More consistent color density. No shift in hue.

This style is not suitable for kilncasting because it can opalize (and turn a dense green/brown) and/or become incompatible when held at high temperatures for an extended period. It may also opalize and/or become incompatible in instances where processes exceed the parameters of the test for compatibility.  Testing recommended when heatwork exceeds these parameters.
