Ideal for artists seeking to add a celestial, otherworldly finish to their pottery without complex firing protocols. ## Description It's out of this world! AMACO Cosmos CO-08 Dark Star Gloss Glaze is a fluid, dark matte glaze with iridescent crystals like a beetle shell that breaks translucent. Apply 4 coats to Cone 04 bisque, then fire to Cone 5-6; glaze performs best at Cone 6 but can be fired to Cone 5. 16 oz. (473 mL) jar. Iridescent mid-high fire (Cone 5-6) AMACO Cosmos Crystalline "CO" Glazes exhibit unique and captivating visual effects reminiscent of cosmic or otherworldly phenomena. They're meticulously crafted to capture the mesmerizing beauty of crystalline glazes in every brushstroke, right out of the jar. Transform your pottery into celestial masterpieces that sparkle with the brilliance of distant galaxies. Crystals will develop on both horizontal and vertical clay surfaces; vertical surfaces will encourage running. These glazes can be fired in a normal medium-speed firing with no special cooling schedule required. To take this glaze to the next level, use a controlled cooling scheduled for increased crystal growth. For best results, leave inside or back of form unglazed to avoid pinholing; if glazing a piece all the way to the end of the foot, use a drip tray to protect kiln shelves. Not recommended for surfaces which come into contact with food and drink due to durability. Review: Blick is the most reliable seller of glazes I have found, 10 out of 10! - Beautiful glaze, but it does leak and can get tiny bubbles or small creases (usually not much more than a few). I fire to cone 6 and have used this on black, white and brown clays, the result varies by clay colour and body, the most similar to the picture is on Smooth white clay (low grog). (If you do not like holes in things do not watch the clip (apparently some people get all kids of bothered πŸ€·β€β™€οΈ)) Review: Quick delivery! - The glaze I wanted. Perfect transaction!

Perfect transaction! Thank you. ### ⭐⭐ Color changing *by P***R on July 13, 2025* Turned all my ceramic pieces shades of yellow. No matter what temperature I fired at, whether I did it with no other glazes, or as an over glaze, no matter what. Did not have the pearlescent it was supposed to. Occasionally I’d see a few β€œcrystals” but it was mostly just yellow. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/670342478-amaco-cosmos-crystalline-gloss-glaze-16-oz-473-ml-co](https://www.desertcart.co.za/products/670342478-amaco-cosmos-crystalline-gloss-glaze-16-oz-473-ml-co) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-09*
