Abstract
A method of making crucibles for flameless atomic spectroscopy comprises coating carbon crucible preforms with pyrolytic graphite in a reaction vessel by deposition of the graphite from a gas phase wherein the carbon crucible preforms are removed from the reaction vessel after cooling to room temperature and are re-introduced into the reaction vessel orientated in different positions before application of a second or subsequent coating to give a total thickness of the coatings of 20 to 80 .mu.m.
