A body is 25 per cent feldspar. If it is changed to 30 per cent feldspar and 20 per cent quartz from 25 per cent each, the firing temperature will most likely
Answer: D
Correct answer: fall, since there is more flux
Feldspar rises from 25 to 30 per cent and quartz falls from 25 to 20, so the change substitutes flux for filler. More liquid forms at a given temperature, so vitrification is reached lower down. The firing range will narrow at the same time, which is the price of the change and the reason the substitution is not made without limit.
