Nano-Crystallized Glass: What Are Your Thoughts?

Posted on 29 July 2013 by CRadmin2

We recently received an email, here at CountertopResource.com, asking for information on a relatively new surfacing product. This product is commonly referred to as nano-crystallized glass, but it is also known as nano-crystal stone or nonporous marmoglass. After checking the usual sources, we found little readily available information on it, so we decided to do some additional research and see what we could find. Here is what we came up with:

Most nano-crystallized glass is manufactured in China and imported into the United States, but a few American companies feature branded versions, such as Glassos® from CCS Stone Inc. This material is said to be easily cut and tooled with the same techniques and equipment that is used for stone, but some firsthand accounts state it presents a few unique difficulties.

Features of Nano-Crystallized Glass

Nano-cystallized glass is suitable for use as a countertop material, but it can also be used for walls, floors, windowsills, sinks and tabletops.

Much like ordinary glass, it is made of natural materials, and it is chemically inert. Additional features of nano-crystallized glass are as follows:

  • Scratch and stain resistant
  • Heat resistant
  • Hard and durable
  • Nonporous
  • Recyclable

Nano-crystallized glass is much harder than ordinary glass or even standard crystallized glass. On the Mohs scale, it scores from 6.0 to 7.0, and it has a compression strength rating of 400 MPa, a flexural strength rating of 82 MPa and a rupture strength rating of 35 MPa.

Additionally, nano-crystallized glass has a water absorption rate of 0.004 percent to 0.02 percent, and it is totally radiation free. As expected, the material also has a DIN 4102 flammability rating of A1.

Consumers have stated that nano-crystallized glass is a preferred surfacing material because of its nearly pure white color, which is a natural byproduct of its manufacturing process. It is also quickly becoming known as an excellent substitute for white marble.

Fabrication of Nano-Crystallized Glass

Nano-crystallized glass is manufactured from a blend of natural materials that is 75 percent silica and 25 percent other natural minerals. The mixture is poured into a mold to form either a slab or a tile, and it is heated to a temperature ranging from 1,550 degrees Celsius to 1,800 degrees C. for 24 to 26 hours. The high temperatures and the length of time align the molecules of the glass on a nanoscopic scale, which it retains upon cooling and hardening.

Slabs of nano-crystallized glass are commonly available in sizes of 12 ft. by 12 ft., 16 by 16 ft. and 18 by 18 ft. with thicknesses of 3/8 in. or 1/2 in. Tiles are usually made to 24 in. by 24. in. by 3/4 in. Most slabs and tiles are polished by default, but they can be given a CNC satin finish. In addition, the material can be convexly or concavely manufactured for basins and other custom designs.

The cutting of nano-crystallized glass is usually accomplished with continuous blade saws, but it can also be honed, chiseled or sandblasted. The edges can be ground to a bullnose or chamfered. Remnants are 100 percent recyclable.

Installation of nano-crystallized glass is a simple process. The material does not need to be sealed, but a sealer may be added for additional protection. The slab or tiles are most commonly glued to a substrate with a clear resin product, such as Tenax Glaxs BM75, which is engineered specifically for glass and does not discolor from exposure to UV light.

Experiences With Nano-Crystallized Glass

Although the above description makes nano-crystallized glass seem like a wonder-material for countertops, we at CountertopResource.com have heard a few complaints about it being difficult to work with. We have heard that standard CNC tools and continuous blade saws pose some problems, and that hand tools that work well with it are hard to locate.

We know that diamond disc saw blades are manufactured specifically for

cutting nano-crystallized glass slabs, and CCS Stone Inc. offers a full line of tools and supplies for its Glassos brand products, but we wanted to know your take on the subject.

