For most of human history, salt was a rare and valuable commodity that had to be either mined or extracted from the ocean through evaporation. this changed when modern chemistry allowed humans to produce it in factories. how did this development affect the market for salt?

The advancements in the chemistry allowed to produce the salt effectively.

As a result, the salt was easily manufactured in the factories. Earlier, the salt was extracted from oceans, which was a time taking and very difficult process. Due to easiness in the manufacturing of the salt, the availability of the salt was increased. The increase in availability of the salt made by factories, allowed more supply of the salt in the market and the prices of the salts were drop down to a significant level.

explanation:

the fossil record extends back to a dog-like ancestor some 55 million years ago, which gave rise to the first horse-like species 55 to 42 million years ago in the genus eohippus.

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.
