CLEAN : Tutankhamun mask: damages are reversible

The video discusses two main statements regarding the mask: there is no current danger to it, and the measures taken are reversible. An incident occurred last year when the mask's beard fell apart due to glue used in a 1944 restoration. The type of epoxy resin used is unknown, but it is a common solution when other methods fail. The glue can be reversed, though it requires careful handling.
