I want to paint on above counter sinks that I have found at the big box stores like Home Depot, Lowes, etc.
I used to paint on old sinks that I found at Habitat for Humanity and I used cone 06 glazes. I would paint on top of the old glaze, using 06 underglazes and glazes and then I would put a lead based clear glaze. It would be fired at cone 06. They came out beautifully.
I know that lead has been taken out of many of the glazes now and I don't know if that is what made it work before. I tried to paint on a sink I bought at Lowes with the same glazes and cone temp. All the glaze cracked off of the sink. Very disappointing to say the least.
Does anyone have any knowledge about what commercial sinks might use for glaze? Could it be that it is a cone 6 glaze or higher?
I just want to find the right glazes to paint on new sinks.
Thanks so much
