Paraffin candle. Paraffin wax (or petroleum wax) is a soft colorless solid derived from petroleum, coal, or oil shale that consists of a mixture of hydrocarbon molecules containing between 20 and 40 carbon atoms. It is solid at room temperature and begins to melt above approximately 37 °C (99 °F), [2] and its boiling point is above 370 °C ...
A major component of beeswax is myricyl palmitate which is an ester of triacontanol and palmitic acid. Its melting point is 62–65 °C (144–149 °F). Spermaceti occurs in large amounts in the head oil of the sperm whale. One of its main constituents is cetyl palmitate, another ester of a fatty acid and a fatty alcohol.
Hentriacontane, also called untriacontane, is a solid, long-chain alkane hydrocarbon with the structural formula CH 3 (CH 2) 29 CH 3.It is the main component of paraffin wax.. It is found in a variety of plants, including peas (Pisum sativum), Acacia senegal, Gymnema sylvestre and others, and also comprises about 8–9% of beeswax.
Petroleum jelly is a mixture of hydrocarbons, with a melting point that depends on the exact proportions. The melting point is typically between 40 and 70 °C (105 and 160 °F). [8] [9] It is flammable only when heated to liquid; then the fumes will light, not the liquid itself, so a wick material is needed to ignite petroleum jelly.
Microcrystalline waxes can generally be put into two categories: "laminating" grades and "hardening" grades. The laminating grades typically have a melting point of 140–175 F (60 – 80 °C) and needle penetration of 25 or above. The hardening grades will range from about 175–200 F (80 – 93 °C), and have a needle penetration of 25 or below.
The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
Iosif Kotek and Pyotr Ilyich Tchaikovsky. The Valse-Scherzo in C major, Op. 34, TH 58, is a work for violin and orchestra by Pyotr Ilyich Tchaikovsky, written in 1877.. It is not to be confused with two similarly named works by Tchaikovsky, both for solo piano: one written in 1870 as Op. 7, [1] and one from 1889 without opus number.
Beeswax candles which commonly melt at around 62-65 °C (unsafe for wax play). [6] [7] [8] [4] Microcrystalline wax which commonly melts at around 63-93 °C (unsafe for wax play). [9] Stearin which commonly melts at around 80 °C (unsafe for wax play). [10] Candle additives such as dye, oils, and scents may increase the melting point.
