It creates unique cosmic visual effects with crystals forming on all surfaces, requires 4 coats on Cone 04 bisque, and fires with standard medium-speed schedules. Ideal for artists seeking to add a celestial, otherworldly finish to their pottery, it pairs perfectly with AMACO Velvet Underglazes and demands careful kiln handling to avoid pinholing. ## Description It's out of this world! 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. Apply 4 coats to Cone 04 bisque, then fire to Cone 5-6. 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. 16 oz. (473 mL) jar. 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 🤷‍♀️)) Review: Quick delivery! - The glaze I wanted. Perfect transaction! Thank you. ## Features - Iridescent mid-high fire (Cone 5-6) AMACO Cosmos Crystalline "CO" Glazes exhibit unique and captivating visual effects reminiscent of cosmic or otherworldly phenomena; meticulously crafted to capture the mesmerizing beauty of crystalline glazes in every brushstroke, right out of the jar. - Apply 4 coats to Cone 04 bisque, then fire to Cone 5-6. - Crystals will develop on both horizontal and vertical clay surfaces; vertical surfaces will encourage running. - Normal medium-speed firing with no special cooling schedule required; use a controlled cooling scheduled for increased crystal growth. - 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. - Supernova layers nicely with AMACO Velvet Underglazes. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DKTW58MB | | Best Sellers Rank | #69,027 in Arts, Crafts & Sewing ( See Top 100 in Arts, Crafts & Sewing ) #121 in Ceramics Glazes | | Customer Reviews | 4.4 4.4 out of 5 stars (20) | | Date First Available | December 14, 2023 | | Item Weight | 1.76 pounds | | Item model number | 35550A | | Manufacturer | Amaco | | Product Dimensions | 3.25 x 3.25 x 5.5 inches | ## Images ![AMACO Cosmos Crystalline "CO" Gloss Glazes - Image 1](https://m.media-amazon.com/images/I/51Ot5d1k5PL.jpg) ![AMACO Cosmos Crystalline "CO" Gloss Glazes - Image 2](https://m.media-amazon.com/images/I/51NTgo70AjL.jpg) ![AMACO Cosmos Crystalline "CO" Gloss Glazes - Image 3](https://m.media-amazon.com/images/I/51Q0VmsPasL.jpg) ![AMACO Cosmos Crystalline "CO" Gloss Glazes - Image 4](https://m.media-amazon.com/images/I/610vKWD9ylL.jpg) ![AMACO Cosmos Crystalline "CO" Gloss Glazes - Image 5](https://m.media-amazon.com/images/I/61xqNTzAirL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Blick is the most reliable seller of glazes I have found, 10 out of 10! *by K***G on July 22, 2025* Beautiful glaze, but it does leak and can get tiny bubbles or small creases (usually not much more than a few).

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 “crystals” but it was mostly just yellow. ## Frequently Bought Together - Amaco Cosmos Glaze - CO-6 Supernova, 16 oz - Amaco Cosmos Glaze - CO-8 Dark Star, 16 oz - Pasler Gold Glaze for Ceramic Pottery Bisque,PCG01,16fl oz/473ml --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.uy/products/670342479-amaco-cosmos-crystalline-co-gloss-glazes](https://www.desertcart.uy/products/670342479-amaco-cosmos-crystalline-co-gloss-glazes) --- *Product available on Desertcart Uruguay* *Store origin: UY* *Last updated: 2026-04-23*
