Hey Oleg, great website... we don't have flouridated water here... if they ever put in we will have to move on... my daughter was raised mainly on non-flouridated water...long thick strong bones, never a cavity yet in her life.. she has always been a full head taller than her classmates and she is the only, the only kid, out of hundreds, in her school with grades to make the gifted program.

But, the recipe with eggshells and vinegar, I have heard of that before but wasn't sure how to do it.. so thanks! But also, my tomatoes will love that! tomatoes love calcium and they love a tad of vinegar in the water to keep the soil a bit acidic and then hopefully they won'tbe munching on pesticide residues that might be in the soil and we get a bigger better crop!!

I'll start tomorrow !

I dropped alum from the pickle recipe a few years ago, calcium keeps 'em just as crisp btw. alum is an aluminum deriviative far as i know. I'll try a batch with an eggshell!!
