This article explores how hardness affects performance, longevity, and aesthetics of soapstone countertops. If you’re a homeowner considering this beautiful natural material, this guide will help you make an informed choice.
I’ve been working with soapstone for years, and through SoapstoneGuide.com, I’ve helped countless people navigate the subtle but important differences between types of soapstone. What I’ve learned is that there’s no one-size-fits-all answer – just the right fit for your space, your lifestyle, and your priorities. In this article, I’ll share what I’ve seen work in real homes and shops, with honest insights to help you make a confident decision.
What Is Soapstone and Why Is It So Popular?
Soapstone is a type of metamorphic rock composed predominantly of talc, along with other minerals like chlorite, magnesite, and dolomite. Known as steatite, this natural stone has been valued for centuries for its unique feel, durability, and heat-resistant properties. Today, soapstone is used in everything from sculpting to building durable countertops and fireplace surrounds.
At Soapstone Guide, we cover it all – design, maintenance, applications – but at the heart of everything we do is one clear focus: soapstone carving. This stone isn’t just a building material to us – it’s our favorite medium for creative expression. Whether you’re shaping a small figure or choosing a slab for a soapstone counter, understanding the nature of the stone is essential to working with it. That’s why we dig deep into the differences between soft and hard varieties.
One of the reasons soapstone countertops are so popular is their ability to develop a beautiful patina over time. The material is also non-porous, meaning it’s resistant to staining, unlike granite or marble. But not all soapstones are created equal: their composition, particularly the talc content, plays a major role in their performance.
What Does “Hardness of Soapstone” Mean?
The hardness of soapstone refers to how resistant the stone is to scratches, dings, and surface wear. This is measured using the Mohs hardness scale, which ranges from 1 (talc, the softest mineral) to 10 (diamond). Soapstone generally falls between 2.5 and 5 on this scale, depending on its talc content.
A higher talc content means a softer stone that’s easier to carve but more prone to scratches and surface wear. A lower talc content results in a harder variety, often called architectural-grade soapstone, which is better suited for high-use areas like kitchen countertops.
Is Hard Soapstone Always Better for Countertops?
Not necessarily. While harder soapstones are less likely to scratch and are more resistant to wear, softer soapstones can be easier to shape and finish. Both types offer advantages depending on your needs and expectations.
For instance, a soapstone counter in a high-traffic kitchen benefits from the toughness of a low-talc stone. However, if you love the way a soft soapstone feels and are willing to do a little more care and maintenance, you may prefer its tactile warmth and rich character.
What Makes Soapstone Soft or Hard?
The softness or hardness of soapstone depends primarily on the percentage of talc it contains. Some varieties may contain as much as 80% talc, especially those used in sculpting. These are incredibly easy to shape but not suitable for soapstone countertops or other high-wear installations.
Architectural soapstone typically contains less talc and more other minerals like magnesite and chlorite, which increase hardness. Alberene soapstone, for example, is a well-known American variety often used for countertops because of its balanced hardness and workability.
How Do You Know What Type You Have?
Ask your fabricator or supplier about the specific variety and talc content of your soapstone slab. Some slabs may look visually identical but differ drastically in performance.
You can also perform a basic scratch test using a steel utensil or key. Softer soapstone will mark easily, while harder soapstone may resist scratches altogether. However, always do this on a sample or inconspicuous area to avoid permanent marks.
Will Soapstone Scratch or Etch Over Time?
Yes, especially softer soapstones. The surface may develop scratches, small nicks, or even light gouges from pots, pans, or sharp objects. However, these imperfections often blend into the evolving patina, adding to the stone’s lived-in charm.
To protect the surface, you can use a cutting board to protect high-use areas. For deeper scratches, a quick sanding with coarser grit followed by fine-grit sandpaper can usually smooth the surface.
Does Soapstone Require a Lot of Maintenance?
Compared to granite and marble, soapstone is relatively soft but also easier to care for. Because it’s non-porous, you won’t have to worry about sealing it or damage from water. However, maintaining a consistent appearance might require regular applications of mineral oil or wax.
These treatments darken the soapstone surface, enhance the color of the stone, and help hide minor scratches. A fresh coat of mineral oil every few months is usually enough for most homeowners.
What Are the Best Uses for Soft Soapstone?
Soft soapstones are ideal for areas that don’t get a lot of heavy wear, such as fireplace surrounds, bathroom vanities, or accent walls. They’re also excellent for carving and artistic projects where soapstone is carved out of blocks.
Because they are easier to shape, you can get more intricate edge profiles and design flexibility. Just remember that softness means you’ll need to be more attentive with care and maintenance.
Where Should You Use Hard Soapstone?
Hard soapstone is perfect for countertops, tabletops, and other high-contact surfaces. It holds up well under daily use and is incredibly durable without the need for sealing.
It’s also more forgiving when it comes to heat resistance. That’s why soapstone is often used in professional kitchens or as stone countertops around stoves and ovens.
Can You Combine Soft and Hard Soapstones in One Project?
Yes, some designers intentionally use both. For example, a hard soapstone might be used on the countertop, while a softer variety is chosen for wall cladding or custom trim.
Just be sure to match the color of the stone and test how each slab reacts to mineral oil before installation. Differences in patina and texture can make a project look unbalanced if not planned carefully.
Does the Look Differ Between Soft and Hard Soapstone?
Absolutely. Soft soapstones often have a chalkier texture and more prominent veining, while harder stones tend to appear smoother and more uniform. Once treated with oil or wax, soapstone with oil can take on a dramatic, almost wet look, particularly in deeper greens or dark charcoal gray tones.
Over time, both types will develop patina, but softer varieties tend to show aging effects sooner.
Soft vs Hard Soapstone: Which Type to Choose
This table compares soft and hard types of soapstone based on different use cases: from detailed carving to functional interior applications like countertops and sinks. Use it as a quick reference to select the right stone for your specific project needs.

Here’s one piece of advice I always give to clients and fellow carvers—especially those new to working with soapstone: don’t assume that every slab sold as soapstone is suitable for a kitchen or bathroom countertop. I’ve seen too many people pick a beautiful piece that was easy to shape, only to realize later it had a high percentage of talcum, making it far too soft for daily wear.
Soapstone is commonly used for countertops, but only if it meets certain criteria. Unlike marble or granite, which are naturally hard and dense, soapstone is made under very different heat and pressure conditions. That’s why its hardness is given such wide range, and some varieties can contain as much as 80% talc—beautiful for carving, but vulnerable in high-use settings.
In my own workshop, I once built a vanity top carved out of soapstone that turned out to be too soft—it scratched easily, dulled quickly, and needed constant attention. These days, when I use soapstone for a soapstone countertop, I always verify the types of stone I’m working with and get a full mineral breakdown if possible. It’s worth the extra step. For functional surfaces, choose a variety that’s durable and heat-resistant, ideally mined for architectural use. That way, you get a stone that not only feels soft and warm to the touch, but also stands up to real life—just like granite, but with more soul.
So, whether you’re building out a full kitchen or adding character to a fireplace surround, choosing the right slab of soapstone starts with understanding what lies beneath the surface – literally.
