Sounds freaky-and can be confusing. Is it porous? I know you just sealed it but maybe give it a test.call the quarry and send them a pic-they may know more about it.Softness may be a clue. Did it turn deep black after enhancing. Is it flat ?Does it have some cleavage?Mood Swings? Sorry just kidding about the mood swings!On Thu, Oct 20, 2011 at 4:57 PM, Baird Standish <bairdstandish@gmail.com> wrote:
It is very strange. I am told it is blue-black slate, and we have worked on a fair amount of it around here (they quarry it nearby) and have not run into this problem. Also, this is the softest I have run into. Maybe it is some sort of soapstone, but I don't thinks so.

Is the slate even porous-It sounds like something moisture could do but it is a countertop.If the linseed oil penetrated,it wouldnt have been easy to remove-blue black slate can be very dense like roofing quality. The color enhancer is acting like a topical and if the white marks are within the stone maybe they belong there.Could it be soapstone? We did a grey/(black after we loaded it up with mineral oil) soapstone that had these white marks within the stone?On Thu, Oct 20, 2011 at 2:51 PM, Fred Hueston <fhueston@gmail.com> wrote:did you check the stone for moisture..It sounds like you could have a moisture problem. If thats the case the spots will continue to come back--

Hi. We recently touched up a blue-black slate counter that the owner had been treating with linseed oil. The linseed oil created a heavy build up, which we removed and then applied a color enhancing impregnating sealer. The result was great. However there were some white rings and spots that were in the stone (within the stone, not on the surface - like stun marks in marble). After a couple of weeks the white spots are coming back and I am going to apply a little more of the impregnating sealer to see if that subdues them. But I am wondering if there is some sort of treatment I can use on these little areas that will be more permanent and will not require constant touch up.
Thanks much.
