I’m installing a Direct Vent Gas fireplace in the opening to a old capped wood fireplace and I need to enlarge the opening. The house was built during 1946 in Toronto, Canada. After removing some fire brick and metal I came across a course of 4 inch black color block that runs along the top of the main opening. The block has a texture of volcanic rock (lots of holes)The block is also not solid it is shaped like open foundation block. There are no visible fibers. Has anyone ever seen this type of block used in 1940s’ fireplace construction. Did any of it contain asbestos??
thx

Greg, could it be that they are simply ash blocks that were darkened by the smoke.
These less expensive blocks were common at the time your house was built. No asbestos if that's the case.

*An example of what we called Cinder block ?
*Calvin, same thing.I'm trying to picture the texture and it's the only logical type I can come up with.Gabe
