Hello,

    I put the question to the metal clay Yahoo group and Ann Davis
    responded. Here's her answer: 

    "Are you reffering to the Silica Potters sand? It is available from
    all Pottery Supplies. It must be pure sand with no chemicals like
    iron in it...it supports, fills up hollows and highfire- silica
    melts at over 3000' And it's a sand, not an inhalent like
    alumina.....I have been using it for 10 years--the same pile as a
    matter of fact--and I never have collapses or drupes--- I filled my
    puff hearts with it and got...puff hearts" 

Hope this helps,
Linda Kaye-Moses
