky.
Could this be a lead crystal plate?
Any clue at all before putting my next batch to bake?
Much gratitude for suggestions.
