Like broken stems from pipes like these;
They were a cheap and major trade item with natives and whites alike. There are some communities in the older parts of town that you can't dig a flower bed with out finding bunches of pipe stems. ( fyi ground up pipe clay was also used to "Blanco" white leather military belts, cross belts, cartridge box straps, any white leather). As you can see they break easily. I broke that one just now photographing these! 😂
