An enhanced formula of Kronos that is stronger, cleaner, and easier to strike. When worked in a slightly reducing flame this color develops swirls of blue, green, cream and a rainbow iridesence. Briefly reheating in a oxygen rich flame can enhance struck color. This glass is a deep cobalt blue.
Our second quality rods are less than perfect in shape. They may be too large, too small, too short, chipped, twisted or have an inclusion. They have all passed both our compatibility test and our color test, just not our pretty rod test.