Have you had any experience with working with nano-glass? If so, whatbenefits or complaints do you have about this material? Let us know by email at info@countertopresource.com or simply post a reply to this article right on the website.

    there are some different type of nanoglass because different factory offer the different quality nanoglass according to their technology. we have the super nanoglass(NANO2011),which is very easy to cut like marble. people can test to cut from small sample size 10×10/15×15/20x20cm to know how well it does. for more photo, people can see our website China marmoglass

  2. Anonymous Fabricator Says:

    We have modern WaterJet, CNC technology and equipment in addition to 20 years fabrication experience. Nano glass proved impossible to work with. We had an island countertop about 4′ x 8′ that needed a simple cook top cutout. We did relief cuts to release any internal pressure the slab may have had. We used our WaterJet to cut the cook top cutout and the slab snapped into 4 pieces. On the second try we cored out the corners of the cook top per the suppliers instructions. We installed a new blade especially designed to cut Nano Glass, recalibrated our saw, and refinished our saw table perfectly flat. We started saw cutting at a very slow rate to connect the cored out corners the entire slab broke into 4 pieces at the same places. Then we tried a third time using the WaterJet to connect the cored corners. Same exact breakage. When we cut lamination strips for one of the perimeter countertops some of those shattered too. Perhaps this was a bad batch of material. The supplier said that everyone has problems with Nano Glass slabs. I wish he would have informed us of that ahead of time.

  3. KEN TANG Says:

    Hello, Can you send me your e-mail ?
    We have the real nanoglass, which is nanostone.
    some factory in China use cheap marmoglass or nano2 as nanoglass, however, in our factory, we use the real Nanoglass, which is not break when cutting. after cutting, the edge will be very straight. what is your e-mail? you can e-mail me then we can send you samples to test our materials.

  4. MGK Says:

    CCS has trademarked Glassos Crystal White and Glassos Nanostone, aka Nano White. They have rather different properties. Can you please tell us which one you’re talking about in this article? And I sure wish Anonymous Fabricator would also say which one he used. Perhaps Ken Tang can explain the differences. Are either of CCS’s Glassos products proprietary? I’m also hearing that when it comes to Nanostone, Generation 3 can be worked with the same tools as granite, but not the earlier generations. But is Glassos Nanostone Gen 3?

  5. cradmin Says:

    For clarification purposes, this article refers to nano-crystallized glass generically, not any specific brand. As mentioned in the article, at the time of publishing (July 2013) it was difficult to find information on the product, so the article was based on what was available at the time. That may have changed some now, more than a year later, but we certainly invite any and all manufacturers to submit product releases about the material for inclusion on the website. They can be submitted to info@countertopresource.com, but should be nonpromotional and are subject to editing.

  6. MGK Says:

    The article does reference the brand Glassos, which CCS offers as Crystal White and Nanostone, two different products. Which one does the generic nano-crystallized glass being discussed refer to? And are you saying that Glassos is their trade name for generic nano-crystallized glass or is it their own proprietary version? Here’s a comparison I found on Ken’s site:

    http://www.chinamarmoglass.com/product_d.asp?myiud=885&title=Difference-on-Marmoglass-and-Nanoglass

  7. cradmin Says:

    The article references Glassos as a branded version of nano-crystallized glass. Logic would say it is likely a proprietary version (as most providers probably have their own specific process and ingredient variations for making the material), but you would have to contact the company for specifics. No article is able to cover every variation of a product, and as such, this one speaks in broad terms.

  8. Ken Tang Says:

    http://chinamarmoglass.com/product_d.asp?myiud=881&title=Marmoglass-and-Nanoglass
    this photo show thedifference between Glassos and Nano 3rd generation.
    you can see the samples to identify materials and test to cut the samples to see the inside.
    nano3 will not break, not chip.

  9. David Scott Says:

    I made an order of switchplates from something the customer called “white thassos” and it was fused glass, big surprise on my part! I completed the order fine but I found it difficult to work with and it seemed to dull the tools quite a bit. When I inspected them under a microscope I was astonished to find the diamond crystals were ground down. They all had large flats where there should have been nice sharp points, maybe 30% of the crystal was gone on some of them. I have never seen anything like this in 14 years of doing this line of work. Needless to say it is one of two materials I will not work with, the other is iron ore. It is just too hard on the tools for me to work with it profitably.

