这个支架是由一种被称为失蜡技术的复杂金属加工方法制成的。想要的图像是用蜡雕刻的，周围是粘土，烘烤后会硬化成模具。当模具被烧制时，蜡被熔化并"丢失"，留下一个与蜡图像相对应的负空间。然后将熔化的金属倒入空腔中，以形成原始蜡模型的复制品。

This stand was made by a sophisticated method of metalwork known as the lost-wax technique. The desired image was sculpted in wax and surrounded with clay that hardened into a mold when baked. When the mold was fired, the wax was melted and "lost," leaving a negative space that corresponded to the wax image. Molten metal was then poured into the cavity to form a reproduction of the original wax model.
