Description
A nonflowering, grass-like plant of the genus Equisetum, such as Equisetum hyemale, found in wet, swampy soil. In medieval times, horsetail was imported from Holland. It was called Dutch rush and used for cleaning pots and burnishing Metal. Horsetail stems contain fine-grain Silica with small angular fingers. They are used as an Abrasive for polishing Veneer, burnishing Clay, and smoothing Gesso grounds.
