Many of the artifacts featured on this list are centuries old. Yet they remain intact for everyone to marvel at today, and even touch, to a degree. That can make one wonder: how are these objects preserved?
Conservators Laura D’Alessandor and Alison Whyte shared insider details in a 2024 interview with the University of Chicago.

According to Whyte, artifacts go through a rigorous process in which conservators like her determine and maintain the optimal environment for them. Relative humidity and light levels are just two key factors to consider.
“We carry out treatments on objects when necessary, including cleaning, stabilization, repairs, and reconstructions,” Whyte said.

#9 The Silver Coffin Of The Pharaoh Psusennes I (Reign C. 1047-998 Bce)

During the interview, Whyte and D’Alessandro were conserving a collection of nearly 300 glazed clay bricks dating to the eighth century B.C.E. from the Sin Temple at Dur-Sharrukin, in today’s Khorsabad, Iraq.
As D’Alessandro explains, the excavators photographed and labeled each brick before carefully packing them into more than 40 crates.

Whyte then explained that the process of taking them out of the crates required much patience, considering the fragility of the bricks
“Stabilization can involve cleaning to remove any residual dirt from burial, consolidation, and repairs,” she explained. “Consolidation essentially means applying a low concentration of an adhesive to the surface to try to make it stronger.”

A conservator’s job is to preserve these historical relics and make them stand the test of time for future generations to see up close. It is an essential and arduous undertaking, which is why D’Alessandro takes pride in her work.
“We are the caretakers of a remarkable part of the world’s cultural heritage here at the University of Chicago. And it's an amazing resource for people locally, as well as researchers from all over the world.”

#18 A Group Of Ancient Egyptian Glass Rods, Circa 5th-1st Century Bce, Sold At Christie's In 2012

"To create certain designs, Egyptian glassworkers began stretching lumps of glass into long thin rods called canes. These canes could later be re-heated and moulded, and were sometimes used to decorate vessels, or shaped to create earrings."
Millefiori designs, invented in Egypt, fused slices of rods, which were coloured and patterned in layers, like sticks of rock, to form patterns likened to a thousand flowers - millefiori.
It’s amazing how much history can live and survive in a single object. Each artifact on this list offers a sneak peek into a world that existed long before ours. And who knows how many more are still undiscovered?
