Calx

When making an indigo vat, you require three things: the indigo extract, an alkali, and a reducing agent. Calcium hydroxide is a very common alkali, used in several types of vats, including Fructose, Iron and Henna vats. It is a food safe ingredient, also known as pickling lime, used in processes such as pickling and tortilla making. Use with indigo and a reducing agent to create a vat and create blue! If you are new to indigo dyeing, you may want to begin with our Indigo Kit , which has the pre-measured quantities of each ingredient that you need, as well as comprehensive instructions.
