AMACO glazes are known for their rich colors, consistency, and versatility. Whether you’re a beginner or a seasoned ceramicist, AMACO offers a wide range of glaze lines that allow for both functional and artistic expression. This guide will help you understand how to get the most from these high-quality products.
What Makes AMACO Glazes Unique?
AMACO glazes deliver reliable results in both color and texture. They are formulated to work with different clay bodies and firing ranges, making them highly adaptable. Whether you want a soft celadon finish or bold, reactive textures, AMACO has a glaze for your project.
Overview of Popular AMACO Glaze Lines
Each AMACO glaze line offers something unique. Velvet Underglazes provide strong color and precision for detailed work. Potter’s Choice glazes are reactive and perfect for layering. Celadon glazes highlight textures, while Shino glazes offer rustic, earthy finishes.
Velvet Underglazes
Velvet Underglazes are ideal for brushwork, sgraffito, and layering. They can be used on greenware or bisque and covered with a clear glaze for added depth. Their smooth consistency allows for detailed linework and subtle shading in decorative ceramics.
Potter’s Choice Glazes
Potter’s Choice glazes are designed for mid-fire temperatures and are known for their beautiful, layered, and often unpredictable results. These glazes work especially well on textured pieces, where flowing effects and color variations can shine.
Celadon Series
The Celadon series includes transparent glazes that accentuate surface detail. They work best over textured or carved pieces, allowing fine lines and relief to show through. Their soft, glassy finish makes them popular for functional ware.
Shino & Special Effects Glazes
AMACO’s Shino glazes offer warm, earthy tones with variation based on application and firing. These glazes are great for rustic or traditional pieces. Some special effect glazes can also produce speckling, drips, or layered patterns when combined.
Application Techniques
AMACO glazes can be applied using brushing, dipping, spraying, or pouring. Brushing is great for small batches, while dipping provides an even coat. Spraying offers soft transitions, and pouring is ideal for creating movement and flow in the glaze.
Best Practices for Glazing
For best results, apply glazes evenly in 2–3 coats, letting each dry fully. Stir well before use to maintain a uniform consistency. Avoid over-application, which can cause running or blistering during firing. Test on sample tiles before glazing final pieces.
Firing Guidelines
Most AMACO glazes are formulated for mid-fire (Cone 5–6), though some work at low or high fire. Always check the label for firing range. Firing in an oxidation atmosphere (electric kiln) yields consistent results, while gas kilns may affect glaze behavior.
Clay Compatibility
AMACO glazes pair well with earthenware, stoneware, and porcelain clays. Some glazes, like Celadon, work best on light clays, while darker bodies enhance the depth of glazes like Shino. Always match glaze and clay for the desired visual effect.
Creative Project Ideas
Use Celadon on carved mugs, Velvet Underglazes for painted tiles, or layer Potter’s Choice glazes on textured bowls. Try combining Shino with a contrasting glaze for rustic effects. These glazes are perfect for exploring texture, layering, and color blending.
Common Mistakes to Avoid
Avoid applying glaze too thickly, which can cause running or cracking. Don’t skip test tiles—results can vary with kiln, clay, and application. Let layers dry fully and check firing temperature accuracy to prevent issues like pinholing or dull finishes.
AMACO glazes are powerful tools for ceramic artists who want vibrant color, surface interest, and consistent results. By learning their properties and experimenting with combinations, you can take your pottery to the next level. Explore, test, and create boldly.
