Thallo is an emerald green super luster. Repeated brief reductions create a palette of exterior lusters; silvers, golds, blues and purples. It was developed from the popular test batches OX-459 and TO-578.
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 passed our compatibility and color tests, but not our pretty rod test.
