The first Modified-Basketmaker pottery was crude and limited in form with many globular shapes somewhat reminiscent of those of gourds or baskets. Perforated side lugs were very characteristic. The dominant ware was a light to medium gray with a coarse granular paste tempered with quartz. This occasionally became black from smoke carbon. Exteriors were often marked with striations, suggesting that the vessels were rubbed with a bunch of grass while still wet. There were some bowls with interior decorations applied with black paint. The paint is believed to have been made by boiling the juice of some plant, such as bee weed, which still provides pigment for Indian potters. Brushes were probably made by chewing the end of a yucca splint until the fibers separated and were soft and flexible. Designs appear to have been taken, to a great extent, from basketry. They usually consist of bands or ribbonlike panels and the most common design elements are dots, small triangles, rakelike appendages, and crude life forms. No kilns were used and pottery was probably fired with a conical pyre of firewood placed around the vessels. When the air is kept out and there is no excess of oxygen in the atmosphere in which pottery is fired, a white or gray colored background, such as is found in Basketmaker wares, results. Such pottery is said to have been fired in a _reducing atmosphere_. When air is allowed to circulate and there is an excess of oxygen in the atmosphere, red, brown, or yellow pottery is produced, and the vessels are characterized as having been fired in an _oxidizing atmosphere_.[15] In a few sites there has been found a highly polished red ware, sometimes plain and occasionally with designs in black, and a pottery with red designs on a brown or buff background.[95] These wares are much better made than those previously described and this, coupled with their rarity, indicates that they were foreign to the Modified-Basketmaker culture. It has been suggested that they may have been imported from the south and that the red pottery, which owes its red color to firing in an oxidizing atmosphere, may be the product of the Mogollon people, of southwestern New Mexico and southeastern Arizona, who will be discussed in a later section. Certain Modified Basketmaker vessels were covered with a wash of red pigment which was applied after firing and which was impermanent. This is known as _fugitive red_. The theory has been advanced that this may represent an attempt on the part of the Basketmakers to produce red pottery without knowing the firing technique which was responsible for it.[7] [Illustration: Fig. 18—Modified-Basketmaker figurine and nipple-shaped object.]
