Video: Scratch and Acid Testing Granite, Quartzite and Marble

While we do not know the details of the claims made by the consumer made in this video nor do we validate them, we believe that there is a teachable moment here, probably more than a few. What we found of most interest in this video is the relatively simple way that testing can show the difference between marble, quartzite and granite.

This video shows three tests – an etching test, and two different scratch tests, based on the Mohs scale, that can be performed to show the differences in hardness and resistance to acid etching. That is not to say that all three materials cannot be scratched or damaged, just that there are differences.

As to the claims made by author of the video, as to the product misrepresentation, there is no documentation of any kind shown in the video that states he was told he was being sold quartzite, and frankly it is not our intention to address any claims made by either party. Simply the idea is to show the testing processes and the differences in materials.

Overall, an educated fabricator is certainly a better fabricator and is in a position to better educate their customers and set expectations no matter the product they choose. And, expectation setting is key to having happy, well-informed customers.
