File:Medieval to Post Medieval crucible body fragment(internal and external view). (FindID 117583).jpg

English: The object is a body fragment from a crucible which David Symons (Birmingham Museum and Art Gallery) suggests possibly dates to the 15th to 17th centuries, or Late Medieval to Post Medieval. The object is ceramic and is incomplete.

The material has a light pinkish-red internal face, with a dark pink-red centre and a dark grey outer surface. It is also very hard and brittle which suggests that the object has been heated at a very high temperature, either over or in a fire. The material has frequent sub-angular inclusions of small stones or grit and other calcareous material, possibly flint, which range between 0-2.9 mm in size. The fragment is 69.3mm x 67.8 mm in size, is 18.8mm thick and weighs 92.97g. The internal face of the fragment is quite coarse while the external face is smooth and light yellowy brown in colour. The remains of a dark brown-red substance are evident on the external surface of the fragment where it has overflowed or spilt down the side of the vessel. Closer inspection of the material shows it to have consistency similar to metal slag, and iron ore in particular. The internal face does not have any trace of this material. In cross-section the object is concave.
