FAQ: SOAPSTONE COUNTERTOPS |
||||||||
|
What Is Soapstone geologically? Soapstone is a metamorphic rock, primarily made of the mineral talc. It is not anything like limestone, marble, granite, slate or sandstone, it's a totally different animal. It's also not the rock "Talc" which is soft, translucent and used primarily for carving. Real Soapstone is technically called "Steatite", and is related to serpentine (green marble). Soapstone is much less porous then granite, and it's chemically inert, unlike marble or limestone. So it won't be affected by acids and alkalis. |

I hear soapstone
is soft and scratches easily There are many varieties of soapstone, ranging in hardness from the very soft kinds used for carving to the very hardest ones we use for countertops. Yes, soapstone countertops will scratch more easily than granite, which can withstand the most extreme abuse any countertop is likely to experience! But soapstone countertops have been a top choice for hundreds of years in hard working kitchens of Europe & New England (ask Martha Stewart!). They aren't 'polished granite' perfect even when they're new, so another material might be preferable where you want countertops with a formal, dressy appearance. Think of soapstone as you would think about fine hardwood furniture - part of the appeal is that it wears gently. The warm, friendly feel of new soapstone countertops is enhanced by the patina that develops from all the tiny scratches they get over time making them a great choice for a casual, family-friendly kitchen. Of course you may want to avoid unnecessary damage to hard-working areas by using a cutting board--or not... However: if you scratch the counter badly, you can always sand the scratch away with a piece of sandpaper. That's in contrast to most other countertop surfaces, where scratches are often permanent. Also, the process of oiling hides most small scratches. If you spill paint on it, you can sand the whole thing off and start again. Soapstone is very forgiving surface for your kitchen. What if I like the look of soapstone, but don't think I can live with the scratches?If the relative softness of soapstone isn't a characteristic you think you'd cherish, you would be wise to consider another countertop material because it what it is. Nothing else looks or feels just like it, but luckily, thanks to high demand, low supply and the somewhat higher cost of soapstone, there are more and more alternatives available all the time. You might want to check out a honed black granite, Cambrian Black from Canada is a favorite of ours. Honed Absolute Black, an anorthocite many people call granite, is non-porous, very hard and an economical choice. Pietra di Cardosa is an Italian schist and another popular alternative that's harder than soapstone, though not quite as hard as granite, but it is porous like granite and will need to be sealed to prevent staining. How do I seal my soapstone counters? You don't.
Soapstone is extremely non-porous, and unlike limestone or marble, it's
chemically inert and won't react to anything it's exposed to. That's why
soapstone has traditionally been used for laboratory work-tops. So using a
stone sealer is a waste of time and money.
You should oil Soapstone using clear Mineral Oil. Mineral Oil
is sold in most drugstores ($3.00/bottle) as a laxative, so its completely
safe for humans. The oil isn't sealing the stone, it's only a cosmetic that makes the whole
countertop uniformly dark by oxidizing the surface. You need to oil the countertop only to keep it
looking the color you like - if you want it uniformly black, oil it
frequently, maybe once a week. If you like your stone a little lighter in color, and
don't care if its darker here or there, then you could oil it once a month.
What about hot pots? Can I put them on the countertop? Absolutely, soapstone is actually used to build fireplaces and wood-stoves because it can handle very high temperatures without cracking, and it stores heat and radiates it over time. It's a GREAT material for fireplaces, with technical advantages over other stone. I wanted to get Soapstone in a different color Not really an
option, because after its oiled, all varieties of soapstone are
dark-gray/black. There are some varieties which are more greenish than
others, but it's not a big difference. When you first oil soapstone, it
looks very green, but that color goes away as the oil dries. So if you
really want green color, you should consider green marble (serpentine) or
green granite. Different varieties of soapstone? Soapstone comes from small quarries located in various places in the world. Quarries in Vermont and other northeastern states exhausted their supplies some years ago and began importing from outside the US to meet the growing demand they helped to create. Today, most of the soapstone slabs in Seattle's showrooms are imported from Brazil, some under exclusive distributorship agreements with those northeastern companies. You may have heard of Mariana (TM) soapstone, popularized by Martha Stewart several years ago. The Mariana quarry is no longer producing soapstone, but we can now get stone with characteristics very similar to Mariana slabs from the Beatrice quarry in the same region in Brazil. The stone is a naturally quiet gray color, with darker spots and patterning, and some light and dark veins that turns dark gray or black when oiled. Other branded varieties available locally include Original Green, with white veins varying in quantity from block to block, and occasionally Ice Flower (TM), with veining similar to Original Green. These are dependably among the harder soapstones. Popular demand and short supply of genuine
soapstone has lead to a variety of stones being sold as 'soapstone' when
they are actually something else. In this category you'll find
stones such as Pietra di Cardosa and Serpentine marbles that are
often described at showrooms as 'Indian' or 'Italian' soapstone. Most
often
these stones make beautiful countertops, but they aren't soapstone, have very different
characteristics from soapstone and some need a penetrating sealer to prevent
stains. It's very important to know what kind of stone you have. |
