Clay pots are versatile and can be used for various purposes, including as planters or for cooking. When it comes to using clay pots as planters, non- toxic sealants and paints are available to protect the pots from water damage and to add color. Acrylic paint is a popular choice for DIYers, and ECOS and AFM paints are recommended for those who are chemically sensitive. Shellac is a natural wax that can be used for a shiny finish on the outside of the pot, but it is best suited for indoor use.
