Juparana Persa

Do you think that Juparana Persa is a weak granite. I have chosen it for my counter top and have heard that it is to porous and weak. I that true. Thanking you in advance for your reply.

 

Dear Lynette:

Although I gave up long ago keeping up with all the juparanas coming to market, (quite frankly I don't have the slightest idea of what juparana means – and everybody else I ever spoke to…) I just so happen to know that the Persa is some sort of mixed metamorphic stone from quartz syenite to quartz monzonite. No relation whatsoever to granite, of course, but what else is new?

 

“ have heard that it is to porous and weak. ”

 

And who told you that? Unless it was your fabricator to tell you that, how qualified was that person to make such a statement?

Most likely slabs of that material are resined by the factory, which would make them permanently sealed. So the porosity shouldn't be a major problem. (Do verify that the slab was resined.) As for the alleged weakness, I really don't know. What I do know is that even the most fractured stones will not create any problem if installed correctly, while even the toughest cookies will crack if the installation is not correct.

But all that means absolutely nothing.

I hope you will understand the true spirit of what I'm about to say. It appears to me that like most other inquirers at this stage you seem mostly interested in the type of stone and/or its physical characteristics. It's human nature at work, I reckon! J

How about if I tell you that a certain stone is a good choice and then you get a low-grade slab or a doctored one? Trust me: the human factor is far more important than the stone itself and should be the only true deciding factor!

In an industry that's virtually unregulated, how good and reputable the fabricator who's is going to process the stone you'll end up choosing is far more important than the stone itself. None of the horror stories that get posted in this very site stem from the stone: they all stem from the fabricator. That is why I seldom make final statements about any one particular stone. There may be differences within the same stone (and I'm not talking about looks, here!) from one bundle of slabs and the next. The slabs may have also been either “doctored” (which is bad), or “resined” (which overall is good) by the factory, which would make a big difference. Even more important, what's a good stone in the hands of some “Michelangelo”?! And again: a reputable fabricator will only carry high-grade slabs, not some “special!”

We have available a very comprehensive article on “How to Shop for a Granite Kitchen Countertop” that will give you all the intelligence you need to venture yourself with confidence in the stone industry jungle, and it includes the world renowned “Lemon juice (and oil) test”, which will enable you to determine on your own the suitability of any stone you will consider! It does carry a small price tag, and you can order it by logging on the Educational Literature section at:   http://www.mbstone.com/literature/literature.htm. It's available in pay-per-download format and I consider it a cheap “insurance premium” to pay when there are thousands of $ involved! Not to mention the little and much needed support you'd be giving to the cause, your cause, since every single penny of the cost of the article will be used to support it.
