Milk paint is a non-toxic water based mixture used as a paint. It is made from milk and lime with or without pigments added for color.[1][2][3] Borax may be added to the milk paint recipe to assist the lime in dissolving the casein and as a preservative.[4][5]
Though milk paint has been used for thousands of years it does not compete commercially with oil paints mostly due to its short shelf life.[6] Milk paint will spoil and must be used within a day or a little longer if refrigerated.[7]
Milk paint can be used to mimic the look of antique furniture.[8] Milk paint has also received renewed interest from the green building community. There are recipes for milk paint that are considered eco-conscious "safe", non-toxic, and "green" because they are made from natural materials plants and pigments.[9]
