Tannic Acid is a light brown fluffy powder that darkens on exposure to sunlight and air. It is used to prestain woods that are low in tannin so that the chemical stains will be more effective. A solution is then applied to the wood with a rag or brush and allowed to dry. It can also be used to for rust prevention on iron.

Item well packaged and the 1lb comes in a nice durable HDPE as shown in the picture. Very fine even powdery consistency, smells a little bit like a wine barrel. Will order again
