AMACO Celadon C-01 Obsidian Black High Fire Transparent Gloss Glaze Pint, 16 oz. (473 mL), 100% Mixable Mid-High Fire Cone 5-6 (C) Liquid Ceramic Pottery Glaze for Bisque

Opaque Black glaze. Cone 5-6 glaze. Looks great on dark and light clay. Does the job. Love amaco glazes as they tend to be dependable and good quality.

Works beautifully! Fires great at cone 6.

This is my go-to for black glaze. 3 coats and the results are fantastic. Truly black.I’ve used this on 04 bisqueware fired to Cone5.It’s been so consistent, and I highly recommend this glaze. You won’t be disappointed.

I love the way this glaze combines with other colors!

I LOVE this glaze it turned out so beautiful and layers with other glazes nicely!

This is my favorite cone 6 black glaze. It's great for the frozen pond technique or the northern lights technique. Do not expect it to be as translucent as most celedons though. I'm surprised they even call it a celedon.

Amaco glaze is typically found in art stores. It is so handy to have it delivered that I wish that Amazon carried more colors.

Beautiful color glaze and worked as expected.
