What is powdered calcium carbonate and where can I find it?

Question

It is used as a whitner for cleaning

Answer 1

sorry, only powdered calcium carbonate that I know of is if you crush Tums antacid tablets- most of those are made from calcium carbonate. I know people have used sodium bicarbonate (baking soda) to whiten laundry and soften water. Sometimes lye is used as a laundry whitener- but it is harsh. and... laundry bluing can be used for whitening laundry- don't ask me why it is called bluing when it whitens..I would have to track down that answer too and right now I have my own laundry to get to *LOL*

Answer 2

Powdered calcium carbonate is a long phrase used to disguise an unappetizing "dietary supplement" . It is basically clam and oyster shells ground up in a machine until pulverized and then sold as calcium supllements for people with osteoprosis or people who don't otherwise get enough calcium in their diets.

If you want it as a cleaner, I'd bet there are cheaper and just as effective choices out there. If you must have it, ask at a local vitamin shop if they can order it in powdewr form. Otherwise, ask a biology or chemistry teacher if they can order it from a science catalog.

Or, ask at one of those organic stores that carries the non toxic cleaners and stuff made out of blossoms and pesticide free chickens and such.

Answer 3

Calcium raises pH in acidic soils. One of the best sources is from finely ground oyster shells, which are a by-product of the seafood industry. Oyster shells contain up to 36% calcium plus a natural balance of other nutrients and micronutrients.

You can also obtain calcium from egg shells, but this is only for small gardens or hearty appetites.
