George Brandt
Georg Brandt (26 June 1694 – 29 April 1768) was a Swedish chemist and mineralogist who discovered cobalt (c. 1735). He was the first person to discover a metal unknown in ancient times. He is also known for exposing fraudulent alchemists operating during his lifetime. Biography Brandt was born in Riddarhyttan, Skinnskatteberg parish, Västmanland to Jurgen Brandt, a mineowner and pharmacist, and Katarina Ysing. He was professor of chemistry at Uppsala University, and died in Stockholm. He was able to show that cobalt was the source of the blue color in glass, which previously had been attributed to the bismuth found with cobalt. He died on April 29, 1768, of prostate cancer. About 1741 he wrote: "As there are six kinds of metals, so I have also shown with reliable experiments... that there are also six kinds of half-metals: a new half-metal, namely Cobalt regulusRegulus: the more or less impure mass of metal formed beneath the slag during the smelting and reducing of ores.Me ...

Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). The red pigment vermilion is obtained by Mill (grinding), grinding natural cinnabar or synthetic mercuric sulfide. Mercury is used in ...

People From Skinnskatteberg Municipality
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Smalt
Cobalt glass—known as "smalt" when ground as a pigment—is a deep blue coloured glass prepared by including a cobalt compound, typically cobalt oxide or cobalt carbonate, in a glass melt. Cobalt is a very intense colouring agent and very little is required to show a noticeable amount of colour. Cobalt glass plates are used as an optical filter in flame tests to filter out the undesired strong yellow light emitted by traces of sodium, and expand the ability to see violet and blue hues, similar to didymium glass. Moderately ground cobalt glass (potassium cobalt silicate)—called "smalt"—has been historically important as a pigment in glassmaking, painting, pottery, for surface decoration of other types of glass and ceramics, and other media. The long history of its manufacture and use has been described comprehensively. Cobalt aluminate, also known as "cobalt blue", can be used in a similar way. Cobalt glass such as Bristol blue glass is appreciated for its attractive colour ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
