The production cut up used masks into individual rock sections to use as replacements if a section was damaged. I have matched as many cut edges as I can to reassemble sections.
Most are foreheads and cheek areas but also a mouth and unpainted mouth.
There are also small bags and sheets of repair filler sections and notes of paint colour mixes.
Two cap sections that sat on the top of the head and were removeable to allow the actor to cool down.
