(b) Color additive mixtures exempted from certification. A color additive mixture prepared from a previously certified batch of one or more straight colors, with or without any diluent that has been listed in part 73 of this chapter for use in mixtures, shall be exempt from batch certification if the straight color used has not changed in composition in any manner whatsoever since its certification and if it is simply mixed with the approved diluents for exempt mixtures.

Water Soluble.


Dyes may appear drab or even look like the wrong color until it is bloomed.  You must "bloom" the dye before incorporating into your medium for optimal color release.  Don't panic until you have tested a small portion in water.


Take a small amount of dye and add enough water to dissolve the dye powder. Stir or swirl to assist dissolving.  

You can use the dye in liquid form directly into your medium or you can add baking soda to the liquid dye and mix thoroughly until evenly colored.  Sodium bicarbonate (baking soda) is alkaline and can change some colors to an unexpected color.  If this happens, add a half part citric acid to your baking soda part.  This will balance the pH levels and give you an accurate color.  The most accurate test is what the dye looks like in water.
