The "water" refers to placenta; when a pregnant woman's "water breaks", it is harvested and added to the mix, which is rolled out on the lily-white thighs of virgins who have never exposed their thighs to direct sunlight; hence the "white" in the name. Rosin, as you probably know, is a by-product of heating up resins from pine trees. Only the finest and hardiest pines, over 1000 years old, are used to source the resin used to produce the rosin in this solder. Add to that the elaborate ceremonies performed at each stage of production, and the careful timing to ensure that each step occurs at the astrologically optimal time, and at only 2-3 times the price of ordinary solder, it's a real bargain!
