A candle is a light source usually consisting of an internal wick which rises through the center of a column of solid fuel. Typically the fuel is some form of wax - paraffin wax being the most common. However in recent years new soy and vegetable candles have become popular.
Prior to the candle being ignited, the wick is saturated with the fuel in its solid form. The heat of the match or other flame being used to light the candle first melts and then vaporizes a small amount of the fuel. Once vaporized, the fuel combines with o ...

A rose is a flowering shrub of the genus Rosa and the flower of this shrub. There are more than a hundred species of wild roses, all from the northern hemisphere and mostly from temperate regions. The species form a group of generally thorny shrubs or climbers, and sometimes trailing plants, reaching 2-5 m tall, rarely reaching as high as 20 m by climbing over other plants.
The leaves of most species are 5-15 cm long, pinnate, with (3-) 5-9 (-13) leaflets and basal stipules; the leaflets ...
A helicopter is an aircraft which is lifted and propelled by one or more horizontal rotors (propellers). Helicopters are classified as rotary-wing aircraft to distinguish them from conventional fixed-wing aircraft. The word helicopter is derived from the Greek words helix (spiral) and pteron (wing). The engine-driven helicopter was invented by the Slovak inventor Jan Bahyl. The first stable, fully-controllable helicopter pl ...
Petroleum (from Greek petra – rock and oleum – oil), crude oil, sometimes colloquially called black gold, is a thick, dark brown or greenish liquid. A widely believed myth is that the oil itself is flammable; however, it is actually the gas that evaporates from the oil that is flammable. Petroleum exists in the upper strata of some areas of the Earth's crust. Another name is naphtha, from Persian naft or nafátá (to flow). It consists of a complex mixture of various hydrocarbons, l ...
Gasoline is a petroleum-derived liquid mixture consisting primarily of hydrocarbons, used as fuel in internal combustion engines.
Gasoline - Chemical analysis and production.
Gasoline is produced in oil refineries. These days, material that is simply separated from crude oil via distillation, called natural gasoline, will not meet the required specifications (in particular octane rating; see below) for modern engines, but these streams will form part of the blend.
The bulk of a typical gasoline consi ...
Oxy-fuel welding is a welding process commonly called oxyacetylene welding since acetylene is the predominant choice for a fuel, or often simply gas welding. A virtually identical procedure, with a different type of gas torch, a blowtorch, is used for cutting metal and called oxy-fuel cutting. In gas welding and cutting, the heat energy and high temperature needed to melt the metal is obtained by the combustion of a fuel gas with oxygen in a torch.

White spirit, also known as Stoddard solvent is a paraffin-derived clear, transparent liquid which is a common organic solvent used in painting and decorating.
It is a mixture of saturated aliphatic and alicyclic C7 to C12 hydrocarbons with a maximum content of 25% of C7 to C12 alkyl aromatic hydrocarbons.
White spirit is used as an extraction solvent, as a cleaning solvent, as a degreasing solvent and as a solvent in aerosols, paints, wood preservatives, lacquers, varnishes, and asphalt products. In western Europ ...
A clathrate or clathrate compound or cage compound is a chemical substance consisting of a lattice of one type of molecule trapping and containing a second type of molecule. (The word comes from the Greek klethra, meaning "bars" (in the sense of a lattice).) For example, a clathrate hydrate involves a special type of gas hydrate that consists of water molecules enclosing a trapped gas. Prospectors believe that compounds on the sea bed have trapped large amounts of methane in similar configurations. Researchers have begun to investigate silicon clathrates fo ...
Baron Dr. Carl (Karl) Ludwig von Reichenbach (February 12, 1788 - January 19, 1869) was a recognized chemist, metallurgist, naturalist and philosopher, a member of the prestigious Prussian Academy of Sciences. He is best known for his discoveries of kerosene (essential to rocket fuels), paraffin (a waxy solid added to many foods), and phenol (an antiseptic and anesthetic, used against sore throats).
He spent the last part of his life developing the now popular vitalist theory of the Odic force, the life principle which he belie ...
The word cheddite has these meanings:-
A class of explosive materials that were originally manufactured in the town of Chedde in Savoy, France in the early twentieth century. Closely related to Sprengel explosives, cheddites consisted of a high proportion of inorganic chlorates mixed with nitroaromatics (e.g. nitrobenzene or dinitrotoluene) plus a little paraffin or castor oil as a moderant for the chlorate. Several different types were made, and they were principally used in quarrying.
Since the 1970s, the comme
Wax play is a form of sensual play involving warm or hot wax usually dripped from candles or ladled onto a person's naked skin. Wax play may be combined with other BDSM or sexual activity.
Pure paraffin wax melts at around 130 to 135 degrees Fahrenheit (54 to 57 degrees Celsius). Adding stearine makes the wax harder and melt at a higher temperature. Adding mineral oil makes the wax softer and melt at a lower temperature.
Soft candles in glass jars usually have mineral oil in their blend and burn cooler at around 120 degrees Fahrenheit (49 degrees Celsius), Pillar candles are mostly paraffin and burn warmer at arou ...

A breast implant is a prosthesis used in cosmetic surgery to enlarge the size of a woman's breasts (known as breast augmentation) or to reconstruct the breast (for example, after a mastectomy, or during male-to-female sex reassignment surgery). There are four types of breast implant:
Saline-filled, which have a silicone shell filled with sterile saline liquid. These implants are currently the only type available in the United States, but future regulation may make more available.
Silic ...
Wax has traditionally referred to a substance that is secreted by bees (beeswax) and used by them in constructing their honeycombs.
In modern terms, wax is an imprecisely defined term generally understood to be a substance with properties similar to beeswax, namely
plastic (malleable) at normal ambient temperatures
a melting point above approximately 45 °C (which differentiates wa ...

Petroleum jelly or petrolatum is a byproduct of the refining of petroleum, made from the residue of petroleum distillation left in the still after all the oil has been vaporized.
Vaseline is a well-known brand of petroleum jelly originally produced by Chesebrough Manufacturing which merged with Pond's Extract Company in 1955 to form Chesebrough-Pond's, Inc. Unilever purchased Chesebrough-Pond's in 1987. Vaseline has become an example of generic brand name (genericized trademark) meaning Petroleum Jelly.

In the mid-19th century Baron Carl von Reichenbach, an accomplished chemist (known for his analysis of creosote, waxy paraffin, and phenol) gave the name Odic force (also called Od [õd] and Odyle) to a hypothetical vital energy or life force. Proponents of the concept suggest that Odic force permeates all living plants, animals, and humans. It took its place in the 19th century as one of many proto-scientific ideas leading towards a unified theory of vitalism. Von Reichenbach ...
