Abstract
In accordance with one aspect of the invention, a mold is provided for receiving a tissue specimen and molten embedding material that improves the ease of withdrawing the embedded tissue specimen. The mold has a barrier coating intimately bonded to one or more surfaces of the mold that repels the attraction of the embedding material to the one or more mold surfaces and produces a positive meniscus of the embedding material in the mold. The barrier coating permits the mold to be re-used without needing to manually re-apply a release agent to the mold before using the mold. Further, the barrier coating permits the use of more aggressive draft angles than conventional molds by reducing the frictional engagement between the embedding material and the mold cavity surfaces.
