as that it may not be ignited ; for then the colours are burnt; nor 
in too little a degree; for tho' it receives the colours, yet they 
are lefs fixt; and even cold marble will imbibe fome colours; 
as faffron ftone blue for a fky-colour ; but thefe are foon diffi- 
pated by the leaft degree of heat; therefore, let the degree of 
heat be fuch as fuffices gently to boil the liquor poured upon 
the marble.
