Getting clay from clay tile

How do you get clay from a clay tile? I don’t see an ‘extract clay’ option in the & menu anywhere and if I dig a pit I just get rocks and soil.

Extracting clay is done through the construction menu, " * ". You need a shovel as well, I believe.

Wow. I seriously hadn’t noticed the * menu existed. Thanks.

not a shovel forcefully, just a tool with digging quality
