clay lover Posted November 10, 2013 Report Share Posted November 10, 2013 I just broke an old mold that I really like. Is there a good way to repair it? It is a clean break. the top half broke cleanly into 2 pieces, right across the center of the form. This is an OLD mold intended for pouring slip into, to made a 3D little animal. I have been putting super soft clay in it and pushing the 2 pieces together, the sloppy clay sqoozes out of the form to the over flow spots, then I open the mold and clean the edges of the piece. I was thinking about making a frame that would hold the 2 halves together. Any suggestions? Will plaster glue old plaster together? Link to comment Share on other sites More sharing options...
phill Posted November 13, 2013 Report Share Posted November 13, 2013 why not cast a new mold? use the old mold to cast a final clay piece and then make a new mold around that piece. Link to comment Share on other sites More sharing options...
Mark C. Posted November 14, 2013 Report Share Posted November 14, 2013 Just remember that every time you cast a piece and make a mold from that piece the item shrinks some ( gets smaller) You can shrink any object down to tiny this way I have used wood glues which are waterproof- tightbond two or tightbond 3 work as well-just be careful about overflow Mark Link to comment Share on other sites More sharing options...
