hello all and happy holidays....ive had this jug for about 30 years..there are nice drips on the sides and it has what i think is a greenish alkaline glaze...years ago i had another jug and there was an impressed mark on the handle..this jug has an impression on the handle but i cant make out what it says..its about 6 inches tall..thank you for your help andy.....the light spots on the sides are glaze misses or finger prints
