I found this rock hiking, I think it was at Ron King Memorial Police Training Center in Colorado. It is strangely smooth and neither me (who studies geology and mineralogy like crazy) nor a geophysicist can tell what it is. So if someone knows that would be great.
Colorado Springs has a history of ceramics in fancy glazed architectural tiles to art pottery from the late 19th century and on. Most famously is Van Briggle and others like the Broadmoor Pottery Co, plus some others I believe that were smaller pottery makers of the arts and craft era of the early 20th century. My guess is that may be a piece connected to those times.
Yeah, see your point! Thats what I thought it could be because its multicolered and I havent seen any multicolred pieces of firebrick Ill do some research
