<p>[QUOTE="James Conrad, post: 422116, member: 5066"]Early 18th century hardware was cast from molten brass using molds made of sand. This type of hardware is easy to recognize because it often has “inclusions” from the sand itself in the brass, either grains of sand or odd colors from impurities. The backs of this type of hardware were often left with the impression of the sand while the faces were polished. Around the middle of the 18th century the customary blend of copper and zinc was changed to include more copper, giving the alloy more of a reddish cast than the pale yellow brass used for hardware earlier in the century. And by 1780, rolled brass sheets were available so that each piece of hardware could be cut or stamped rather than having to be cast. This greatly reduced the cost and increased the availability and uniformity of late 18th century drawer pulls and escutcheons.</p><p><br /></p><p>The use of high pressure rollers during the Federal period increased output even more. No longer did decorative pulls have to be engraved or chased individually. The designs were rolled right into the brass itself.
