Editing Pyrometric cone (section)

== History ==
In 1782, [[Josiah Wedgwood]] created accurately scaled pyrometric device, with details published in the Philosophical Transactions of the Royal Society of London in 1782 (Vol. LXXII, part 2). This led him to be elected a fellow of the [[Royal Society]].<ref>{{cite web | url=https://collection.sciencemuseumgroup.org.uk/objects/co532892/wedgwood-pyrometer-by-j-newman-1827-56-pyrometer | title=Wedgwood Pyrometer by J.

The modern form of the pyrometric cone was developed by [[Hermann Seger]] and first used to control the firing of porcelain wares at the [[Royal Porcelain Factory, Berlin]] (''Königliche Porzellanmanufaktur'', in 1886, where Seger was director.<ref>{{cite journal|last=Lange|first=P.|title=Role of August Hermann Seger in the development of silicate technology.|journal=Ceram.

Pyrometric cones are often referred to as ''Orton Cones'' within the [[United States]], but in his lifetime Orton preferred calling them ''Seger cones''.<ref>{{cite journal |last1=Gorton |first1=Elmer |title=Remarks on Seger Cones |journal=Clay Record |date=November 15, 1900 |volume=17 |page=15 |url=https://books.googleusercontent.com/books/content?req=AKW5QacScdBi4xFRbgFo6wvsyQXfs5vwRouNfUpuHC8u601IYoOgrctyWtZ-O1HrEX7P1Urbv7B7rvr7iCC5CLLNouAsIWuWKwtGGHcVt-BTDiWlgWsR69Cbs7_3T6lRKZeqOe38msoryq0zA9OQ58F-JGa7U9KU2iShb-WeBgYd2RgvjjglPcbmfEQVZBjYaqPynhMy4DLspPm2rsXcRYVYN-y9kpmbgdaWkKvqzKpeNKmlksFMFDeAqwAmtIy0-ls4b0LjLflV}}</ref>

|text=I hope no one will ever apply my name to the cone system in any way, because Dr. Seger deserves all the glory which there is in having brought us this most convenient system. My cones are labeled ''Standard pyrometric cones''. I have hesitated to print the term ''Seger cones'' on my output because the German cone makers...might feel I was attempting to cut under or defraud them...The name ''Seger cone'' will then become a sort of monument to that prominent man, who must always be recognized as the first scientific ceramist of all history.|author=Edward Orton Jr.
