This mortar is made from porcelain and the bottom has rubber to make it stay in one place while using it. The pestle has a easy grip on it to handle it better. There is many uses for this set anywheres from crushing pills to grinding herbs and spices. Everyone should has one of these in their kitchen, it comes in handy. The mortar is heavy so be careful with it, it doesn’t land on your finger or toe. These are dishwasher safe for easy cleaning or you could just use soap and water, the bowl itself can be used as a dip bowl. Another must love about this set is that it’s non stick for the pills or food won’t stick to it. I received this product free in exchange for my honest review.
