The island of Kotlin, or Kettle (Finn., Retusari, or Rat Island) in general outline forms an elongated triangle, 72 m.
A tea kettle was already whistling when they entered, and the maid rushed across the kitchen to grab it.
From the reverberatory furnace or the kettle the refined lead is siphoned off into a storage (market) kettle after it has cooled somewhat, and from this it is siphoned off into moulds placed in a semicircle on the floor.
The inner kettle is made of silver, and between this and the outside vessel, which is a copper jacket, is a small space for holding water.
Hence the bruised seed is, of ter leaving the fiveroller mill, generally warmed at once in a steam-jacketed kettle fitted with a mixing gear, by passing steam into the jacket, and sending at the same time some steam through a rose, fixed inside the kettle, into the mass while it is being agitated.
The same is done with the kettle one-third filled with liquid lead, and so on until the first kettle contains market lead, the last cupelling lead.
To the bottom, upon coaling the charge, are taken out with a skimmer and discharged into the neighbouring kettle (say to the right) until about two-thirds of the original charge has been removed; then the liquid enriched lead is ladled into the kettle on the opposite side.
In the kettle covered with a hood the zinc is oxidized by means of dry steam, and incidentally some lead by the air which cannot be completely excluded.
The kettle is spherical, and is suspended over a fire-place by a broad rim resting on a wall; it is usually of cast iron.
There is a narrow sand-bar running into it, with very deep water on one side, on which I helped boil a kettle of chowder, some six rods from the main shore, about the year 1824, which it has not been possible to do for twenty-five years; and, on the other hand, my friends used to listen with incredulity when I told them, that a few years later I was accustomed to fish from a boat in a secluded cove in the woods, fifteen rods from the only shore they knew, which place was long since converted into a meadow.
