Calcium carbonate is also referred to as chalk. This dense, white powdery mineral is a common addition to the madder dye bath to deepen shades and is one of the principle minerals that create hard water. It may also be used with weld extract to bring out the bright, rich yellow shades. It is also used as a post-bath for mordanting cellulose fibers with aluminum acetate.
