Occurrences in the United States were known as early as 1698 with numerous finds along Brandywine Creek in Pennsylvania (Frondel, 1988). The celebrated purse made from asbestos that Benjamin Franklin took to London in 1724, and which now resides in the British Museum of Natural History, may have been made of long-fiber asbestos from Newbury, Massachusetts. As a journeyman printer, Franklin made paper from asbestos, as did many Europeans. It was also used in making lamp wicks and cloth. Commercial mining in the United States took place some time after the first discovery of asbestos on Staten Island, New York, in 1818. (Asbestos continued to be mined at the site until 1876.) By 1825 more than seventy localities were known to produce asbestos in the United States (Robinson, 1825). However, as early as 1804 Jameson had recorded the mineralogy of the species and listed the numerous university, societal, and private mineral collections containing specimens of asbestos from U.S. localities and asbestos products of local manufacture. 

Asbestos has been known and used for over 2000 years. Egyptians used asbestos cloth to prepare bodies for burial. The Romans called it aminatus and used it as a cremation cloth and for lamp wicks. Marco Polo described its use in the preparation of fire-resistant textiles in the... 

Asdestas,—This matorial is of frequent use in the laboratory, and in the manufacture of various articles destined to resist the action of fire, such as lamp-wicks, et cetera. Annexed is its composition t—... 

We see capillary action at work in many phenomena. If a paintbrush is dipped into water, the water rises into the narrow spaces between the bristles by capillary action. Hang your hair in the bathtub, and water seeps up to your scalp in the same way. This is how oil moves up a lamp wick and how water moves up a bath towel when one end hangs in water. Dip one end of a lump of sugar in coffee, and the entire lump is quickly wet. The capillary action occurring between soil particles is important in bringing water to the roots of plants. 

To Make Quick Match. Quick match is made by immersing lamp-wick in a solution of saltpetre with meal powder, winding it on a frame, and afterwards dusting with meal powder. To 28 ounces cotton, take saltpetre, I pound alcohol, 2 quarts water, 3 quarts solution of isinglass (1 ounce to the... 

The properties of asbestos have been known for thousands of years, with one of the earliest recorded uses of asbestos being by Finnish Potters who used it to strengthen their clay over 4000 years ago. It is also recorded that the Egyptians and Romans shrouded their dead in asbestos cloth, and the Greeks and Romans made asbestos lamp wicks that apparently seemed to burn forever.

The best form of lamp, shown in Rg. 10, may be made by obtaining a small glass kerosene hand lamp, which will cost only a trifle of two or three shillings.. Cut off that portion of the burner above the screw, where it is held to the socket that is fastened to the lamp. Remove the tube that holds the lamp wick and also the little contrivance made to raise and lower the wick. In the place where the tube was inserted, generally a fiat one, file out with a round... 

Capillary movement in porous solids. When granular and porous solids such as clays, sand, soil, paint pigments, and minerals are being dried, unbound or free moisture moves through the capillaries and voids of the solids by capillary action, not by diffusion. This mechanism, involving surface tension, is similar to the movement of oil in a lamp wick.
