Acrylic Beads are high in shine to give a glass like appearance. They can be dyed. Available in 10 colours (or mixed). 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.
