Determination of Ash


1.1 Platinum Dish — Having a capacity of 100 mL.


2.1 Heat the platinum dish to redness, cool to room temperature in a dessicator and weigh.

2.2 Take about 5 g of the material in a watch-glass and weigh accurately.

2.3 Transfer about three-quarters of this quantity to the platinum dish and heat on a Bunsen burner so that the material burns gently at the surface. When about half of the material is burnt away, stop heating, cool and add the remainder of the material.

2.4 Weigh the watch-glass again an find, by difference, the exact mass of the sample transferred to the platinum dish.

2.5 Heat again as before till the material is completely charred.

2.6 Incinerate in a muffle furnace at 550 ºC to 650 ºC for 1 hour.

2.7 Cool to room temperature in a dessicator and weigh.

2.8 Repeat incineration, cooling and weighing until the difference between two successive weighing is less than one milligram.
