Some Meroitic towns, like Karanog, continued into the X-Group Period. Some X-Group houses were built of
mud-brick, while others showed a distinctive feature of this period: the use of small and irregular sandstone slabs,
plastered with heavy mud mortar. Other houses were built of a combination of brick and stone.
The Nubian industry of pottery-making continued into X-Group times, since archaeologists found an X-Group pottery
kiln at a site called Debeira East. X-Group pottery, however, shows very different shapes and decoration from Meroitic
types. Almost all the X-Group pots imitate Egyptian forms, which, in turn, imitate Roman shapes. Most are undecorated
There is also archaeological evidence for iron-working in the X-Group Period, because many large objects made of this
metal, including knives, swords, frying pans, axes, and hammers, have been found at Lower Nubian sites.
