Duncan SY1026 Modern Brass Metallic Glaze for Ceramics, 4 oz Jar -Fires to Cone 06

Good glaze

I bought this glaze, hoping that it would look like shiny, golden brass. The listing said that it fired to Cone 06. That was just what I wanted. When I got the jar, it said "Fire to Shelf Cone 04." When I asked the seller which directions were correct, the answer I got was "test it." Well, I did. It turned glossy black at Cone 06. Not what I wanted. Please have your listings checked to be sure the information is correct. It does make a difference.
