PURE ORIGINAL INGREDIENTSCalcium Sulfate (2 lb) Baking, Water Treatment & Gardening

Great stuff I’m happy with it

It worked like a charm without baking the calcium. It made medium texture tofu. I don't have a press otherwise I could have made it to firm. Here is the recipe I used.1. Soak Soybeans: Soak soybeans the night before.2. Prepare Soybeans: The next day, discard the soaking water. Use 1.5 liters of clean water to grind the soybeans.3. Boil Soybeans: Boil the pulsed soybeans for 20 minutes, then strain the pulp out using a cheesecloth.4. Warm the Soy Milk: Place the strained soy milk back into a pot and warm it up to 120-130°F (49-54°C).5. Prepare Calcium Solution: In a separate container, dissolve 1.5 tsp of calcium in 1/4 cup of room temperature water (around 70-75°F or 21-24°C).6. Add Calcium to Soy Milk: Stir the calcium solution into the warm soy milk and mix once.7. Let Sit: Allow the mixture to sit undisturbed for 20 minutes.8. Strain Again: After 20 minutes, strain the soy milk again and place it into a soy milk form or container.

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 Amazon. 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 processSo 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

Does curdle my homemade soy milk (one extraction, using an old Joyoung soymilk maker) but I have not yet found a formula for silken tofu. I have tried adding the product after the soymilk has cooled to ~80C, steaming the soymilk mixture, and streaming the soymilk into a mixture of calcium carbonate and warm water then letting it rest totally undisturbed, all without success. Have also tried different amounts of calcium carbonate, within 1-4 tsp per liter without success.The soymilk curds do press nicely into old tofu. I strain the curds with a fine, thin dishcloth from IKEA in a bowl (too lazy to get the tofu press), drain the water periodically, and press with another bowl on top.

This product works great as a coagulant for making tofu provided you follow the recipe's instructions. There is no detectable aftertaste. The only drawback is the price. I bought the smallest quantity to test it so naturally the cost per unit is much higher. However, it is worth the cost to have freshly made tofu, which is superior to the store-bought stuff.

3/4 tsp of gypsum with 1 teaspoon of cornstarch diluted in 3 tbsp of water per 2 cups of hot rich soy milk render to a perfect soy pudding!Works amazing.

I mix calcium sulfate into a thick paste, then let dry into pucks to supplement calcium to my aquarium. Great value for money.

Arrived fast, Is clean and dry. So far so good.I will know in a few weeks when the mycelium starts to grow! :)The hardest part of leaving reviews on a product is that it could take a long time for me to know if the product is really good... it looks good. Is it? IDK, as I haven't gotten results yet...
