I am working on a site outside of Richmond, VA.  I have found what
appears to be industrial waste from a bloomery.  So far I have a
mosser/skull sticking out of a road bank, two pieces of waste iron, and
half of a fire brick with iron adhering to it.  Two questions:


The fire brick (fragment) is marked "MOUN".  Does anyone know of a US
East Coast
manufacturer (mid 19C) that would match?

While it is common for iron to migrate into the wall of a blast furnace,
does the same thing happen in a bloomery?  Or am I seeing waste from two
different sites?

Thanks
