Lead Time Capsule
This is our original lead time capsules cast in lead, which has been specifically chosen in consultation with metallurgists and conservationists for its resistance to corrosion when buried underground for long periods (some since Roman times), and the contents found to be in remarkable condition.
Lead is an ideal natural material from which to make a time capsule, many studies have shown that its highly resistant to corrosion when buried underground for many years. It has been used for centuries on church roofs. in stain glass windows and underground pipes (some since Roman times). The Romans also made coffins from lead and you read of how their contents were amazingly preserved.

HOW TO SEAL THE LEAD TIME CAPSULE
Option 1: (Welded by Gas torch) Ask your local plumber or college plumbing dept to seal the time capsule, as they will have experience in lead burning. This method uses a gas torch to produce a welded joint known in the plumbing trade as (lead burning) it will give the time capsule a strong joint totally sealed from moisture / oxygen entering.
Option 2: Welded by Tig torch) Ask a local welding company or college welding dept to seal the time capsule, they will have experience in welding. This method uses an electrical powered tig torch to produce a welded joint. It will give the time capsule a strong joint totally sealed from moisture / oxygen entering.
Procedure: Make sure all the contents are in the time capsule and tuck a piece of card between the contents & the inside of the time capsule for extra safety, then put the lid on and turn the capsule upside down. Firm all-round the joint of the lid with a ball pein hammer to close the gap between the lid & the box. Cut some strips of clean lead roof flashing to use as your welding rod (do not use solder) then clean along the joint with a wire brush or file. Using the smallest flame/amps necessary tack weld each corner to secure the position of the lid. Turn the time capsule on it’s side and weld in small 2” runs moving from one side of the casting to the other allowing time for the casting to absorb the heat within itself, if necessary rest a while between welds so there is not too much heat build up.
