The lead chamber process was an industrial method used to produce sulfuric acid in large quantities. It has been largely supplanted by the contact process.
In 1746 in Birmingham, England, John Roebuck began producing sulfuric acid in lead-lined chambers, which were stronger, less expensive, and could be made much larger than the glass containers which had been used previously. This allowed the effective industrialization of sulfuric acid production and with several refinements, this process remained the standard method of production for almost two centuries. So robust was the process that as late as 1946, the chamber process accounted for 25% of sulfuric acid manufactured.

Famous quotes containing the words lead, chamber and/or process:
“Many of us, whether in the jungles of Asia or on the streets of Chicago, had discovered that noble causes can lead to ignoble actions and that we were capable of sacrificing honor to a sense of efficacy.”

“O birds, your perfect virtues bring,
Your song, your forms, your rhythmic flight,
Your manners for your heart’s delight,
Nestle in hedge, or barn, or roof,
Here weave your chamber weather-proof,
Forgive our harms, and condescend
To man, as to a lubber friend,
And, generous, teach his awkward race
Courage, and probity, and grace!”
—Ralph Waldo Emerson (1803–1882)
“Every modern male has, lying at the bottom of his psyche, a large, primitive being covered with hair down to his feet. Making contact with this Wild Man is the step the Eighties male or the Nineties male has yet to take. That bucketing-out process has yet to begin in our contemporary culture.”
—Robert Bly (b. 1926)
