A Mortar and Pestle is a very precious tool used for crushing and grounding food, herbs, seeds and other varieties of herbal and mystical medicines. It is recommended to not use the same mortar and pestle for edible and non edible mixtures. Each set is made from soapstone that has been hand carved, painted and polished. The ancient practice of soapstone carving dates back more than 3000 years. Soapstone or steatite is a natural material. The interior of the mortar has a natural finish. SYMBOL: The Celtic Triquetra is the symbol of the Holy Trinity (Father, son, Holy spirit).
