One can produce a tar-like substance from corn stalks by heating them in a microwave oven. This process is known as pyrolysis. Tar is a dark brown or black viscous liquid of hydrocarbons and free carbon, obtained from a wide variety of organic materials through destructive distillation. Tar can be produced from coal, wood, petroleum, or peat. [1]
In October 1981, director Jonathan Demme presented the Made in Texas - New Films From Austin series at the Collective for Living Cinema in New York City. [1] He, along with Austin Film Society co-founder, South by South West co-founder, and Austin Chronicle co-founder Louis Black, assembled six 16mm and 8mm short films made in and around Austin, Texas, in 1980 to present as a representation of ...
Carbon black (Color Index International, PBK-7) is the name of a common black pigment, traditionally produced from charring organic materials such as wood or bone. It appears black because it reflects very little light in the visible part of the spectrum, with an albedo near zero. The actual albedo varies depending on the source material and ...
Tar paper is used as a roofing underlayment with asphalt, wood, shake, and other roof shingles as a form of intermediate bituminous waterproofing.It is sold in rolls of various widths, lengths, and thicknesses – 3-foot-wide (0.91 m) rolls, 50 or 100 feet (15 or 30 m) long and "15 lb" (7 kg) and "30 lb" (14 kg) weights are common in the U.S. – often marked with chalk lines at certain ...

Tuckpointing was a way of achieving a similar effect using cheap, unrubbed bricks; these were laid in a mortar of a matching colour (initially red, but later, blue-black bricks and mortar were occasionally used) and a fine fillet of white material, usually pipe clay or putty, pushed into the joints before the mortar set.

Birch bark tar use as an adhesive began in the Middle Paleolithic. Neanderthals produced tar through dry distillation of birch bark as early as 200,000 years ago. [6] A 2019 study demonstrated that birch bark tar production can be a simpler, more discoverable process by directly burning birch bark under overhanging stone surfaces in open-air conditions. [7]
Tar-like petroleum by-products can also be used for modern oakum. "White oakum" is made from untarred material, [ 1 ] and was chiefly used as packing between brick and masonry in homes and building construction prior to World War II , as its breathability allows moisture to continue to wick and transfer through the material.
