I work a lot of hardstone and make copies of artifacts. Both N American and European. Some of my favorites are the stone pipes. The Indians made many style of pipes. I really like the monitor style. Named after the civil war gun ships that looked similar. These were mainly made on the east coast from about 1200-1700s, VA especially, and usually made from black steatite. I use the same design except I use hardstone…igneous rocks much harder than steatite. This one is basalt porphyry. A glacial rock brought down from Canada. The pics show the steps to making one.
