    I have seen others have good luck using polymer clay to make
    impressions of intaglios, carving into stone opposite of cameos, but
    I want to avoid 2 stages. I also have not had good luck removing the
    clay from the glass intaglio without warping the images. The best
    impession I have obtained is from Kerr Extrude Wash, but I then would
    need to make another mold to get a positive, and I cringe at doing a
    mold of a mold. I have bought Protoplast as suggested, a 24" x 24"
    sheet, and I have made one attempt, and it's gonna take more attempts
    to be sure that is good stuff. 

    I am still looking for a material to make a great impression of an
    intaglio. This is NOT a casual question. I have used sculpey,
    parafin, injection wax, sealing wax, hot glue, sprue wax and do not
    get consistent or good results. It seems that with a larger intaglio
    in a 1.5 x 1 inch oval there is just too much to go wrong. I still
    hope to get serious with the Protoplast, but I was not pleased with
    the single attempt, as it left the ripples in the flat surface
    because it does not cool instantly. 

    I have talked to customer service at Kerr who did not even read my
    questions well. I had to ask twice if Extrude Wash could be burned
    out, and then when I asked if there was another material to use,
    they said just use injection wax in the extrude wash, but that would
    just get me another negative. I have talked to owners of other
    companies at other times who were more than gracious like what to use
    as a release agent for Castaldo Pink. The anwer was paste wax. I'm
    going to have to give up and get more Castaldo Pink!
