Ash Content of Textile

Apparatus

  • Drying oven – 105° C
  • Weighing Balance
  • Silica Crucible- 40ml
  • Muffle Furnace- 750° C
  • Desiccators

Procedure 

  • Dry the silica Crucible for half an hour at 105° C. cool for about 20 min in Desiccators and weight them (B).
  • Weight 1 gm of sample(A). Keep sample in silica crucible.
  •  Place the silica with sample in muffle furnace at 750° c for 1 h. cool in desiccators and weight them ( C).

Calculation 

Ash content (%) = ( C - B) * 100 / A

       Where

  • A  - Mass of sample
  • B  - Oven dry-mass of silica crucible
  • C  - Oven dry-mass of silica crucible with residue
