Using the Color Chart Effectively
The charter for using the Stroke and Coat color chart effectively involves considering several factors. First, remember that the colors on the chart are representations and may vary slightly from the fired results due to differences in kiln temperatures, clay body, and application techniques. It's always advisable to test the glazes on your specific clay and firing conditions before applying them to a final piece. Second, pay attention to the description of each color, noting its opacity, finish, and any special characteristics. Some colors are designed to be opaque, providing solid coverage, while others are more translucent and can be layered to create depth and dimension. Third, consider the number of coats recommended for each color. While one to three coats is generally sufficient, some colors may require more or fewer coats depending on the desired effect. Finally, explore the possibility of mixing colors to create custom hues, but always test the mixtures on a small sample before applying them to a larger project.
Troubleshooting Common Glazing Issues
Even with the user-friendly nature of Stroke and Coat glazes, some common glazing issues can arise. Understanding these issues and how to address them is crucial for achieving successful results. One common problem is crawling, where the glaze pulls away from certain areas of the piece during firing. This can be caused by applying the glaze too thickly, firing at too low a temperature, or having a dusty or oily surface on the bisque ware. To prevent crawling, apply the glaze in thin, even coats, ensure the kiln reaches the correct temperature, and thoroughly clean the bisque ware before glazing. Another issue is pinholing, which is the appearance of small holes in the glaze surface. This can be caused by the glaze being applied over underfired bisque, impurities in the clay, or gases escaping from the clay body during firing. To prevent pinholing, ensure the bisque ware is properly fired, use a clean clay body, and consider pre-firing the bisque to a slightly higher temperature. Blistering, crazing and shivering are other potential issues that may arise depending on the glaze combination and firing schedule utilized. The charter is to investigate and resolve each issue to ensure quality results.
Creative Techniques with Stroke and Coat
Stroke and Coat glazes are incredibly versatile and can be used with a variety of creative techniques to achieve unique effects. One popular technique is layering, where different colors are applied over each other to create depth and dimension. When layering, it's important to consider the opacity of each color and how they will interact with each other during firing. For example, a translucent color can be applied over an opaque color to create a subtle shimmer or gradient effect. Another technique is sgraffito, where a layer of glaze is applied and then scratched away to reveal the clay body underneath. This technique is perfect for creating intricate designs and patterns. Wax resist can also be used to create patterns and designs by preventing the glaze from adhering to certain areas of the piece. The charter is that experimentation is key to discovering new and exciting ways to use Stroke and Coat glazes.
Firing Considerations for Stroke and Coat
While Stroke and Coat glazes are designed to be user-friendly, understanding the firing process is crucial for achieving the best results. The recommended firing temperature for Stroke and Coat is cone 06, which is approximately 1830°F (999°C). However, many colors can also be fired at higher temperatures, expanding the possibilities for mixed-media and multi-firing techniques. It's important to follow the manufacturer's recommendations for firing temperatures and schedules to ensure that the glazes mature properly. When firing at higher temperatures, it's also important to test the glazes on a small sample to ensure that they don't run or blister. The charter for successful firing is to maintain a consistent and controlled temperature throughout the firing cycle and to allow the kiln to cool slowly to prevent thermal shock.
The Importance of Testing
As mentioned earlier, testing is an essential step in the glazing process, especially when using Stroke and Coat glazes for the first time or when experimenting with new techniques. Testing allows you to see how the glazes will look on your specific clay body and under your specific firing conditions. It also allows you to experiment with different application techniques and layering combinations. The charter for testing does not need to be elaborate. Simple test tiles can be created and glazed in a variety of ways to assess the final appearance of the glaze. These tiles should be labeled with the color names and application techniques used so that you can easily reference them later. Testing can save you time, money, and frustration by preventing unexpected results on your final pieces. Also, consider testing for food safety if you plan to use the finished piece for serving food.
Food Safety and Stroke and Coat
When creating functional pottery, food safety is a top concern. Stroke and Coat glazes are generally considered to be food-safe when fired according to the manufacturer's instructions. However, it's important to check the specific glaze you are using to ensure that it is labeled as food-safe. Some glazes may contain ingredients that are not safe for contact with food, especially if they are not fired to the correct temperature. Even if a glaze is labeled as food-safe, it's still important to test it for leaching. This can be done by soaking the fired piece in vinegar or lemon juice for 24 hours and then testing the liquid for lead or other heavy metals. The charter is, never use a glaze on a food surface if you are unsure of its safety. Choose glazes specifically designed for food contact, and always follow the manufacturer's instructions carefully.
Storage and Handling of Stroke and Coat Glazes
Proper storage and handling of Stroke and Coat glazes are essential for maintaining their quality and consistency. Glazes should be stored in a cool, dry place away from direct sunlight and extreme temperatures. The containers should be tightly sealed to prevent the glazes from drying out or becoming contaminated. Before using a glaze, it's important to stir it thoroughly to ensure that the pigments are evenly distributed. If the glaze has thickened, it can be thinned with a small amount of distilled water. However, be careful not to add too much water, as this can affect the glaze's opacity and firing characteristics. Always wear appropriate safety gear, such as gloves and a mask, when handling glazes to protect your skin and respiratory system. The charter is to clean up any spills immediately with a damp cloth to prevent staining. By following these storage and handling guidelines, you can ensure that your Stroke and Coat glazes remain in good condition for years to come. Properly label each glaze container to avoid confusion. Regularly check the consistency of the glazes, and discard any that have become contaminated or unusable.
Exploring Specialty Glazes and Finishes
Beyond the standard range of colors, Stroke and Coat offers a variety of specialty glazes and finishes that can add unique visual interest to your ceramic pieces. These include metallic glazes, which create a shiny, reflective surface; crystal glazes, which produce clusters of crystals during firing; and textured glazes, which add tactile dimension to the piece. When using specialty glazes, it's important to follow the manufacturer's instructions carefully, as they may require different firing temperatures or application techniques than standard glazes. For example, some metallic glazes may require multiple coats or a specific firing schedule to achieve the desired effect. Crystal glazes can be particularly sensitive to firing conditions, and even slight variations in temperature can affect the size and distribution of the crystals. The charter is to experiment with these specialty glazes to see how they interact with different clay bodies and firing conditions. Consider using them as accents or highlights to add visual interest to your pieces. Always test specialty glazes on a small sample before applying them to a larger project to avoid unexpected results. Examples of these finishes are iridescent, crackle and matte. These types of glazes can add additional interest to your ceramic pieces.