  10. CyberBimbo Says:

    There will be another ES that comes out to replace this…eventually. Some will like this and some won’t. It depends which point of view you want to judge this. As a fabricator, restoration & maintenance or retail sales in a showroom. Just like all the ES, Corian, etc. they each have their own sets of issues. All are trends and can fade in popularity over time. True natural stone is timeless but high maintenance. Pick our battles with all this stuff. Eventually some issue will arise and sway consumers away from it but there can be issues with any product. I say enjoy it while it’s popular or moving strong but be prepared to move on to the next trend.

  11. Alex Chan Says:

    There are some different type of nanoglass because different factories offer different quality nanoglass according to their technology. Please find the best nano crystallized stone manufacture. Looking for nano crystallized from a commercial company is taking some risk, because they are not manufacturers and avoiding complain while the trouble come.

    Ps: ‘MillenStone’ is the one brand.

  12. samuel Says:

    Our group just invested the full equipment of producing the Nano ctystallized glass panel.
    This is the advanced line in china Hope can offer you the real nano crystallized glass panel with good price .

  13. Bernie Says:

    The Glassos brand Crystallized Glass is very white and I believe it has superior qualities. I find it much different than other types of crystallized glass. I also find out that CCS Stone in New Jersey also offers Nano White which is quartz based product, not glass, from what I have heard. There is only one generation that never changed. Its the original recipe that everyone is trying to copy, in my opinion.
    CCS Stone fabrication shop in NJ specializes in fabricating this material.

  14. Diana Says:

    I am considering using nanoglass for my kitchen but am concerned about scratches from normal cooking tasks and the cleaning of it in the sense of removing bacteria and sanitizing. I woull apreciate anyone can share their experience on these things.

  15. Tom Heffernan Says:

    Trying to find out how much 1 1/4″ glassos counter top weights per square foot

  16. corban crumb Says:

    We have been trying very unsuccessfully to cut glassos with our CNC/bridge saw. The 3 slabs we tried broke pretty much identically splitting both horizontally and vertically quartering the slabs. We have since got a different blade (alpha silencer III) part No. SLW1610P. Was wondering if anyone had any ideas on what rpm to run it at in order to avoid the blade glassing up. As the manufacture states that the max traverse seed is 25″/min. And also which is better step cutting or just running it through. Logic would point to step cutting but as this is a fairly new product any input would be helpful.

  17. Bryan Says:

    The problem you are having will probably continue for several reasons.
    You are probably cutting on a wood bed and the blade is glazing. Try cutting on cement bed or dress the blade between cuts. Use lots of water. Do not step cut. Go through in one slow pass. Try different blades, different speeds and adjust depths of the blade to achieve minimal chipping. We cut a lot of this type of material. We are the exclusive suppliers of the Branded product called ” GLASSOS” . There are two types of GLASSOS. Our Glassos Nano White is a different than than other so called Nano Glass. Ours is made from White Quartz powder and minerals. It looks very similar until you break it. Nano Glass shears like glass. Our GLASSOS would break like stone. The other type of GLASSSOS is Crystal White. This product is made from Glass Crystals and looks much like Thassos marble.

    Hope this info helps.

  18. Saeed Says:

    Does any one know how to make these material (website or….). I am planning of making it in my factory. I tried to search online but little information on creating this product, raw material, and tools needed. Any help is welcomed. Thanks

  19. Jeff Downing Says:

    We work with the nano glass…waterjet is best way to go.
    It takes about 50% more time than 1.5″ thick PPG Starphire glass to cut.
    Go Slow!
    Polishing requires real skill, and patience.
    BUT, it is well worth it as the material is infinitely better than man-made quartz…it does not yellow (good for outdoors), does not burn with cigarettes (good for bar/restaurant), does not stain (good for everybody) and does not scratch with a knife. I dont know why anyone would use white quartz…especially since they are within 15% of each other in price.

