TAG-44 Green X is very unusual! Green X is a blue rod, but it shifts to a dense dark transparent green in the kiln. Green X can also strike with a bloom of a hazy pale blue, and this is especially noticeable under encasement.
The photo shows Green X after being worked in an oxidizing flame then cooled until the orange glow was gone and reheated in the outer portion of the oxidizing flame until a hazy blue appeared.
Rods are approximately 8mm in diameter and 19 inches long. Approximately 10 rods per pound. Sample half rods are 9 inches long.
