HINTS:
1. It is not always necessary to add salt, if adding PRO Retayne. Salt and Retayne can be used in combination with each other or individually. A thorough rinse is necessary when using salt.
NOTE: As a rule, use as little PRO Retayne as possible to yield desired results. Begin by adding 1 Tbl (15 gm) per pound (454 gm) of dry pulp.
NOTE: Retention agents (Retayne) can have an adverse effect on light fastness of some of the dyes and is recommended only when necessary.
2. When coloring pulp in a kitchen blender mix in short bursts. Prolonged blending can have adverse effects on absorption of dye.
3. It is necessary to experiment with each color to find the appropriate combinations to successfully dye different types of paper pulp.
