Conservation means keeping something in good condition over time. This is important for things made of bone, horn, and antler (like the antlers of a deer). These things are very fragile and can break or decay easily over time.
Restoration means fixing something that is damaged or broken. When bone, horn, or antler objects get damaged, they need to be restored so that they look and work like they did before.
To conserve and restore these objects, people use special techniques and tools. First, they carefully clean the object to get rid of dirt, dust, and other things that can harm it. They also use special tools to fix any cracks or breaks in the object.
Sometimes, they add extra materials to the object to make it stronger or more durable. For example, if a horn cup has a crack, they might use a glue made from animal bones to fix it.
Conservation and restoration are really important for preserving bone, horn, and antler objects for a long time. By doing this, we can make sure that these special things can be enjoyed for many years to come.
