Soap-ashes and potash were among the first commodities produced by the English in America. Potash was made from soap-ashes (wood ashes, especially those obtained from burning ash and elm) and was used at Jamestown for making both soap and glass. Soap-ashes were exported to England as early as 1608, and throughout the remainder of the century it appears that both potash and soap-ashes were shipped to the mother country, As early as 1621 soap-ashes were selling for six shillings to eight shillings per hundred weight, whereas potash was bringing between thirty-five shillings and forty shillings per hundred weight
