The silicate fractions of stony meteorites show gallium / germanium ratios similar to those of tektites because they too have undergone melting at some point in their histories.

For some substances, auxiliary properties such as the melting point are given.

the physical property values include hardness, melting point, and specific gravity.

It is likely to have a much higher melting point than does iodine, on par with those of bismuth and polonium.

Unlike pure metals, most alloys do not have a single melting point, but a melting range in which the material is a mixture of solid and liquid phases.

However, for most alloys there is a particular proportion of constituents ( in rare cases two )— the eutectic mixture — which gives the alloy a unique melting point.

Ancient civilizations took into account the mixture and the various properties it produced, such as hardness, toughness and melting point, under various conditions of temperature and work hardening, developing much of the information contained in modern alloy constitution diagrams.

Classical methods ( also known as wet chemistry methods ) use separations such as precipitation, extraction, and distillation and qualitative analysis by color, odor, or melting point.

The relatively low melting point of brass ( 900 to 940 ° C, 1652 to 1724 ° F, depending on composition ) and its flow characteristics make it a relatively easy material to cast.

Since lead has a lower melting point than the other constituents of the brass, it tends to migrate towards the grain boundaries in the form of globules as it cools from casting.

The temperature of the phase transition is believed to be quite close to the melting point.

Paired DNA and RNA molecules are comparatively stable at room temperature but the two nucleotide strands will separate above a melting point that is determined by the length of the molecules, the extent of mispairing ( if any ), and the GC content.

Lists of the elements are available by name, by symbol, by atomic number, by density, by melting point, and by boiling point as well as ionization energies of the elements.

Since helium remains a liquid even at absolute zero at atmospheric pressure, it has only a boiling point, and not a melting point, in conventional presentations.

It is a steely-gray, lustrous, hard metal that takes a high polish and has a high melting point.

Iron is different from most other materials ( including bronze ), in that it does not immediately go from a solid to a liquid at its melting point.

The melting point of iron is much higher than that of bronze.

Smelting and melting of copper and its alloys such as leaded bronze were smelted in crucibles similar to those of the roman period which have thinner walls and flat bases to sit within the furnaces.

It was constructed by melting the bronze of the arms used by the Ejército de los Andes and inaugurated officially on March 13, 1904.

Reverberatory furnaces ( in this context, usually called air furnaces ) were formerly also used for melting brass, bronze, and pig iron for foundry work.

When attempting again, the melting furnace got overheated, spoiling the casting of the bronze.

The required temperature varies over a very large range, both in absolute terms, and in terms of the melting point of the base metal.

The melting temperature varies smoothly between the two endmembers, as do other properties.

The winter rains and the melting of the snow that accumulates on the Andes produce rivers whose flow varies with the seasons, but which carry water year round.

The practical melting point varies with different specimens, some being semi-fluid at the temperature of boiling water, others melting at 100 ° C to 120 ° C.

Basal melting results from geothermal heat flux out of the earth, which varies with location, as well as from friction heating which results from the ice moving over the surface below it.

The whole city is affected by the presence of groundwater, the level of which varies by up to a metre, being at its highest in spring due to snow melting in the mountains inland.

* Peanut M & M's, one of the best sellers, but relatively expensive and vulnerable to cracking and melting if temperature varies greatly.

The melting point of crystallized honey is between, depending on its composition.

Several other expressions for the estimated melting temperature can be obtained depending on the estimate of the average thermal energy.

It has a low melting point, around, depending on the exact mixture of metals.

The high concentration of power in a small volume of matter, which can be reached in this way results in very fast increase of temperature in the spot of impact causing the melting or even evaporation of any material, depending on working conditions.

