Your alchemist should create calcium carbide which when dropped into water releases acetylene which will burn in the air above the water''s surface. This is the reaction behind the classic carbide lantern which has been used by miners for centuries.

Hydrofluoric Acid - Princeton University

As serum calcium levels are depleted in the blood, a condition known as hypocalcaemia, organ failure begins to occur, heart function becomes erratic and can eventually fail, obviously resulting in death. An additional quirk of hydrofluoric acid is that dermal burns

Pulverized Lime Side Effects | Healthfully

Heating limestone produces a chemical substance used in agriculture called pulverized lime, or calcium oxide. Generally, 2 mg of calcium oxide is considered safe for food use; however, concentrations of 25 mg can produce serious side effects including lung inflammation, according to a 2007 report by the Occupational Safety and Health Administration, or OSHA 1 2 .
