| Description | One box of plastic and metal moulds used by Clive Lee to test polymethyl methacrylate bone cement [likely for "creep" testing]. The original box was labelled 'PTFE moulds for ISO PMMA tests'. The white moulds are made of teflon. [The metal moulds likely produced the cement samples in Box 17/13 and the large metal cylinder and screw in small cylinder were likely used to pop the cement cores out]. |
