White Lead (Quick Process)
On account of its alkaline nature, this pigment acts upon the saponifiable oil in which it is ground, forming lead soaps which accelerate chalking of white lead—the greatest evil attending its use. Solubility in carbonic acid of the atmosphere and decay in the presence of sodium chloride may be active causes of the rapid chalking of this pigment at the seashore. Checking in some climates appears to proceed rapidly on white lead paints, in a deep hexagonal form, leaving a series of rough crests and cracks. This checking is secondary to the chalking which takes place.

Lead Melting Pots
White Lead (Quick Process). By acting on atomized metallic lead, contained within large revolving [wooden cylinders], with dilute acetic acid and carbon dioxide, the [quick-process white lead] is produced. Its value is equal to the [Dutch-process white lead], and it is considered by some as possessing greater spreading value.
