The ashes and refuse withdrawn from the furnace and ashpit during the
progress of the test and at its close should be weighed so far as
possible in a dry state. If wet the amount of moisture should be
ascertained and allowed for, a sample being taken and dried for this
purpose. This sample may serve also for analysis and the determination
of unburned carbon and fusing temperature.
The method above described for sampling coal may also be followed for
obtaining a sample of the ashes and refuse.
