A test to deduce the amount of ash forming material present in a petroleum product so as to decide it's use in certain applications. Ash-forming materials are considered to be undesirable impurities or contaminants.
The specimen is placed in a suitable vessel, evaporating dish or crucible and ignited. It is allowed to burn until only ash and carbon remains. The carbonaceous residue is reduced to ash by heating in a muffle Furnace at about 775oC, cooled and weighed. A furnace is a device for heating air or any other fluid. ...
Ashing is also performed prior to chemical analysis by Inductively Coupled Plasma Emission Spectrometry ICPES.
The Ashesurn is reputed to contain a burnt set of bails symbolising the death of English cricket.
In the 1990s, given Australia's long dominance of the Ashes series, and the by now universal acceptance of the Darnley urn as ‘The Ashes’, the idea was mooted that the victorious team in an Ashes series should be awarded the urn as a trophy and allowed to retain it until the next series.
Although this won England the Ashes, it caused such a furore in Australia that diplomats had to intervene to prevent serious harm to Anglo-Australian relations, and the MCC eventually changed the laws of cricket to prevent anyone from using the tactic again.
The 2005Ashes series was that year's edition of the long-standing and storied cricket rivalry between England and Australia.
However, with the Ashes going to Australia in the event of a drawn series, there was still all to play for at The Oval.
The final match to decide the fate of the legendary Ashesurn finally began, and the proverbial first blood was drawn by England as Michael Vaughan won his third toss of the series (much to the delight of the Brit Oval crowd).
