The ash samples are usually fused with lithium tetraborate or lithium metaborate in a platinum crucible by heating in a muffle furnace to 950C. The ash extract obtained by dissolution in nitric acid, is analysed by atomic absorption spectometry in the presence of an ionization suppressant (Standards Association of Australia, 1981).

The Ash test result is expressed as % ash. A magnified optical examination of the ash residue is performed to determine if the ash is glass, mineral, or a combination of both. The total ash content equals the weight of the ash divided by the weight of the original sample multiplied by 100%. Six grams of sample is typically used, which ...
