Vessels of glass or glazed earthenware should be used for the reduction, while long swords can be put into tall glass cylinders or into wooden troughs, the interior of which must be coated over with paraffin.
Glass vessels or glass cylinders are most suitable because the process of reduction can be watched, but large objects will of course require glazed earthenware baths.
Theoretically, this should reduce the condensation loss by one-half, and if three cylinders are used, the loss should be only one-third of that in a simple engine.
In the tandem design it is often omitted, the piping between the two cylinders being made to answer the purpose.

Gysser recommends to mould the peat for charring in the form ofcylinders of 3 to 4 feet long, which, when dry, may be built up into a heap like wood.
A great change of method arose when iron cylinders and in some cases brick cylinders or wells were adopted for foundations.

In some cases the piers are cast ironcylinders 10 ft.
The two air cylinders are placed below and in tandem with the steam cylinders as in the last case.
The engines are generally built in pairs, with two blowing cylinders and one high-pressure and one low-pressure steam cylinder, the piston rods terminating in connecting rods which are attached to the pins of the two cranks on the shaft.
This plan is always adopted where the cylinders are placed horizontally, and often in the case of vertical engines.
