How do you make glaze at home for a pottery project that will not harm any one?

To make a safe, non-toxic glaze at home for pottery, you can use a mixture of food-safe ingredients. Combine 1 part clay, 1 part silica, and 1 part feldspar, then add water until you achieve a smooth, pourable consistency. For color, incorporate natural oxides like iron oxide or copper carbonate in small amounts. Always test your glaze on a small piece before applying it to your final project to ensure safety and desired results.
