Today, the term is used to describe steel that mimics the appearance and performance of Damascus steel, usually that which is produced by either crucible forging or pattern welding.

Today the traditional crucible steel is seldom used, but the high carbon steel is usually tool steel or stainless steel.

In this setup, the sensitivity of the calorimeter is not affected by the crucible, the type of purgegas, or the flow rate.

However, due to a combination of relatively poor sensitivity, slower than normal scan rates ( typically 2-3 °/ min-due to much heavier crucible ) and unknonwn activation energy, it is necessary to deduct about 75-100 ° C from the initial start of the observed exotherm to suggest a maximum temperature for the material.

* 3rd century BC – Wootz steel, the first crucible steel, is invented in ancient India

The RAE's emblem is a fiery crucible, and its motto is "" (" cleans, sets, and casts splendour ").

The Soviet-perfected skull crucible is still used today, with little variation.

However, due to a combination of relatively poor sensitivity, slower than normal scan rates ( typically 2-3 °/ min-due to much heavier crucible ) and unknown activation energy, it is necessary to deduct about 75-100 ° C from the initial start of the observed exotherm to suggest a maximum temperature for the material.

High-purity, semiconductor-grade silicon ( only a few parts per million of impurities ) is melted in a crucible, usually made of quartz.

When silicon is grown by the Czochralski method, the melt is contained in a silica ( quartz ) crucible.

A crucible is a container that can withstand very high temperatures and is used for metal, glass, and pigment production as well as a number of modern laboratory processes.

The crucible design is similar to the smelting and melting crucibles of the period utilizing the same material as the smelting and melting crucibles.

The crucible with the sample and lid is allowed to cool in a desiccator.

The crucible and lid with the sample inside is weighed very accurately again only after it has completely cooled to room temperature ( higher temperature would cause air currents around the balance giving inaccurate results ).

The mass of the empty, pre-weighed crucible and lid is subtracted from this result to yield the mass of the completely dried residue in the crucible.

A crucible with a bottom perforated with small holes which is designed specifically for use in filtration, especially for gravimetric analysis as just described, is called a Gooch crucible after its inventor, Frank Austen Gooch.

#* Depending on the procedure followed, the filter might be a piece of ashless filter paper in a fluted funnel, or a filter crucible.

Rhazes refuted Aristotle's theory of four classical elements for the first time and set up the firm foundations of modern chemistry, using the laboratory in the modern sense, designing and describing more than twenty instruments, many parts of which are still in use today, such as a crucible, cucurbit or retort for distillation, and the head of a still with a delivery tube ( ambiq, Latin alembic ), and various types of furnace or stove.

Unlike the wire gauze, which primarily supports glassware such as a beaker, laboratory flasks, or an evaporating basin, the pipeclay triangle normally supports a crucible.

Whilst working at the Plessey Company laboratory ( in a disused church ) in Towcester, UK, Redfern received a glassy carbon crucible for duplication from UKAEA.

This technique involved molten zirconia being contained within a thin shell of still-solid zirconia, with crystal growth from the melt: The process was named cold crucible, an allusion to the system of water cooling used.

In the eighteenth and nineteenth century, the metaphor of a " crucible " or "( s ) melting pot " was used to describe the fusion of different nationalities, ethnicities and cultures.

A modern crucible used in the production of silicon ingots via the Czochralski process

The form of the crucibles has varied through time, with designs reflecting the process for which they are used, as well as regional variation. The crucible helps to prevent the heat from affecting the solution.

However, no charcoal was used within the crucible.

The crucible and lid to be used are pre-weighed very accurately on an analytical balance.

Since the mass of every crucible and lid is different, the pre-firing / pre-weighing must be done for every new crucible / lid used.

A crucible can be similarly used to determine the percentage of ash contained in an otherwise burnable sample of material such as coal, wood, or oil.

Various methods were used to produce crucible steel.

* A cementation furnace might be used to convert the bar iron ( if it was pure enough ) into blister steel by the cementation process, either as an end in itself or as the raw material for crucible steel.

Gooch invented the Gooch crucible, which is used, for example, to determine the solubility of bituminous materials such as road tars and petroleum asphalts.

Note: FLiNaK is almost pure white when crystallized, the black pecks and waves in this image are likely from graphite or SiC from the crucible used to melt the salt.

The use of oxygen in the growth environment is reported to suppress gallium loss from the melt ; however, too high an oxygen level can lead to platinum ( crucible material used for the melt ) dissolution in the melt.

At the fin de siècle, when Vienna was a major crucible and center for modern arts and culture, Altenberg was a very influential part of a literary and artistic movement known as Jung Wien or " Young Vienna ".

Merv was a notable centre from the production of crucible steel from the ninth century AD, when Islamic scholar, al-Kindi ( AD 801-866 ) referred to the region of Khorasan as producing steel.

He discovered the Czochralski method in 1916, when he accidentally dipped his pen into a crucible of molten tin rather than his inkwell.

Of the songwriters on the Greenwich Village scene of the 1960s, Dave Van Ronk said, " Dylan is usually cited as the founder of the new song movement, and he certainly became its most visible standard-bearer, but the person who started the whole thing was Tom Paxton ... he tested his songs in the crucible of live performance, he found that his own stuff was getting more attention than when he was singing traditional songs or stuff by other people ... he set himself a training regimen of deliberately writing one song every day.

Something ferocious and tragic, like what happened to Jericho or the cities of the plain-something terrible I mean, son, so that when the people have been through hellfire and the crucible, and have suffered agony enough and grief, they ’ ll be people again, human beings, not a bunch of smug contented cows rooting at the trough.

Worker monitoring melting zirconium oxide and yttrium oxide in an induction heated " cold crucible " to create cubic zirconia.

The crucible changed into rounded or pointed bottom vessels with a more conical shape ; these were heated from below, unlike prehistoric types which were irregular in shape and were heated from above.

After some possible washing and / or pre-drying of this filtrate, the residue on the filter paper can be placed in the crucible and fired ( heated at very high temperature ) until all the volatiles and moisture are driven out of the sample residue in the crucible.

In this process, wrought iron and cast iron may be heated together in a crucible to produce steel by fusion.

# After filtration, the precipitate – including the filter paper or crucible – is heated.

The precipitate can be carefully heated in a crucible until the filter paper has burned away ; this leaves only the precipitate.

TVA discharges can be ignited in high vacuum conditions between a heated cathode ( electron gun ) and an anode ( tungsten crucible ) containing the material.

A crucible is a heat-resistant container in which materials can be heated to very high temperatures.

A small amount of metal in a crucible ( a sort of ceramic pan ) next to the mold is heated with a torch.

The oxide was heated with aluminium in a crucible in a furnace.
