Pre-treatment Lantern Base3D Model
This is a copper alloy lantern ring with an oil reserve that make up the base of an oil lantern. This is one of many lanterns, some fragmented and some complete, recovered from the wreck site in 2001-2002. The lead shot inside was used to weigh the lantern down so it would remain stationary even in heavy seas. It is missing its base, so you can see into the bottom of the oil reserve. There would have been a copper alloy component and glass globe on top of this to make up the rest of the object.
It has been partially treated, but the rest of the concretion needs to be removed to make it stable and the internal component pieces need to be cleaned. This may be tricky becuase of it is made of mutiple materials, including copper alloy, lead and leather.
