Ordinary wear and tear can leave your tabletop looking like a cutting board rather than an antique. One culprit may be the lamp that sits upon it. In order to protect both the tabletop and the bottom of your lamp, apply a layer of felt to the lamp's base. Place the lamp on a piece of felt, and trace its outline with tailor's chalk. Cut out the shape, and apply white glue just inside the edges. Affix to the lamp base, and allow it to dry completely.
Self-adhesive flannel, which comes in sheets or convenient pre-cut dots, is a convenient alternative to felt and is available in most hardware and houseware stores. Use other surface protectors, such as cork or Teflon, on dishes, chairs, and the backs of paintings to keep your home's surfaces looking their best.
