Perfect for encouraging fruiting of pineapple plants. This is the second year we've used these Calcium Carbide Lumps & the second year we've gotten pineapples. To help induce blooming, all you need to do is drop a few lumps of the CaC2 in a glass of cold or ice water. Allow the CaC2 to dissolve & impart it's acetylene gas into the water.
CALCIUM CARBIDE | CAMEO Chemicals | NOAA
CALCIUM CARBIDE is a reducing agent. May react vigorously with oxidizing materials. The powdered mixture of the acetylide and iron oxide and iron chloride burns violently upon ignition, producing molten iron. Calcium carbide incandesces with chlorine, bromine, or iodine at 245, 350, or 305°C., respectively, [Mellor, 1946, Vol. 5, 862].
