1864 Daedalus "Daedalus" were obtained by astronomers Tom Gehrels, Petr Pravec and Brian Warner. Lightcurve analysis gave a concurring rotation period of 8.572 hours with a high brightness variation of 0.85–1.04 magnitude, indicating a non-spheroidal shape (). This minor planet was named after the Greek mythological figure Daedalus, the builder of King Minos labyrinth, who was subsequently imprisoned there with his son Icarus. They escaped on wings of feathers and wax, but whereas Icarus was drowned when the wax in his wings melted, Daedalus went on to Sicily and built there a temple to Apollo. There is also a lunar crater called
Technological and industrial history of the United States only be made once, silversmiths generally used lost-wax casting, in which a sculpted object was carved out of wax, an investment casting was made, and the wax was melted away. The molds produced in this manner could only be used once, which made them inconvenient for standard objects like handles and buckles. Permanent mold casting, an industrial casting technique focused on high-volume production, allowed smiths to reuse molds to make exact replicas of the most commonly used items they sold. In creating these molds and developing standardized manufacturing processes, silversmiths could begin delegating some work to apprentices and journeymen. For
