Natural Dyes from Plants in Producing Colored Paste
Abstract:

Paste is a type of glue made from starch or dextrin, a starch product. This investigatory project shows that we can produce our own colored paste without spending much time and money and by performing simple steps. That’s why this Science Investigatory Project can help students save their money instead of spending it in buying expensive and commercialized colored glue. In addition, this colored paste can be an additional source of income.
