Acid washing raw quartz to remove impurites


Natural quartz, in small granular form, is the main ingredient in Quartz slabs. It is very hard and durable, and occurs abundantly around the world. However, getting a very pure white quartz is hard to find, and there are limited sources of high quality pure white quartz, of the grade that is required for quartz countertops. Some quartz manufacturers resort to “acid washing”, a method of enhancing the appearance of quartz is through a process that involves the use of hydrofluoric acid to remove impurities and stains. While acid washing can improve the aesthetics of quartz, it has harmful environmental effects that cannot be ignored.

The primary environmental concern with acid washing quartz is the release of hydrofluoric acid into the environment. Hydrofluoric acid is a highly corrosive and toxic substance that can cause serious harm to living organisms and the environment. The acid can quickly react with other substances and release toxic gases, such as hydrogen fluoride, into the air. These gases can cause respiratory problems and can be fatal in high concentrations.

Moreover, hydrofluoric acid can also leach into the soil and water, which can have devastating effects on local ecosystems. The acid can lower the pH level of the soil, making it difficult for plants to grow and survive. In addition, the acid can react with metals and release toxic chemicals into the water, such as lead and mercury, which can harm aquatic life and contaminate drinking water sources.

Guava Quartz is steadfastly against this process, and uses only the highest quality quartz that does not require acid washing. This of course comes at a higher cost, but we will not compromise either on the quality of our product or our commitment to the environment.
