Pennsylvania Bluestone is widely used for interior and exterior purposes in many parts of North America as well Japan and several other developing countries. Bluestone is colorful, it’s durable in many climates and has a natural non-skid quality making it a sought after stone for commercial and residential projects.
Pennsylvania Bluestone, also known as PA Bluestone, is a sandstone that is prevalent in northeastern Pennsylvania as well as lower New York State. This Bluestone area is relatively small, encompassing several counties in each state.
While bluestone is the general category, there are several different types of bluestone that are quarried with, typically, any one quarry able to provide only one type of bluestone.
One of the most popular uses of bluestone is for outdoor patios. This bluestone flagstone is quarried, cut and separated in layers at the quarry; this type of bluestone flagstone is called “Natural Cleft.” One of the main characteristics of Natural cleft flagstone is its varied surface that may range +/ – ¼”. At Meshoppen Stone, we group like-thickness flagstone pieces together to make purchasing and installation easier for the customer. Our thickness categories are ½”, 1”, 1 ½” and 2 to 2 ½” with normal pattern sizing for patios from 12” x 12” up to 24” x 36”. Larger sizes are also available on a regular basis.
This natural cleft bluestone flagstone is available in blue, lilac and full color. Full color bluestone may range from browns and reds to green-grays and will offer the most color in bluestone patio stone.
Another type of Pennsylvania Bluestone is quarried in chunks that weigh up to 30-tons and are also available in blue, lilac or full color as was the natural cleft. This type of bluestone has only become possible in the last few decades due to being able to harvest this material from the quarries and fabricate it into specific sizes known as treads or slabs. These slabs of bluestone may also be cut into radial designs or intricate logos, such as the New York Yankee “NY” logo using a water jet, which Meshoppen Stone accomplished for the new Yankee Stadium in 2009.
Once the fabrication is complete, the surface is torched to give a unified, natural look to the stone.
The difference between the ‘natural cleft’ and ‘thermal’ bluestone is that the natural cleft has “reeds” or layers, which becomes the thickness of the flagstone and the fabricated bluestone, in essence, is one large layer without any reeds throughout the chunk. Because these chunks are solid rock (without reeds) and have very little grain they can be cut into different shapes and sizes in either direction without jeopardizing the rock, itself.
Bluestone is also specified by architects for commercial and residential interior work. In this scenario bluestone is made into counter tops, window sills, stair treads and floor and wall tile, which may be cut down to a thickness of 1/2 inch. Some other interior uses of this versatile stone are fireplace mantles, hearths and accent areas of the home. Once again, all of this bluestone chunk material is available in full color, lilac and, of course, blue, which is the most prevalent.
The finish on interior bluestone is typically “honed” or “sanded.” The edge work choices available are eased, half-bull nose or full-bull nose. And once the stone is honed, the delicate beauty is brought out and should be retained by giving the stone a “natural stone” seal coat, which will preserve the color of the stone and keep it from staining.
As you can see, Pennsylvania Bluestone is versatile through its many uses and with its elegant, rich color offerings (ranging from lilac to full color and blue) it is complementary when used with natural wood, stainless steel or color finishes, which is why it has been one of the most popular stones to be used in construction and renovation projects over the last 75 years.
Flagstone is a hard quartzite sandstone material specific to Northeastern Pennsylvania and the Southern Tier of New York. Flagstone’s wet or dry non-slip surface makes it a very desirable product for use inside or out.
Flagstone is unaffected by any kind of weather conditions. It is a beautiful stone with many color variations including a mix of soft greens, blue grays, rust, light and dark browns, soft lilacs and select blues which is a range of all the blue tones.
Flagstone applications such as paving, patios, decks, flooring (interior & exterior), treads, risers, hearths, mantels, countertops, window sills, curbing, stepping stones, pool coping, wall caps, wall cladding and column caps.
Flagstone is a very economical product to use in comparison to brick, concrete pavers or lumber so that in these tough times you can continue to increase the beauty and value of your home.
Flagstone is a natural choice for commercial, residential, state and federal projects.
Flagstone is available in several different finishes. Natural cleft is a natural split product that has plus or minus 1/8” clefting on the face of the stone. Thermal finish is sawn on six sides and then thermal treated giving it a textured face. We can also produce a honed or polished glossy finish which is used on indoor tiles, countertops or window sills.
