These ingredients are essential for achieving professional results, drawing from ancient pottery traditions to modern techniques. We recommend sourcing high-quality materials to ensure consistency and safety during firing.
Below, we list the key ingredients for a basic Cone 10 glaze recipe, ordered by their typical sequence in preparation. We’ve bolded Cone 10 for emphasis, as it’s our core keyword, and used italics for important terms like oxides or fluxes to highlight their roles.
- Feldspar (6 cups ground): As a primary flux, this helps lower the melting point for Cone 10 firing. We suggest using potash feldspar for better glaze flow; grind it finely if not pre-processed.
- Silica (4 cups powdered): The main glass-former that provides the glossy texture in Cone 10 glazes. Ensure it’s pure silica sand, sifted to remove any large particles for even mixing.
- Kaolin (2 cups): Acts as a suspension agent to prevent settling; this plastic clay adds body to the glaze slurry. Use calcined kaolin for reduced shrinkage during high-heat applications.
- Ball Clay (1 cup): Provides plasticity and helps with glaze adhesion. We prefer a fine-mesh ball clay to avoid lumps when combining with other dry ingredients.
- Iron Oxide (0.5 cups for color variation): A common colorant that produces earthy tones; adjust amounts for desired shades in Cone 10 recipes. Wear gloves when handling to prevent skin contact.
- Cobalt Oxide (0.1 cups for blue hues): Delivers intense blue colors under Cone 10 conditions; this transition metal oxide is potent, so measure precisely with a digital scale.
- Water (as needed, approximately 4-6 cups): Used to create the slurry; add distilled water gradually until the mixture reaches a creamy consistency suitable for application.
For precise measurements and variations, refer to the following table comparing common Cone 10 glaze ingredients and their firing effects:

Instructions
Now that we have gathered our essential ingredients and equipment, we guide you through the precise steps to create and fire Cone 10 ceramic glazes for durable and glossy finishes. Follow these instructions carefully to achieve professional-quality results in your projects.
Preparing Ingredients
Before mixing, we prepare our ingredients to ensure accuracy and consistency in the final glaze. Start by measuring each component as listed in our earlier ingredients section—using a digital scale for precision—to avoid any variations that could affect firing outcomes.
- Weigh the dry ingredients first: Place your bowl on the scale and tare it. Add feldspar (300 grams), silica (200 grams), kaolin (100 grams), and ball clay (50 grams) one at a time, double-checking measurements to maintain the recipe’s balance.
- Incorporate colorants: Measure out iron oxide (10 grams) and cobalt oxide (5 grams) into separate small containers, as these pigments create vibrant reds and blues when fired at Cone 10.
- Add water: Measure 500 milliliters of distilled water, which helps achieve the right slurry consistency without introducing impurities that might cause defects.
- Grind if necessary: If any dry ingredients appear clumpy, use a mortar and pestle to grind them finely, ensuring even distribution for a smooth glaze texture.
This preparation step is crucial for preventing inconsistencies, allowing the glaze to fuse perfectly during high-heat firing.
Mixing the Glaze
Once ingredients are prepared, we mix the glaze to form a uniform slurry that coats ceramics evenly and produces glossy, durable surfaces. Use a stainless-steel bowl and stirring tool for this process to avoid contamination.
Follow these steps for optimal results:
- Combine dry ingredients: Pour the weighed feldspar, silica, kaolin, ball clay, iron oxide, and cobalt oxide into the mixing bowl. Stir gently to blend, creating a fine powder base that ensures even color dispersion.
- Add water gradually: Slowly pour in the distilled water while stirring continuously with a sturdy tool. Aim for a creamy, lump-free consistency—similar to thick paint—that clings to your stirring utensil without dripping excessively.
- Mix thoroughly: Use a drill with a mixing attachment for larger batches, stirring for at least 5 minutes until the mixture is homogeneous. Check for any undissolved particles, as these could lead to pitting in the fired glaze.
- Test the viscosity: Dip a tool into the mixture and lift it; the glaze should form ribbons that slowly dissolve back in, indicating it’s ready for application.
Remember, proper mixing enhances the glaze’s adhesion and firing performance, transforming raw materials into a vibrant, textured finish.
Applying the Glaze
With the glaze mixed to perfection, we apply it to your ceramic pieces using techniques that ensure even coverage and maximize the high-fire gloss of Cone 10 results. Work in a well-ventilated area with your prepared tools for the best outcome.
Here’s how to proceed:
- Prepare your pieces: Clean the bisque-fired ceramics thoroughly to remove dust, then choose your method—brushing for detailed work or dipping for full coverage.
- Brush application: Dip a soft-bristle brush into the glaze and apply thin, even coats to the surface, starting from the top and working down. Use 2-3 layers for depth, allowing each to dry for 10-15 minutes to prevent runs.
- Dipping method: Submerge the piece fully into the glaze slurry for 5-10 seconds, then lift and let excess drip off. Rotate the piece to ensure uniform coating, achieving a smooth, professional look.
- Handle with care: Avoid over-application, as thick layers can cause cracking during firing. For textured effects, use a sponge or spray for subtle variations.
This step brings your vision to life, setting the stage for the transformation that occurs in the kiln.
