Painting on glass blocks
I painted a design by Renee Mullins on an 8 in glass block. It looked great til I put the lights in and turned them on. The painting shows the unevenness of the paint because it is not ompletely opaque. Streaking and darker spots where shading was done. What am I doing wrong? I used Americana paints. Is there something I can add to the paint. I did etch the glass first. Appreciate any help you or anyone can provide.
