There are many stone vessels from Iron Age sites in Levant. In this paper, stone vessels are clasified into four forms: three-legged form, bowl-shaped form, chalice form, four-legged form. The three-legged form is divided into four types and the bowl-shaped one is divided into seven types.
Stone vessels are divided into two groups. The first group is found before the Iron Age, the second is found only in the Iron Age. The second group consists of four types: three-legged form no. 3 type, bowl-shaped form no. 2D type, bowl-shaped form no. 1A type, and chalice type.
I suggested here that the second group is used for special purpose, because its members have complicated forms and special hundles, and some decorations in comparision with the first group. Many stone vessels of the second group were unearthed after the 9th century B. C.. They appeared before the Assyrian conquest.
