Pulperia was the name given to the company stores of the industries that extracted sodium nitrate from caliche deposits between 1850 and 1930 in Northern Chile in the current regions of Tarapaca and Antofagasta. These nitrate companies were called “ Oficinas Salitreras” or “ Saltpeter villages”, located on the large and arid Pampa del Tamarugal and Atacama Desert, the driest in the world. Due to the extreme conditions of the desert, traveling and providing supplies across the desert was very difficult. Therefore, the companies founded small villages and provided lodging, water and food for their workers. These self-sufficient installations included areas for the extraction and processing of Niter, on-site mining center management, worker’s housing, pulperias, churches, schools, recreation centers, and entertainment.
The pulperías were an establishment that combined the services of the general stores and the Wild West barroom of the United States in the nineteenth century. Instead of using normal currency, the payment system of the wages was through tokens to obtain food rations suitable only in the company store. This system of tokens included fixed prices established by the company to guarantee social and labor benefits to their workers and maintain a certain level of labor stability. However, in the long term, the fixed price system was ineffective in controlling the rising inflation. Moreover, every pulperia had different tokens. More than 2000 different tokens from “ oficinas salitreras” were known, forming one of the more interesting sets of mining numismatic at world-wide level. As a consequence, inconsistency in the token system and failures of the impracticality of the long term price fixed system forced the companies to change the token system to directly paying cash to the workers.
These mining centers were home to thousands of workers and their families from Chile, Bolivia, Peru, and Argentina in the late 19th century and early 20th century. However, the exploitation of the natural resource of nitratine flourished between 1842 (when the usefulness of nitrate was discovered) and 1930 when synthetic nitrate was invented. With the declining sale of nitrate, most of these mining centers were abandoned, causing a massive exodus of workers and leaving lonely ghost towns in the desert.
The pulperia system remained in use by the copper mining industry for a limited time during the 1990s. However, pulperias have since been eradicated in all the mining industries of Chile.
Usage examples of "pulperia".
But if perchance he had to dismount, then, after a while, from the door of that hovel or of that pulperia, with a ferocious scuffle and stifled imprecations, a cargador would fly out head first and hands abroad, to sprawl under the forelegs of the silver-grey mare, who only pricked forward her sharp little ears.
The horseman hammered with the butt of a heavy revolver at the doors of low pulperias, of obscene lean-to sheds sloping against the tumble-down piece of a noble wall, at the wooden sides of dwellings so flimsy that the sound of snores and sleepy mutters within could be heard in the pauses of the thundering clatter of his blows.
