I. Fetal quality: The painted pottery made by the ancient ancestors used high-quality clay that was alluvial by river water. It was pure and free of impurities, and it was like a powder cake; and it was flexible. The pottery made by burning has a "glue" texture with the naked eye.
Due to the poor technical conditions of the firing at that time, the firing temperature was relatively low, and the fired pottery had a strong water absorption. Knocking on the pottery by hand will give a low mute; the weight of the pottery is lighter; the weight should not be heavy; the wet pottery with water can smell a weak smell of earthworms; There are small pinholes.
Ancient pottery, most of which are ancestors' living utensils. Before being buried in the ground, there are traces of bumps on the body. The long-term use of the body has natural wear and tear, and there is a "shell color" caused by contact with air, water, grease and the like. Pulp." The pottery is buried underground for thousands of years, and the long-term accumulation, the surface of the pottery is full of "scale". Real "scale" can not be washed out with water, use the dilute hydrochloric acid brush to test the "scale", you will see "scale" white smoke, foaming.
Second, the shape: the real ancient pottery gives people the feeling: simple, honest, natural, soft, full of vicissitudes, no blunt anger.
In ancient times, there was no standard size concept, and the color pottery made by the system could not appear in the same specification; the same shape and the same pattern. When the ancestors made the pottery, they used the mud-boring method, the mud-plate construction method, the pile-forming method, and the original slow-wheel dressing. The pottery produced was not very regular, with slight deformation and uneven surface. At that time, the level of technology was limited, the interface inside the pottery produced was mostly rough, the bottle mouth was not very round and regular, and the bottle ears on both sides were not on a horizontal line, and the size was different.
Painted pottery of various cultural types has its own unique type category. Collectors should read more books, touch more objects, and memorize the type characteristics.
Third, the painting: painted by the painted pottery is a clan-specific clan symbol at that time. For example, Xi'an Banpo painted pottery mainly paints human face, fish pattern and deformed bird pattern; Majia kiln painted pottery mainly draws swirling pattern, god figure, and network pattern; Xindian painted pottery mainly draws double hook pattern, sun pattern, deer, bird pattern Dawenkou painted pottery mainly painted octagonal and deformed floral patterns.
