Question: where did the saying dutch oven come from

title: Dutch oven
text: During the 17th century , brass was the preferred metal for English cookware and domestic utensiles , and the Dutch produced it at the lowest cost , which , however , was still expensive . In 1702 , Abraham Darby was a partner in the Brass Works Company of Bristol , which made malt mills for breweries . Apparently in 1704 , Darby visited the Netherlands , where he studied the Dutch methods of working brass , including the casting of brass pots . Darby learned that when making castings , the Dutch used molds made of sand rather than the traditional loam and clay , and this innovation produced a finer finish on their brassware . In 1706 he started a new brass mill in the Baptist Mills section of Bristol . There Darby realized that he could sell more kitchen wares if he could replace brass with a cheaper metal , namely , cast iron . Initial experiments to cast iron in sand molds were unsuccessful , but with the aid of one of his workers , James Thomas , a Welshman , he succeeded in casting iron cookware . In 1707 he obtained a patent for the process of casting iron in sand , which derived from the Dutch process . Thus the term `` Dutch oven '' has endured for over 300 years , since at least 1710 .
