- 4. A golf club head comprising: a face member composed of a vitreous metal material, the face member comprising a face plate for striking a golf ball having an exterior surface and an interior surface, the face plate extending from a heel section of the golf club head to a toe section of the golf club head, a face extension extending laterally rearward from a perimeter of the face plate, and an interior tubing for receiving a shaft, the interior tubing engaging an upper portion of the face extension and a lower portion of the face extension; a crown secured to the upper portion of the face extension at a distance ranging from 0.2 inch to 1.0 inch from the perimeter of the face plate; and a sole plate secured to the lower portion of the face extension at a distance ranging from 0.2 inch to 1.0 inch from the perimeter of the face plate; wherein the face plate has concentric regions of varying thickness with the thickest region in the center, and wherein the golf club head has a volume no greater than 400 cubic centimeters and a coefficient of restitution of ranging from 0.80 to 0.93 under standard USGA conditions.
- 5. A golf club head comprising: a face member composed of a vitreous metal material, the face member comprising a face plate for striking a golf ball having an exterior surface and an interior surface, the face plate extending from a heel section of the golf club head to a toe section of the golf club head, a face extension extending laterally inward from a perimeter of the face plate, and an interior tubing for receiving a shaft, the interior tubing engaging an upper portion of the face extension and a lower portion of the face extension; a crown secured to the upper portion of the face extension at a distance ranging from 0.2 inch to 1.0 inch from the perimeter of the face plate; and a sole plate secured to the lower portion of the face extension at a distance ranging from 0.2 inch to 1.0 inch from the perimeter of the face plate; wherein the lower portion of the face extension has a bore section extending about the interior tubing, the bore section having a width greater than the entirety of the lower portion of the face extension; and wherein the golf club head has a volume no greater than 400 cubic centimeters and a coefficient of restitution of ranging from 0.80 to 0.93 under standard USGA conditions.
