Oversprays on 3mm Clear Float: Spray A vs. Borax

When I use spray A on 3 mm clear float glass, it leaves a very slight haze in the top layer with a mottling effect from the spray pattern. I've tried applying different ways (airbrush, mouth sprayer, etc) and tried different drying periods, and also tin side down. I only see the haze when looking through the glass in stronger light.
Is anyone familiar with this? Way to correct it or the nature of the beast?
Thanks!

Three things to do: Get a good glass that doesn't scum up. Clean the glass well. Don't fire as hot. I never use overglaze. Kevin

Spray A has lead in it as well as a ground glass. Borax is a fluxing agent like lead, but wouldn't contain the glass particles. Switch to the borax and I expect your results will be better.

I don't use borax on glass 3/8" and thicker. I am led to understand that the thinner glasses aree more prone to devit because of the ease of certain molecules to rise to the surface. The thicker glasses hold that stuff inside.
When I do use borax, it comes out crystal clear on float. I did a round of sushi plates made of 2 layers of 3/16" with borax. They came out shiny and bright.
