原始彩陶造型基本形的形成 彩陶器皿的圆形来源于对自然形态的摹拟,考古学已证实新石器时代已经有了葫芦和其它有硬壳的果实,彩陶很可能摹拟葫芦的一部分作为容器,也可能是对其他生物的象形取意（图1）。彩陶作为容器,要求造型在一定范围内取得最大限度的容量,关键在于决定器皿形体的两侧的曲线。用现代人科学的分析方法,同样的材料,制作圆形器比其它形状的器皿容量大;同样体积,制作圆形器比其它形状的器皿节省材料;同样黏上制作的圆形陶器,比起其它形状的陶器,在干燥时不容易开裂;同样的烧成制作,圆形器在窑内比其它形状的器皿不容易变形,即使略有变形,也不容易被人们观察到。从美学角度讲,制作圆形器（横向的同心圆）比其它形状的器皿更容易权衡比例曲直。这在拉
The basic form of the original painted pottery shape The round shape of the pottery vessel originates from the imitation of the natural form. Archeology has confirmed that the Neolithic has already had gourd and other crustacean fruits, and the pottery is likely to mimic part of the gourd as a container, possibly Is the pictorial intention of other creatures (Figure 1). Painted pottery as a container, requiring modeling in a certain range to obtain the maximum capacity, the key lies in determining the shape of the vessel on both sides of the curve. With modern scientific methods of analysis, the same material, the production of circular device larger than the capacity of other shapes of the vessel; the same volume, the production of circular shape than other types of containers to save material; the same sticky production of circular pottery, compared to Other shapes of pottery, not easy to crack in the drying; the same firing made, circular kiln than other shapes of the vessel is not easy to deform, even slightly deformed, it is not easy to be observed. From an aesthetics point of view, it is easier to make a circular shape (horizontal concentric circles) that weighs proportional curvature more easily than other shapes of vessels. This is pulling
