This article is about the test in petroleum manufacturing. For the semiconductor manufacturing process, see plasma ashing.
Ashing is a test to deduce the amount of ash forming material present in a petroleum product so as to decide its 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.
Ashing is also performed prior to chemical analysis by inductively coupled plasma emission spectrometry.

- Robust nanogap electrodes for nanodevices with a separation of 3.0 ± 1.7 nm were simultaneously mass-produced at a yield of 90% by a combination of electron beam lithography (EBL) and electroless gold plating (EGP). Nanogap electrodes demonstrated their robustness as they maintained their structure
