During the examination some fibrous residue was found in the concretion. This gave the appearance of a type of felt, which might have been used to wrap the item

Clearly orriginaly the shape of the object was bent

From a side profile a series of iron nails can be seen in the concretion

 A cross section of the ghost item which came close to the beaker.

Some of the concretion has been carefully removed from the French faienceware beaker, leaving a "tide mark"

Some concreted nails next to the items, forming large ghosts

The outer shell of the concretion was intact and strong

Further cuts showing the square sides of the original item

Cross section showing two items in the concretion. As further cuts were made the ghost items got closer

Here a depression can be seen above the void

The depression is now clearly an item of its own at a further cut 4 cm away from the last

One can see right through the ghost along the longitudional axis

The underside

The fourth concretion to be examined but not cut, using the other cuts as a basis of the analysis
