Alabaster is a mineral and a soft rock used for carvings and as a source of plaster powder. Archaeologists, geologists, and the stone industry have different definitions and usages for the word alabaster. In archaeology, the term alabaster is a category of objects and artefacts made from the varieties of two different minerals: (i) the fine-grained, massive type of gypsum, and (ii) the fine-grained, banded type of calcite.

Canopic jars are containers that were used by the ancient Egyptians during the mummification process, to store and preserve the viscera of their owner for the afterlife. The earliest and most common versions were made from stone, but later styles were carved from wood. The ritual use of the jars dates back as far as the Old Kingdom and stayed in practice until the Late Period or the Ptolemaic Period, by which time the viscera were simply wrapped and placed with the body. Canopic jars of the Old Kingdom were rarely inscribed and had a plain lid, but by the Middle Kingdom inscriptions became more usual, and the lids were often in the form of human heads. By the Nineteenth Dynasty each of the four lids depicted one of the four sons of Horus, actings as guardians for the respective organ in their jar.
