Lead-shot
Important: Safety Warning
This page describes trade processes that use dangerously toxic materials such as cyanide solutions, mercury amalgams, or strong acids. These processes require training, equipment, and precautions far beyond what the text describes.
This information has been left in for historical purposes but should not be acted upon.
The common method of making small lead-shot is as follows: The melted lead is made to fall through the air from a considerable elevation, and thus leaden rain, as it were, is solidified into leaden hail or shot. The tower in which the manufacture takes place is about 180 feet high, 30 feet diameter at the base, and 15 feet at the top. The melting is conducted at the top in brick furnaces built against the wall, the lead is rained down from a colander, through a central opening into a water-tank below. The size of the shot is regulated by the mesh of the colander, the latter being a hollow hemisphere of sheet iron about 10 inches in diameter. When the shot are taken out of the water they are dried upon metal-plates, that are heated by steam, and the imperfect ones are separated from those that are spherical. The addition of a slight proportion of arsenic to the lead used for shot helps it to solidify, as well as rendering it more fluid. The alloy for lead-shot is lead 56, arsenic 1. See LEAD; ARSENIC; HOLLOW-SHOT.

The foliage leaves are the chief organs of assimilation, and develop large quantities of chlorophyll, their form and appearance being very varied. The bracts are generally smaller. The foliage leaves and calyx and corolla leaves become trans- , and these modified formed into stamens into carpels. A leaf is called also a phyllome.

Leaf Gold
See GOLD. Level is an instrument used to discover a line parallel to the horizon, and to continue it at pleasure. Water-level shows this horizontal line by means of a surface of water or other fluid, found on the principle that water always places itself level or horizontally. The common mason's level consists of a long parallel straight-edged ruler, in the middle of which is fitted, at right angles, another broader one, at the top of which is suspended a plummet, which, when it hangs over the middle line of the upright piece, shows that the base or horizontal ruler is level. The spirit-level in common use amongst moulders has brass side-views, brass top, and end-plates and corners, protected by 1/4-inch-square rods extending the entire length of the rosewood staff. The tube, which contains alcohol, is slightly curved, and the straight edge of the instrument is tangent to it. For instructions to level a bed on the foundry floor, see BED.
