Note: All raw materials are measured up or down to the nearest half
decimal. Colorants or additives to a 100 gram batch are measured in percent
to the 100 gram batch.
Results:
Gloss, tenmoku brown black over all surface. Streaking throughout, a lot of
movement. Moved, but did not drip off of test tile. High contrasting
mustard gold clusters of small crystals throughout surface. Will observe
for shivering due to higher amount of Lithium Carb.
