Understanding Pottery Glaze
The Importance of Glazing
Glazing serves several essential purposes in pottery:
Sealing: Glaze creates a watertight barrier on the surface, making pottery functional for holding liquids.
Enhancing Appearance: Glazes add color, texture, and shine to pottery, making it visually appealing.
Protecting: Glaze protects the underlying clay from stains, scratches, and wear.
Types of Glazes
There are various types of glazes, including:
Transparent Glazes: These glazes allow the clay's natural color to show through while adding a glossy finish.
For example: MS - 29 Clear Bright
Opaque Glazes: Opaque glazes cover the clay's color entirely, creating a solid, often vibrant, surface.
Textured Glazes: These glazes add depth and dimension to your pottery, creating unique tactile experiences.
Preparing Your Pottery
Before you start glazing, your pottery needs proper preparation.
Bisque Firing
Bisque firing is the initial firing of your pottery before glazing. It removes moisture and makes the clay more porous, allowing it to absorb glaze effectively.
Cleaning and Sanding
Ensure your pottery is clean and free of dust or debris. Sanding the surface lightly will create a smoother glaze application.
You can use our sponges and polishing pads for cleaning and sanding.
Choosing the Right Glaze
Consider the firing temperature and type of clay you're using when selecting a glaze. Some glazes are specifically formulated for high-temperature firing, while others are suitable for lower temperatures.
High Temperature Glazes (Cone 10)
Mid - High Temperature Glazes (Cone:5/6)
Low Temperature Glazes (Cone:06)
Color and Texture
Think about the aesthetic you want to achieve. Glazes come in a wide range of colors and textures, allowing for endless creative possibilities.
Applying Glaze
Brushing glaze is a common method, especially for intricate designs. Use soft brushes to apply glaze evenly.
Dipping
Dipping involves immersing your pottery into a container of glaze. It's an efficient way to achieve consistent coverage.
Spraying
Spraying glaze creates a fine mist, resulting in a smooth and even finish.
Glazing Techniques
Layering Glazes
Experiment with layering different glazes to create unique and complex color combinations.
Using Wax Resist
Applying wax to specific areas before glazing can create interesting patterns by preventing the glaze from adhering to those spots.
Firing Your Pottery
Kiln Settings
Follow the recommended firing schedule for your chosen glaze. Pay attention to temperature and firing duration.
You can also read our kiln schedule blog post.
Cooling Process
After firing, allow your pottery to cool slowly in the kiln to prevent thermal shock.
Troubleshooting Glazing Issues
Pinholing
Small holes in the glaze surface can be caused by trapped air or impurities. Properly preparing your pottery can help prevent pinholing.

Crawling
Crawling is when the glaze pulls away from the clay, leaving exposed areas. Ensure your pottery is clean and free of contaminants before glazing.
Uneven Coverage
Inconsistent glaze coverage may result from uneven application. Take your time to apply glaze evenly and avoid overloading.
Glazing Safety Tips
Ventilation
Always work in a well-ventilated area to avoid inhaling glaze fumes.
Protective Gear
Wear appropriate safety gear, including gloves and a mask, when handling glaze materials. Also you can wear a Pottery Apron.
Caring for Glazed Pottery
Properly cared for glazed pottery can last a lifetime. Wash it gently by hand or in the dishwasher if it's food-safe, and avoid exposing it to extreme temperatures.
Conclusion
Mastering the art of glazing pottery takes practice and experimentation. By understanding the different types of glazes, applying them effectively, and troubleshooting common issues, you can create pottery that's both beautiful and functional.
