A dolly pot, also known as a dolly, is a portable tool used for crushing small quantities of gold-bearing rock, by hand, in a process known as dollying.
In principle, a dolly pot is somewhat like a large mortar and pestle, but is always made of metal and is intended specifically to crush hard rocks like quartz. It is typically flat at the bottom, rather than rounded as in a typical mortar.[2][3][4] 19th-century versions were often made of cast iron.[3] Modern dolly pots are typically fabricated from steel. The place of the pestle is taken by a long heavy steel rod, at one end provided with a stamping surface.[5][2][4]
The process of dollying is highly labour-intensive. It involves pulverising the rock, by hand, until the gold separates from the surrounding rock matrix. It typically is used only to test for the presence of gold in samples taken from a quartz reef.[6][4]
