Acrylic Drops are available in 10 colours. Size is 32mmx12mm and there are approximately 60 per 100 grams. How to dye acrylic beads. Using Dye can be dangerous - ensure that you carefully read the instructions on the bottle. My choice is "RIT" liquid dye. Using an old glass jam jar, fill to about 25% with "RIT liquid dye", carefully put beads to just below the level of the dye...then cover with glass plate, place in Microwave until it starts to boil. Then allow to cool.
