* For hot-process soaping, plan your double-boiler size as 1 quart per pound of oil.
* For each pound of oil, expect 1.1 pint of oil and 0.4 pints for water, lye and additives.
* During hot process, expansion can be over 50%. More room means more time to notice. If you hover, then you can get by with less. If it starts to volcano, stop the blender and mix by hand.
* Approximately 17 grams per cubic inch (or 27 CuIn per LB)

* No teflon or aluminum
* Icing bag can come in handy for molding, or just use a spoon.

* [http://amazon.com/dp/B002SQII6W/tag=xaminvario-20 Tube Mailer 3` X 24` Duck 1163120] – $7.88 prime – Cut in half for two 12` molds with locking plastic bottom cap. (Holds 6 pounds)
* [http://amazon.com/dp/B000ZJQF7S/tag=xaminvario-20 Mailing Tubes with Caps, 3` x 12`, White, 25ct] – $34.45 shipped, case of tubes, 12` inside, plus 2 caps each. It doesn’t say, but a case is 25 (confirmed by dimensions).
* Visit your hardware store for 12` sections of 3` PVC pipe. Also, empty salt cans are about 3.05`, which work great. Oatmeal cans are about 4` which is okay for half-moons.
* [http://amazon.com/dp/B006Q5UORM/tag=xaminvario-20 5x20x1.5mil Plastic Bags] – $33.98 shipped for 1000. Use as liners in 3` tube molds (some side wrinkles since circumference is 9.42`) and empty salt cans (snug fit).
* NOTE: You can use a 4` tube, but that’s pretty big. If you cut it in half, then half-moon soaps are pretty. Plastic bag liners will leave more crinkles in the soap, unless you can find 6.3` or 6.5` liners. In a pinch, you can use produce bags, but expect a lot of mess around the edges. I like parchment paper.
* [http://amazon.com/dp/B003VFUY0C/tag=xaminvario-20 Freshware 6-Cavity Silicone Mini Loaf Pan] – $10.77 prime – 6 bars at 4.6` X 2.5` X 1.2`.

* [http://www.amazon.com/gp/product/B000VAVD3M/xaminvario-20 Fox Run Wood Cheese Slicer] – $13.45 prime, and it allows you to make consistent cuts. Beware that QC is low on something this cheap, so make sure you mark a perpendicular centerline with a T-Square, and mark your default cut lengths parallel to the slice wire.
