A little qual and quant analyses might be in order here, especially if the precipitate is reproducable. It would help immensely to know just what that white precipitate is if only to eliminate endless speculation. By the way, distilled water may still have solutes in it in small quantities, and glasswear might not be scrupulousely clean. Use 'USP' distilled water instead of ordinary 'distilled' water from the supermarket. A bit more expensive but lends the essential reproducability. YeeGadd, I'm sounding like my old quantitative professor from my days at university. Also clean out the glasswear with an acid-dichromate solution and rinse with some of the USP water. Use gloves and goggles with the acid-dichromate solution. You may or may not be able to get that solution, or even USP water due to the present legal climate around the world unless you are in Africa which is free-er in places....or in Russia.
