Re: bead problem
Is he sure it's mold?
If he's adding water to the beads by pouring or squiting it on them it could be a few beads shattering into a powder and he's seeing the powder forming a crystaline structure (I've seen this with my beads).
If he's not using distilled or deionized water, then he could be looking at impuritues plating out from the water.
