The Stone Formula (or Miracle Fluid) is a liquid cure for the Petrification phenomenon developed by Senku Ishigami.

Description

Senku believes the nitric acid in the bat guano helped free both himself and Taiju Oki from the petrification. They refer to the aforementioned acid as a miracle fluid from the cave they were awakened in. By combining that with alcohol distilled from wine, Senku developed his own nital etch (an industrial etching agent).

Senku and Taiju ran endless tests for over a year to find the correct formula for the cure. They tested it on petrified birds and their feathers until one day they were able to free a bird. Senku also tested it on a corpse to prove that broken, petrified humans couldn't be restored. The formula proved effective on humans when Senku and Taiju were forced to use it on Tsukasa.

The completed revival fluid is a compound of nitric acid and alcohol created by filtering miracle fluid from the cave and mixing it with as close to 96% distilled alcohol as possible. The ratio is 30% miracle fluid to 70% alcohol and the reaction won't occur unless it's perfect.

Trivia

• Senku insisted not to tell Tsukasa about the presence and ingredients of the Stone Formula. However, he is later forced to do so when Yuzuriha is threatened by Tsukasa.
• After acquiring platinum, Senku became able to produce a limitless amount of the Stone Formula, with platinum being a crucial component in a device that can produce nitric acid, a crucial ingredient of the formula.
