Stoneware matte glazes range from solid shades to those that create interesting color variations as they move and break. Application thickness is the key to making mattes work for you.
The choice of clay body, thickness of glaze application, firing process and temperature will affect the fired finish.
Cone 5/6 to cone 10.
General Appearance of Wrought Iron
Cone 6: An intermittent, dappled black gloss-matte finish that is reminiscent of high-fire oil-spot glazes. Typically, oil-spot glazes are thickly applied and require some reduction during the firing to achieve the oil-matte effects; Wrought Iron does the job with just two coats in a cone 6 oxidation firing.
Cone 10: Color changes to a dark metallic gray.
- This glaze is not completely matte but will have a matte finish with variation of gloss.
- The thinner the application, the browner the glaze; the thicker the application, the blacker the glaze.
- Due to its high manganese content, there is a chance of bubbling on a speckled clay body.
- Always test prior to use.
