Wood I can understand, but why does plaster need covering? Its not
flammable


My immediate reaction to reading that (from a completely uninformed POV)
is that plaster is likely to be formed from plasterboard, which has a
surface layer of paper. Even if skimmed, the heat could make that paper
char.

But another possibility is that, with repeated overheating, plaster will
simply disintegrate. After all, the gypsum is basically made into
plaster by a 'burning' process.
