For distilling I draw off tap water [which is poor here] in pails and let sit for 12 to 24 hrs to let the volatiles bleed off,Even then for good EIS/CS, I double distill. As for cooking utensils, I have been doing very little cooking for a long time now as cooked food is dead food,.True , some foods are better cooked lightly than raw,ie, steaming.. I use stainless steel and corning ware,or pyrex [old timers],if I do cook. My diet now is mostly raw fruits and veggies along with juicing with an Omega slow speed juicer. Very happy with the results.
