A tared Gooch crucible is prepared by pouring a water suspension of asbestos fiber into the crucible and sucking it down to a pad thick enough to trap the sample particles on the filtering set-up. The crucible is then heated in a muffle furnace at 950 ± 50°C (1550 to 1750°F) for 30 min., cooled in a desiccator and weighed.
