Cone 6 oxidation: Mirror Black creates a highly reflective, metallic black gloss finish. On some vertical surfaces and around surface textures, minor matte effects can be seen; all other applications result in the formation of a black, metallic mirror.
Cone 10 reduction (second image): Finish flattens. Color remains. Increased movement.
Tip: This glaze WILL move. Take care when using on vertical pieces – reduce glaze thickness towards the bottom third to minimize run-off.
Note: Not recommended for dinnerware due to surface durability.
