Results:
All tiles had Licorice dipped onto the tile first, one time.
The second glaze was dipped over the Licorice Glaze, twice.
Licorice and Rhodes Rutile
Overlap is a white and blue fur, not fluid, but streaking. =20
Licorice and MC6G Spearmint
Overlap is very similar to Floating Blue. Not fluid, but can feel a =
thickness difference=20
where glaze line of second glaze ends.
Many nuances in the fur including Cobalt blue, green and tan.
Licorice and MC6G Raspberry
Slight change of color from Black to Browner, but still very dark. =
Overall surface of overlap is glossier than
Licorice alone.
Licorice and Hal's Pale Apple
The overlap shows tiny crystals that are pale in color, giving a more =
mat surface than the Licorice alone.
Where these two glazes break, the ground is pale with dark blue fur.
Licorice and MC6G Waxwing
The overlap is as glossy as the two glazes by themselves. There is not =
a large color distinction, as the overlap is very dark.
There are traces of blues throughout the overlap. It creates a fur =
under a gloss shell.

the darker Licorice where it
breaks. Strong contrasts.
The MC6G Spearmint and the Rutile overlaps give the strongest contrasts =