For a brief period each year, the rays of the sun are warm enough to melt some of the snows piled a mile deep at the base of the headwalls, and then the pinnacles glisten in the daytime at high noon, and billions of gallons of water begin their slow seepage under the glaciers and across the rockstrewn hanging valleys on their long, meandering journey to the sea -- running east past the sky-carving massifs of Gurla Mandhata and Kemchenjunga, then turning south and curling down through the jungles of Assam, past the Khasi Hills, and into Bengal, past Sirinjani and Madaripur, until the hard water of the melting snows mingles with the soft drainage of fields and at length fans out to meld with the teeming salt depths of the Bay of Bengal.

Then he slipped and went down on his hands and knees in the melting snow.

Limitations on the lengths of these sequences diminish the stability of the comparatively short crystallites which can be formed, and this is reflected in a broadening of the melting range.

( Robert Chiang, J. B. Jackson, P. J. Flory ) Carefully executed melting studies on this system ( M. J. Richardson ) permit quantitative estimation of the instability engendered by reduced crystallite length.

In fact, the United States Mint, in anticipation of this practice, implemented new interim rules on December 14, 2006, subject to public comment for 30 days, which criminalized the melting and export of pennies and nickels.

Other reasons include: a ) changes in plant canopy caused by shifts in plant biomass production associated with moisture regime ; b ) changes in litter cover on the ground caused by changes in both plant residue decomposition rates driven by temperature and moisture dependent soil microbial activity as well as plant biomass production rates ; c ) changes in soil moisture due to shifting precipitation regimes and evapo-transpiration rates, which changes infiltration and runoff ratios ; d ) soil erodibility changes due to decrease in soil organic matter concentrations in soils that lead to a soil structure that is more susceptible to erosion and increased runoff due to increased soil surface sealing and crusting ; e ) a shift of winter precipitation from non-erosive snow to erosive rainfall due to increasing winter temperatures ; f ) melting of permafrost, which induces an erodible soil state from a previously non-erodible one ; and g ) shifts in land use made necessary to accommodate new climatic regimes.

He then re-calibrated his scale using the melting point of ice and normal human body temperature ( which were at 30 and 90 degrees ); he adjusted the scale so that the melting point of ice would be 32 degrees and body temperature 96 degrees, so that 64 intervals would separate the two, allowing him to mark degree lines on his instruments by simply bisecting the interval six times ( since 64 is 2 to the sixth power ).

Gelatin gels exist over only a small temperature range, the upper limit being the melting point of the gel, which depends on gelatin grade and concentration ( but is typically less than 35 ° C ) and the lower limit the freezing point at which ice crystallizes.

Above its melting point, however, water has little effect on viscosity.

His plays Han sidder ved Smeltediglen (" He sits by the melting pot ") and Niels Ebbesen were direct attacks on Nazism.

* In 1888, Friedrich Reinitzer ( 1858 – 1927 ) discovered the liquid crystalline nature of cholesterol extracted from carrots ( that is, two melting points and generation of colors ) and published his findings at a meeting of the Vienna Chemical Society on May 3, 1888 ( F. Reinitzer: Beiträge zur Kenntniss des Cholesterins, Monatshefte für Chemie ( Wien ) 9, 421 – 441 ( 1888 )).

The organisation created a new prototype bar in 1889 at the first General Conference on Weights and Measures ( CGPM: Conférence Générale des Poids et Mesures ), establishing the International Prototype Metre as the distance between two lines on a standard bar composed of an alloy of ninety percent platinum and ten percent iridium, measured at the melting point of ice.

The gram was first introduced in 1795, with a definition based on the density of water ( so that at the temperature of melting ice, one cubic centimeter of water would have a mass of one gram ; while the meter at the time was defined as the 10, 000, 000th part of the distance from the Earth's equator to the North Pole ).

In this approach melting of an amorphous material occurs when the broken bonds form a percolation cluster with T < sub > g </ sub > dependent on quasi-equilibrium thermodynamic parameters of bonds e. g. on enthalpy ( H < sub > d </ sub >) and entropy ( S < sub > d </ sub >) of formation of bonds in a given system at given conditions:
