Wax jack-Wax jack-The wax jack was first introduced in 1700. Before that time a simple taper was used in a loose ball. Despite the resemblance to a candle, they were not used for illumination. Although common in England and Europe, they were not used much in North America.Most early wax jacks were worked by silversmith... | milkshake721/2.1M-wiki-STEM |
Wax jack-Description-A wax jack was a vertical or horizontal shaft around which a thin beeswax taper was coiled. The top end protruded through a hole in a pan that had a pincer to hold the taper in place. This allowed the taper to be lit and the resulting puddle of wax easily controlled.

Torus-Torus-In geometry, a torus (PL: tori or toruses) is a surface of revolution generated by revolving a circle in three-dimensional space one full revolution about an axis that is coplanar with the circle. The main types of toruses include ring toruses, horn toruses, and spindle toruses. A ring torus is sometimes co... | milkshake721/2.1M-wiki-STEM |
Torus-Torus-If the axis of revolution does not touch the circle, the surface has a ring shape and is called a torus of revolution, also known as a ring torus. If the axis of revolution is tangent to the circle, the surface is a horn torus. If the axis of revolution passes twice through the circle, the surface is a spin... | milkshake721/2.1M-wiki-STEM |
