Coinnigh an teocht seo ar feadh tréimhse idir 4 agus 16 huaire an chloig (m.sh. thar oíche) chun an t-ábhar carbónúil a bhaint amach agus ansin oscail an fhoirnéis agus lig di fuarú. (feic Nóta (c))
Maintain this temperature for 4 to 16 hours (e.g. overnight) to remove carbonaceous material and then open the furnace and allow to cool (see Note (c)).
