Found another source for kalk, its not hugely cheaper, but here are the details. Its from a chemical company that my mom orders from to get the chemicals for her lab, there site is http://www.sigma.com and you can order it to your house, you dont have to be part of a lab or anything the cheapest one is $88.20/5kg ($17.64/kg) as apposed to JL @ 24.95 . Not a huge saving....but better then nothing..Although i might be inclined just to get it from JL
