Well Bill the slab that I have was salvaged from a chem lab that had been in use for the last 80 years or so and it still looks great, however to make sure of the flatness I milled it dead flat on a 8' Cincinnati vertical mill. The rest of the counter top including the sink is going into my kitchen.
I do quite a lot of carving in soapstone as there is a lot of it in this area so I do know most of it's qualities. However I was interested in weather anyone else had thought of using it as a Router top material.
(how well will it resists the rigors of being a table top? nicks, dings, impacts, scratching etc..) Well all materials scratch even wood yuh know and as far as repair it's easier than repairing most wooden surfaces and is guaranteed NOT to warp ever as it is one of the most stable stones known.
(How would you make repairs if necessary to the table top?) Although lab counter-top soapstone has a higher silica content than normal soapstone and is therefore quite a bit harder it still machines well so just wet lapping will take out any nicks and dings.
(How resistant is it to liquids? stains? glues? etc...) It's TOTALLY resistant to all liquids including acids and bases although it should be rubbed down with mineral oil from time to time, and as far as glue goes most glues do not stick to soap stone due to it's dense soapy texture, epoxy is the exception.
(How would you secure it?) With machine bolts and epoxied in threaded brass inserts.
How well will it take to fasteners should you decide at some point to "attach" something to your table? Like I said it drills and machines well and is very epoxy friendly so thats not a problem.
So whatYuh think?
