Moon Dust 1219 Quantra Quartz
Description Moon Dust Quantra is a beige countertop material that is made from highly durable quartz. It can be used for a variety of applications, such as kitchen countertops or bathroom vanity tops because of its strong, stain resistant composition. Because the surfaces are non-porous, sealing is not required for quartz countertops.

Quartz and respirable dust in the Dutch construction industry: a
Concrete drillers and tuck pointers had the highest exposures for quartz and respirable dust (0.20 and 3.43mg m(-3), respectively). Significant predictors of elevated quartz exposure were abrasive tasks and type of material worked on. Surprisingly, in a univariate model, an increased knowledge level was associated with an increase in exposure.

Does Quartz Attract Dust? (Causes How To Clean It)
Dust on the surface of quartz countertops is not something that you have to worry about. The surface has low levels of adhesion, which means that dust particles will be unable to stick onto it in the first place. Additionally, water and oil stains can also cause things like this to happen as well because they increase its level of adhesion greatly.

Quartz
Quartz was the mineral upon which the Stone Ages were based. With few exceptions, most early stone tools were fashioned of quartz. Outcrops of quartz that were suitable for tool manufacturing were targeted by some of the earliest known mining activities and the mined quartz was traded across vast distances, even before humans began to establish agricultural societies.

Does Quartz Attract Dust? (Causes How To Clean It)
Most dust particles are positively charged while quartz is negatively charged. When exposed to each other, they create an electrostatic bond that is strong enough to keep the dust from settling on your countertops. However, there are some instances where dust can settle on quartz countertops. 1. Quartz Is Negatively Charged
