Hi Richard,

    Yes, it's glass. The original claim by the manufacturers of the
    material, sold to faceters by the ton, was that it contained ash
    from the eruption. It was available in at least 3 shades of green, I
    still have some here (I lived in WA at the time). Testing has shown
    that it does NOT contain any ash from the mountain, none. 

    I know who was making it and I know their sole agent at the time.
    His remark was "Well, we waved some ash over the melt, does that
    count?". It was trickery, designed to sell a bunch of green glass to
    faceters and to the public, and it worked. It's still happening,
    visit Sea-Tac airport sometime. The vendors will GUARANTEE it is
    made from ash from the eruption. 

    EVERYONE who has used ANY ash from this explosion as a glass melt
    additive has achieved the same result.....an opaque brownish glass.
    All attempts to make a glass or glaze from the ash. whether in a
    reducing, neutral or oxidizing environment yields opaque brown/black
    material. The whole thing is bogus. 

    The more recent material has a small amount of lead added to raise
    the RI, and it is very pretty. But, so is faceted Coca-Cola bottle
    bottoms.
