Heat released by curing resin is its exotherm, which is why thick sections are avoided. Ceramic positives are made by slip casting, in which the porous plaster draws water from the liquid clay. A fixed number of casts declared in advance is an edition. Casts made from an artist's moulds after their death are posthumous casts.
The last blank has no settled answer. Posthumous casts are physically identical to authorised ones and were made without the artist's decision, and practice and law differ by country, so it is a real disagreement rather than a question someone has failed to look up.
