When coming in contact with cool surfaces, thefumes deposit a solid material known as soot, consisting ofthe ore dust, ash, some tarry hydrocarbons, and the products ofthe decomposition of the CO^ into CO and O. The mostimportant condensed constituents are water, sulphates ofiron, alkali mercury, and sulphuric acid. The water absorbsfrom the condensed vapors, sulphurous acid, chloride ofammonia, hydrocarbons, etc. The sulphuric acid, especiallywhen present in large quantities, as in the case when roasting 240 QUICKSILVER RESOURCES OF CALIFORNIA. highl)^ pyritiferous ores, is a most troublesome product, as itattacks every material out of which condensers are soot is an intermediate product, which is only detrimentalwhen it forms in excessive quantities. It has the advantageof retaining the minute globules of mercurj^ which form at themoment of sublimation and
