3 pieces of kiln-fired clay ?? 3 pieces of terracotta clay (junk item)

Thank you for looking.
These were purchased a few years ago (about 2 years) and have been stored.
They are soft and will indent when pressed.

Terracotta clay also indents when pressed, so I believe it can still be used, but please understand that it is being sold as junk.
