Can you reuse casting molds?

This might be a silly question but can you reuse casting molds for lost wax casting? I always see people mixing investment for a mold and then using a vacuum machine every time they make a piece of jewelry but I never see anyone reusing the molds. If molds made from investment aren’t reusable, is there a way to use a different material to make them reusable? I also do ceramics and am wondering if that would be an option if investment molds aren’t made to last.
