I'm planning to create a clay scale mock-up of a project and the most
convenient base I have for it is a scrap chunk of particle board. The clay

significantly degrade the particle board in any way? If so, can I use
plywood or should I stick to solid pine?

How big is the mock up? You can buy a pizza stone.
