PC- 11 Blue Spark
Blue Spark is a specialty glaze that can give dramatic metallic crystalline results when used correctly. Below find suggestions for the best results.
​
HOW IT WORKS:
Blue Spark is a glossy, royal blue glaze which develops small triangular dark gray metallic crystals that make this glaze look like lapis lazuli. This opaque glaze does not break over texture. For best results apply three even brush coats.
LET'S FIGURE OUT WHAT'S WRONG.
STILL NOT GETTING ACCURATE RESULTS? LET'S TALK BISQUE
#1 APPLICATION
Thickness of application can affect the appearance of the metallic glaze. If the glaze is translucent or dark with no crystal growth it may be too thin.
#2 BISQUE TEMPERATURE
The temperature to which your ware was bisqued can have an affect on the final piece. We recommend a bisque between cone 08 and cone 03, though a bisque as low as cone 010 will work.
LETS TALK CLAY BODIES
#3 CLAY BODY
The metallics do best on a clay body that isn’t fully vitrified in the glaze firing. Clay body color doesn’t seem to make a difference.
