ABSTRACT:
The golf tee comprising a mixture of a clay and a binder wherein the clay is kibushi clay, and the binder includes Na.sub.2 O as principal component, and a resin layer, formed by applying a resin hardened by applying ultraviolet rays thereto, which is weakened by water resin, which is weakened in contact with water such that the resin is formed on the surface of the mixture which is efflorescent. The elasticity of the golf tee increases with the use of kibushi clay and the binder wherein the binder includes Na.sub.2 O as principal component, in comparison with the golf tee formed by only clay. The resin layer increases the strength of the golf tee. The resin layer becomes weak in contact with water. The mixture of the kibushi clay and the binder effloresces. The golf tee is difficult to break, because the elasticity of the golf tee is high, in comparison with the golf tee formed by only clay. The strength of the golf tee is high, so that it can be easily penetrated into a tee ground. Even though the golf tee is left penetrated in the tee ground, the resin layer is weakened in contact with water and thereafter, the mixture of the kibushi clay and the binder effloresces. Therefore, the golf tee does not pollute the atmosphere of a golf course nor is caught in a lawn mower.
