      Let me begin by telling you a little bit about what I?m
      trying to make. I?m making a head band, it will be a rounded strip across the
      top which dragon-like spikes protruding out of it in two to three rows. Kind of
      looks like shark teeth on a strip. 😛

      The problem is that?s I don?t know what to use for the mold.
      It has to be flexible enough for me to be able to wiggle the original out (which
      is currently made out of a hard wax), and I need to be able to pour the alginate
      or whatever material the mold will be made out of over the original because
      there are fragile parts and odd shapes that a putty wouldn?t be able to fill
      properly.

      I was advised by DeSeres employees that the Gedeo molding
      alginate will be fine to use for the resin and for the time being it was, it captured
      the shape nicely, and I was able to preserve the original when I wiggled it
      out. However when pouring the Gedeo already colored resin to it kind of pushed
      some of the molded alginate apart (but its fine because I secured it together),
      and the main problem was that after about 30h of me waiting for it to dry its
      still sticky and looks like the green (the resin color) is now marbled with the
      white (the molding alginate). The parts that are in the center which had little
      contact with the alginate itself are hard, so I know its not the resins
      problem.

      My question is what can I use to make the mold, that is flexible
      and can handle resin being poured in it. OR what did I do wrong? Maybe I didn?t
      let the mold alginate dry enough before I poured the resin in which caused the
      fusion? When it dried it seems to shrink or like it morphed, is there a perfect
      time where its dry but not yet slightly shriveled?

      Please let me know what im doing wrong, or recommend a
      better product but please keep it in the supplies I can buy at a general art
      store. I don?t have the option to order anything online right now.

      Hi Alice,

      Alginate molds hold moisture and also don’t have a lot of tear strength. They are also only meant to be cast from once.

      I find that don’t work well for what I want to do.
