Salt and Natural Gas

According to Fang, China has always managed salt and iron, with Sichuan containing many salt deposits together with natural gas, especially in Tzuliuching.[1]:229 "Invisible gas fire" was mentioned as early as the Han dynasty, gas wells were taxed by 1662, gas was used in one tenth of the salt evaporating plants by 1821 (the remainder using wood or charcoal), and by 1857 gas was the more common fuel.[1] Li Jung describes the infrastructure around the salt business, "the building where money is handled is called the cashier's quarters, that immediately above the well is called the pestle quarters, that where the buffaloes turn the wheel to bring up the brine is called the wheel and buffalo quarters, that where the salt is stored in buckets is called the bucket quarters, that where the brine is evaporated is called the oven quarters.[1]:230 The wells used stone casing for the first hundred feet or so followed by wood for another 300 feet.[1]:230 An iron drill weighing up to 267 pounds is attached to a bamboo rope and when brine is reached, the well is called "success" or if no brine is reached by 3000 feet it is called "useless well".[1]:230 A well was drilled to 2700 feet in depth to reach the heaviest brine, the gas rising to the surface with a "rumbling noise", where the gas was contained by a wooden basin placed upside down over the well, from which protruded bamboo or wooden pipes, transporting the gas up to 1000 feet to salt evaporating boilers.[1]:231 Some gas wells serviced up to 700 boilers.[1]:232 Separate pipes carried the brine.[1]:232
