These are the same vials of concentrated mirror resilverer's flux sensitizer that ship with our ABC-X Mirror Resilvering Chemical Kits. Each vial of concentrate mixes with distilled water to make 3 quarts of working solution.
Order extras if you mix small batches of resilvering chemistry, or need extra on hand. No shelf life problem, however be aware that once mixed into working solution the sensitizer will last only 4 to 6 hours. Stores indefinitely. Per each. Do not freeze.
