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. These crucibles in some cases have thinner walls and have more refractory properties Tylecote During the Roman period a new process of metalworking started, cementation , used in the production of brass. This process involves the combination of a metal and a gas to produce an alloy Zwicker et al.

Brass is made by mixing solid copper metal with zinc oxide or carbonate which comes in the form of calamine or smithsonite Rehren This reaction has to take place in a part-closed or closed container otherwise the zinc vapour would escape before it can react with the copper.

Cementation crucibles therefore have a lid or cap which limits the amount of gas loss from the crucible. 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 conical shape and small mouth allowed the lid to be added. Cementation vessels are mass-produced due to crucibles having to be broken open to remove the brass once the reaction has finished as in most cases the lid would have baked hard to the vessel or the brass might have adhered to the vessel walls.

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. The technology for this type of smelting started to change at the end of the Medieval period with the introduction of new tempering material for the ceramic crucibles.

Some of these copper alloy crucibles were used in the making of bells. These later medieval crucibles were a more mass-produced product. The cementation process, which was lost from the end of the Roman to the early Medieval period, continued in the same way with brass. Brass production increased during the medieval period due to a better understanding of the technology behind it. Furthermore, the process for carrying out cementation for brass did not change greatly until the 19th century.

However, during this period a vast and highly important technological innovation happened using the cementation process, the production of crucible steel. Steel production using iron and carbon works similarly to brass, with the iron metal being mixed with carbon to produce steel. The first examples of cementation steel is wootz steel from India Craddock However, no charcoal was used within the crucible.

These early crucibles would only produce a small amount of steel as they would have to be broken once the process has finished. By the late Medieval period steel production had moved from India to modern-day Uzbekistan where new materials were being used in the production of steel crucibles, for example Mullite crucibles were introduced. At the end of the Medieval and into the Post Medieval new types of crucible designs and processes started.

Smelting and melting crucibles types started to become more limited in designs which are produced by a few specialists. The main types used during the Post Medieval period are the Hessian Crucibles which were made in the Hesse region in Germany. These are triangular vessels made on a wheel or within a mould using high alumina clay and tempered with pure quartz sand.

These had a very similar design to that of the triangular crucibles from Hesse but they also occur in conical forms. These crucibles were traded all across Europe and the New World. The refining of methods during the Medieval and Post Medieval periods led to the invention of the cupel which resembles a small egg cup, made of ceramic or bone ash which was used to separate base metals from noble metals.

This process is known as cupellation. Cupellation started long before the Post Medieval period, however the first vessels made to carry out this process started in the 16th Century Rehren Another vessel used for the same process is a scorifier which is similar to a cupel but slightly larger and removes the lead and leaves the noble metals behind.

Cupels and scorifiers were mass-produced as after each reduction the vessels would have absorbed all of the lead and become fully saturated. These vessels were also used in the process of Metallurgical Assay where the noble metals are removed from a coin or a weight of metal to determine the amount of the noble metals within the object. Crucible are used in the laboratory to contain chemical compounds when heated to extremely high temperatures.

Crucibles are available in several sizes and typically come with a correspondingly-sized lid. When heated over a flame, the crucible is often held inside a pipeclay triangle which itself is held on top of a tripod. Crucibles and their covers are made of high temperature-resistant materials, usually porcelain , alumina or an inert metal.

One of the earliest uses of platinum was to make crucibles. Ceramics such as alumina , zirconia , and especially magnesia will tolerate the highest temperatures. More recently, metals such as nickel and zirconium have been used.

The lids are typically loose-fitting to allow gases to escape during heating of a sample inside. Crucibles and their lids can come in high form and low form shapes and in various sizes, but rather small 10—15 ml size porcelain crucibles are commonly used for gravimetric chemical analysis. These small size crucibles and their covers made of porcelain are quite cheap when sold in quantity to laboratories, and the crucibles are sometimes disposed of after use in precise quantitative chemical analysis.

There is usually a large mark-up when they are sold individually in hobby shops.

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. While crucibles historically were usually made from clay, [1] they can be made from any material that withstands temperatures high enough to melt or otherwise alter its contents. The Crucible by Arthur Miller was a very admirable way to portray the Salem Witch Trials. This is a topic suggestion on The Crucible from Paper Masters.
