    Pat, I don't know if Rio Grande sent me a different product by
    mistake; I'd just *assumed* that it was a bad batch, perhaps from
    too many impurities. But I don't know how silver is refined. Does it
    vary from batch to batch, depending on the quality of the recycled
    material? 

    By the way, the problem silver is very stiff, even after heating to
    annealing temperature. Is a characteristic of anti-firescale silver? 

Janet
