how can I tell if something is soapstone?
Here I am in the thick of kitchen renovations, an I've come to be on very familiar terms with my basement sinks. We've lived here since 1994 and I've never given so much as a passing glance at these sinks other than to make sure the washing machine is draining properly. They're circa 1952ish. They're very large, very dirty, very hard rock like, and very black (if i look under 50+ years of splattered paint) Someone painted the outsides a lovely green color. The same sinks are at my mom's house and my grandmother's house, all same neighborhood, all roughly the same age (though in better condition, so I know that they are a greyish color) so I'm assuming all the same materials were used in that period.
but as I was standing there washing dishes tonight I wondered what exactly are my big double sinks made out of. Could they possible be soapstone? And how could I tell for sure?
