Amerindian ceramic vessel were mostly formed with the coil method, in which strips of wet clay are jointed in circular patterns fused together to make cups, bowls, jars etc. The geometric design of this bowl shows a sequence of points under the rim. This appears most frequently in the Meillac culture, which is the one Columbus met in the northern part of the island. He said that they had their own language and were another ethnic group aside from the Taíno. Archaeology made it possible to confirm differences in culture traits that existed.
