Cleaned cobalt blue Clarks Blood Mixture sparkles
There is something to be said for the beauty of a deep cobalt blue bottle. Maybe more than any other color cobalt glass improves visually with cleaning. Restoring the luster of cobalt glass with a light cleaning allows light to penetrate the glass. Light surging through antique cobalt glass makes it glow. The Glass Artisan would love to restore the luster of your cobalt bottles.
