The quicksilver resources of California . mperature in the furnace, generally to a degree which willdestroy in a relatively short time the refractory material usedin the furnace construction in those parts most exposed to thehigh heat of the flame. From the data given subsequently onfurnace practice, it will be seen what a great difference thereis between the time the ore remains in the furnace in differentreduction works. As in all other metallurgical processes, the end to be obtainedis not perfection from a metallurgical standpoint, but from acommercial standpoint. As in a gold mill it is often goodpractice to neglect the extraction of a small percentage of goldout of the ore, so in furnace practice the amount of ore passingthrough the furnace and the amount of fuel used must begoverned bj^ the condition of obtaining the largest results atthe lowest cost per unit of produced metal. This depends to agreat measure on the special conditions existing in differentplants. It may be here stated that the superintendence of a quick-. PHOTO No. L3. CORONA FURNACE.
