As i thought the clay master would have to be a clay that remains pliable rather than a clay that gets solid

Wrong - it does not "have" to be pliable. When I purchased the silicon, I had two choices to make the master - plaster or modeling clay. Neither of which are pliable. These two materials are also compatible with silicon, some materials used for masters will not allow the silicon to cure - you will need to check with your supplier if going down this path.

My master would have come out easily if I had have made a 2-piece mold, although wanting to save money on the silicon I opted for the economical 1-piece mold.

When i made my moulds the mould making stuff is really hot and destroys modeling clay, so i thought your silicon moulding material might be the same stuff and that would be the reason you needed a ceramic clay original.

Plaster does get hot, silicon does not.
