## Description

Pure Calcium Sulfate (Gypsum) is Food Grade Powder for Calcium Enrichment, Brewing, Adding Hardness to Soft or Distilled Water, Making Tofu, & More! PURE CALCIUM SULFATE: i. Preservative & Additive Free ii. Contains 23% Calcium iii. Food Grade iv. pH Neutral v. Vegan Applications: Great for baking, brewing, wine-making, pickling, and tofu-making. Can be added to water to increase hardness. Use in the garden to increase calcium and sulfur levels in soil, increase soil's water retention, to treat blossom end rot, or to make mushroom spawn. Use in building to make plasters, molds, and casts. Recommended Use: Food Production: Use according to desired recipe. Water Treatment: Add 1 tsp of calcium sulfate for every 5 gallons of water. Soil Treatment: Sprinkle on soil by hand or using a spreader then water. Use up to 10 lbs. per 1000 sq. feet. Repeat twice yearly. Blossom End Rot Treatment: Mix 4 level tbsp per gallon of water and spray plant with solution. Apply 2 to 3 times per week. Mushroom Spawn: Use according to directions for desired mushroom spawn. Ingredients: Pure Calcium Sulfate (CaSO4) Contains 23% calcium and 19% sulfur.

Review: Gypsum is the dihydrate form of calcium sulfate. Plaster of Paris has 0.5 H2O per CaSO4 molecule. Heat this food safe gypsum in your oven at 300-350 degrees F for 1-2 hours and you can make your own food safe Plaster of Paris! Don’t overheat to higher temperatures (e.g. 400-500 degrees) - this will turn the whole thing into the anhydrous form of calcium sulfate which is insoluble in water and will be useless. I usually mix in some Calcium Carbonate powder to soften the Plaster of Paris - it can be quite hard - depends on how hard your bird or whatever can bite down. A half and half mix of the baked Plaster of Paris and Calcium Carbonate works fine for our double yellow head desertcart. Add water and stir to get a thick batter like consistency, pour into a silicone baking mold (small cupcake size works great) stick a piece of thick natural twine into each cupcake, add nuts and seeds into the mix. The plaster mix sets quickly so you need to have everything ready to stick into the mold with your plaster mix. One time, instead of water, I used grape juice instead - this massively slowed down the setting process. Dunno, it was probably the sugar in the juice, but you might want to experiment with smaller amounts of fruit juice which will probably only slightly slow down the setting process So why do all this? Plaster of Paris from hardware stores is NOT food safe quality and often have acrylic additives to make them stronger plasters for their intended use as a construction material. All these chew toys for birds on the market, especially the ones with calcium blocks - do you know what’s in there? I don’t, and many are made in China. ‘Nuff said
Review: Bag badly damaged (both the paper product bag and the outer plastic bag) and leaked all over the box.
