Atterbury Milk Glass Basket Weave Pattern, Master Salt, PAT July 21 1874 EAPG

Very rare master salt milk glass basket by Atterbury of Pittsburgh. On the bottom it reads that it was patented inJuly 21, 1874. I placed two eggs in it because it does look like this is the purpose (eggs not included), but with further research, I learned it is a version of Atterbury's Master Salt.
