2VE509-ABR: India All Mixed Up Black/Grey Family Aurora Borealis Finish - 200 Gram Pack
Glass bead mixtures from India often appear to be dusty. This dusty grey material is called 'kiln wash' or 'slip' and is used to help the bead release from the wire upon which it was formed. Simply rinse your beads off in the sink or wipe off with a piece of cloth to remove the slip.
