To roll and shape the glass, glassblowers frequently use a large, flat surface known as a marver. While working with glass, several tools are also used. A block is a wetted wooden shaping tool, as is a jack, a bladed tool. To protect the blower from extreme heat, heat shields and paddles are frequently used. The paddles can also be used to smooth out hot glass. Tweezers are another useful tool for grabbing and manipulating hot glass.