  20. anonymous Says:

    We are cutting an entire high-rise’s worth of kitchens in this material. We found that the nano.dk blade from Terminator is the only thing that works. SLOW cutting but it works 90% of the time – we still have breakage.

  21. Steve Plazza Says:

    We fabricated and install wall panels of the Nano glass.
    some small chips of this glass come off loose.
    how can this be fix,, filled to blend in as less noticeable as possible ?
    Is there a trick or repair kit that anyone is aware?

  22. frank Says:

    As for the cutting,maybe you can replace a cutting blade,if you wanna it,we will show you photos.

  23. Ken Says:

    maybe you can test the AB glue which we use to laminated from 45 degree into 90 degree.
    however, I need see your nanoglass photo firstly, i need know which type or generation of nanoglass you use. you can e-mail your photo to me at xiamentang@hotmail.com
    mostly the nanoglass package with plastic corner to protest the four edge will make it no chip.

  24. Ken Tang Says:

    there are more than one Nanoglass factory in China.
    some people do not compare the sample before they place order,and bought wrong quality for countertops.
    if you want to make countertop, it is better to test the samples from the different supplier and test to cut, see the edge (bottom edge and top edge).

    I have been to a few of the China factories and have spoken with CCS a few times. Currently doing a project with over 100,000 sf of the Chinese version of Glassos…which is ALSO fabricated in China by the way. Very loose specifications and the factory was having a huge failure rate on sink cut-outs. We’re almost there. Beautiful product…hard to work with.

    To Whom, I am fabricating NANO glass from Elaganza stone LA
    Is their anyone that can bring me up to speed on Blades for cutting the beast or fabrication.

    Is there another product in the white glass family that is workable that be recommend to me along with the supplier.

    I have a great amount of work and I need some help.

  29. Ken Tang China Marmoglass Says:

    Hello, Regan.
    we have the right blade for the nanoglass.
    pls email me with the slab photo to xiamentang@hotmail.com
    or info@chinamarmoglass.com
    you can add my whatsapp 0086 13950 111631 to share photo.
    see you soon.

  30. Miguel Says:

    From a fabricator’s perspective, finding the perfect crystallized glass surface is a hit-or-miss. It took us time to find the right supplier who manufactures slabs which are easy to work with.

  31. Regan Says:

    Who is your glass supplier their name and phone number contact information please

  32. Abhilash Says:

    What are the differences between Nano-4 (4th generation Nano Crystallized Glass) and Nano-6 (6th Generation Crystallized Glass)?
    How to distinguish between the two?
    Is there any product called Nano-5 also?

  33. Ken Tang Says:

    From my idea, the market should use Nanoglass 3rd generation.
    because this 3rd generation is stable and matural for many years.
    i do not know why people use nano-4,nano-5, nano-6, which do not improvement on quality and not stable, but just mark a new name. they will similar to Apple, that each year each new product, such as year 2017, call nano7; year 2018, call nano8. i am puzzled.
    so please focus on nanoglass nano3, which is keeping producing and has very good quality, easy to cut, without holes.
    call us for sample test and cutting.

  34. Gregory Scott Says:

    If there are any fabricators in LA who are adept at working with this material, we could use your help. We have a kitchen with Soli Super Thassos countertops, one slab has developed a long crack so it needs to be replaced (we’re trying to get Soli to replace under warranty). On other slabs, some of the mitered edges and seams are rough or have a tiny gap which accumulates gunk, making it highly visible, we’re thinking the wrong glue was used and the right epoxy and polishing would fix that. The work is there if anyone’s interested, we have no confidence in the original fabricator. Contact Gregory – ubk.mix@gmail.com, thanks.
