Hi, I’ve recently picked up some nice stones at some of the beaches here in California and thought I would make a sandstone mortar using the grinding and pecking method. Takes a lot of time and patience, but it is a really fun project. The Native Americans often used these to grind acorns, nuts and also paint pigments. I will be posting the finished mortar in a few weeks I hope.
