Milk Glass Sapphire Blue Art Glass Cullet Manganese Glowing Swirl Slag #4GX80

Milk Glass Sapphire Blue Art Glass Cullet Manganese Glowing Swirl Slag #4GX80 UV reactive photo is taken with a 365 nm UV light in a dark photography box. Please note that manganese will NOT glow under a 395nm light - a 365nm light is requred for manganese. My art glass cullet is remnants from old glass factories throughout the Midwest. The chunked glass is from the process of clean out of the glass after a production run. These pieces are very unique in color and pattern due to the unusual mix of glass that might have been cleaned out of multiple runs of different colors. Much, but not all, of my glass is from the Fenton factory. Each piece is unique. Please see photos for measurements. Grid scale in photo is one inch by one inch and meant as an rough size measurement. The piece of natural shaped cullet in the photo is the exact piece you will receive. Please be aware that cullet can have sharp edges.
