Have found an Eldorado for a gadget enthusiast. An old man out here in the countryside has passed away and left behind a gigantic stockpile of all sorts of things.
Among other things, there are bricks, some with holes and others without. I'm looking for paving stones and now wonder if the ones without holes can be used as paving stones? I believe that there are different types of bricks and that the regular ones freeze and crack if you lay them in the ground...
Does anyone know how to "identify" different types of bricks?
