Hello Landseer, Brad Bourgoyne, fritchie, terracotta. Thanks a lot for generously taking time to offer advice on how to best repair my broken sculpture. Elmers seems to be the way to go, and my guess is it is innocuous enough not to compromise the curing of a brush on mold material from Polygel or Smooth-On. I'll keep you posted on results. Many thanks, Tlouis.
