In this video you will learn one of the fundamental steps in the making of quality handmade paper...pulping. Plant fibers are harvested, chopped, cooked in a 3-5% caustic soda (NaOH) solution for about one hour, rinsed thoroughly, and then blended to pulp in a regular tabletop blender. This is a simple process that every handmade paper-maker needs to know and have in their toolbelt when making handmade paper.
Materials:
Stainless steel pot Silicone spatula Sharp Knife or chopper
Cutting board Kitchen Blender Outdoor stove
Colander/Strainer Sheer material Hose with spray nozzle
Bucket/Pail/Tub Rain water (optional) Caustic Soda (Lye/NaOH)
Measuring jug Small scale/balance
How to make a percent (%) solution:
A solution includes both the solvent (in this case rainwater) and the solute (in this case NaOH/caustic soda). To make a 3% solution, weigh out 3g of NaOH; add it to a measuring flask with some water already in it; Add enough water until the solution reaches the 100 mL mark on the flask. A 5% solution requires 5 grams of NaOH made up to 100 mL of solution.
Larger volumes are multiples of these - for example, a 1000 mL solution is 10 x 100 mL = 10 x 3 g = 30 g of NaOH made up to 1000 mL (1.0 L) of solution. Note: NaOH gives off fumes and heat, and can cause burns so conduct this procedure outside with plenty ventilation.
