Calcium Carbonate is also known as chalk. It is a common assistant to harden water and hence deepen the colour of natural dyes such as madder and weld. It is also used to fix an al uminum acetate mordant or a ferrous mordant. Available in different sizes in either a reusable/recyclable plastic container or reusable plastic bag. Our rates reflect a growing discount as the size increases. Show more
