Red-slipped pottery in the Northern Plains reflects the movements of people and ideas around the edges of the Mississippian world. We consider the spread of the technological knowledge necessary to produce red ware, using petrographic data to evaluate local production in Initial Middle Missouri sites. Samples were drawn from Phipps (13CK21; Mill Creek culture, northwest Iowa) and Mitchell (39DV2; Lower James River area, southeastern South Dakota). Granite-tempered, red-slipped ceramics were manufactured in the Initial Middle Missouri region, but were apparently produced at a limited number of sites. The red-slipped pottery at Phipps was not made at Phipps, but could have originated from Big Sioux Mill Creek communities to the west. Neither Little Sioux nor Big Sioux Mill Creek potters made the red-slipped ceramics at Mitchell. Our results suggest the uneven distribution (and perhaps limited number) of potters in the region who could reproduce red-slipped ceramics with local materials. At least some of these potters could have moved from Upper Mississippian communities as marriage partners during other regional exchanges and interactions.

北部腹地的密西西比中部陶瓷：密苏里中部初期遗址的红滑陶器

北部平原的红滑陶器反映了密西西比世界边缘的人们和思想的运动。我们考虑了生产红器所需的技术知识的传播，使用岩相数据来评估初始密苏里州中部地区的本地生产。样本来自 Phipps（13CK21；Mill Creek 文化，爱荷华州西北部）和 Mitchell（39DV2；Lower James River 地区，南达科他州东南部）。花岗岩回火、红滑陶瓷是在密苏里州中部地区生产的，但显然是在数量有限的地点生产的。Phipps 的红滑陶器不是 Phipps 制造的，而是可能起源于西部的 Big Sioux Mill Creek 社区。小苏族和大苏族米尔溪陶工都没有在米切尔制作红滑陶瓷。我们的结果表明，该地区能够用当地材料复制红滑陶瓷的陶艺家分布不均（或许数量有限）。在其他地区的交流和互动中，这些陶艺家中至少有一些本可以作为婚姻伙伴从上密西西比州社区移居。
