Cone 6 oxidation: Crackle Matte Clear is a soft matte, semi-transparent glaze that develops a fine crackle pattern.
Cone 10 reduction: No Change.
TIP: A minimum of two coats are needed to develop a crackle pattern. To highlight the crackle pattern, after firing, wipe black acrylic or ink over the ware and wipe off, allowing the ink to fill the cracks.
