The price of mercury can vary significantly over time, although the price generally ranges from $0.00289 per gram to $0.00869 per gram. Those values are based on a range of between $100 to $300 per flask, with a flask containing 34.5 kilograms.
Deviations in the price of mercury can be seen since production began. In 1980, the price of a flask was $78.29, whereas in 1989 the price was $285 per flask. By 1998, the price had dropped down to $137. In 2006, the price jumped again to $650 for a flask. Price variation is due primarily to fluctuations in the supply.
