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]
Tar is occasionally referred to as an acronym for total aerosol residue, [3] a backronym coined in the mid-1960s. [4] Tar, when in the lungs, coats the cilia causing them to stop working and eventually die, causing conditions such as lung cancer as the toxic particles in tobacco smoke are no longer trapped by the cilia but enter the alveoli ...

"Bananas are great because they're easy to digest and considered non-irritating for the stomach and upper gastrointestinal tract," says Julie Upton, M.S., R.D., co-founder of Appetite for Health.
In the 1990s, coal tar was discovered in Greenville's Newtown neighborhood. While the state takes on years of cleanup, residents want to be involved.
Pine tar is a form of wood tar produced by the high temperature carbonization of pine wood in anoxic conditions (dry distillation or destructive distillation). The wood is rapidly decomposed by applying heat and pressure in a closed container; the primary resulting products are charcoal and pine tar .
Unsurprisingly, hard red winter wheat has a higher gluten content than soft winter wheat, making it likely harder to digest for all us gluten-sensitives out there.
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]
