tractorbeast 27 #1 Posted December 2, 2012 Does anyone know what these might be? I believe they are both ceramic, the black looks like it was glazed and fired in a kiln. These were found in the ground of a dirt floor garage. thanks Share this post Link to post Share on other sites
JimD 3,345 #2 Posted December 2, 2012 (edited) They might be ceramic heat cores for some sort of space heaters, The unit heats them up and they transfer heat to the room. That's my S.W.A.G. :) Edited December 2, 2012 by JimD Share this post Link to post Share on other sites
