Nov 21, 2018 · How do you heat Gypsum? Gypsum rock is converted into gypsum plaster by driving off some of the chemically combined water. Heating gypsum at 120°C for one hour results in a hemi-hydrate (CaSO4. 1⁄2H2O) – with three quarters of the water removed. Gypsum hemi-hydrate is also known as Plaster of Paris. What is formula for plaster of Paris?

Gypsum, made up of 21% calcium and 17% sulfate, is one of the best sources of calcium for every plant in your garden. While many gardeners tend to rely on limestone to provide a rich source of calcium, limestone is not water soluble and must come into contact with soil acids before the calcium ions are released to plant roots.

Gypsum isn’t known for its fast-acting results, but after consistently adding it to your soil for three years you should notice that your soil is less compacted and more easily penetrated by plant roots. Over time, this soil will better allow water to run through it. Thus, allowing seeds to emerge from the soil faster.
