Hello, Members of the List. EIS can be separated into dissolved ions and particulates by the freezing method disclosed by Frank Key, though the particulates come out of suspension and the separation may therefore not be reversible. EIS can be separated reversibly into suspended particulates and dissolved ions by membrane dialysis. Graham, founder of colloidal chemistry, did this first with membranes made from ox bladders, then switched to vegetable parchment. Vegetable parchment is much more economical. It is still used today for culinary purposes. It allows foods to be cooked by boiling or steaming without loss of valuable nutrients and flavors. Culinary vegetable parchment is called Patapar paper, possibly because it conformed to Hindu vegetarian principles of cooking. Kosher patapar paper is available. Edgar Cayce recommended it use for retaining nutritional value in cooking. Patapar paper sheets are reusable. One typical vendor charges about five dollars for six sheets, each measuring 24 inches by 24 inches.
Does anybody have any experience with this interesting material? Best regards, Matthew
