White-hot

"The heat of the fire, the steam which arose from the dampening water, the hard slogging at the white-hot metal of the links, and the continual pulling of lengths of chain, were calculated to put a test on the strongest of men, and often on hot summer days they had to be sent home, for the work became unbearable."

"a white-hot rage"

"Flames raced up the rows, blistering and charring and igniting ancient wood that erupted in a white-hot flare of heat."
