We have had an incredibly fun time formulating and testing these glazes to provide you with the most accurate performance data. However, results may vary based on individual application methods and firing techniques. We encourage you to create your own test pieces specific to your own practices to create a visual reference highlighting your unique process. We recommend a normal cooling cycle across all colors to ensure consistent results.
