Tabhair chun fiuchta go réidh agus coinnigh ag pointe fiuchta go dtí nach mbeidh tuaslagadh luaithe le brath níos mó.
Bring gently to the boil and maintain at boiling point until no more ash can be seen to dissolve.
Is é sin le rá, substaint a mbíonn a fiuchphointe deireanach ag gnáthbhrú an atmaisféir breis is 50ºC níos airde ná a fiuchphointe tosaigh.
That is to say a substance whose final boiling point at normal atmospheric pressure is more than 50°C higher than its initial boiling point.
