However, you cannot rush the application when working on a living and breathing human being. Once mixed, the alginate has to be applied quickly as it comes with a short set time. This will be accurate and when mixed properly, will yield the right texture and consistency. If you want to get the proportions right, you have to weigh the alginate prior to adding it to the mixing container. Therefore, mixing 3 cups of water to 1 cup of alginate can play havoc with the consistency of the alginate mix – it may turn out too runny or even too thick which in turn affects the application and quality of the body mold.

When in doubt about the water quality use distilled water (available from most grocery stores) or at the very least bottled water. If the water has too much mineral content the alginate may not set at all. Hard water will cause lumpiness like cottage cheese.
