When investing in countertops it is important to be informed of the different materials. Granite has been popular for a long time in the 2000s but is starting to become less popular yet classics. Both granite and marble are similar in ways but there are key differences between them.
First off, both granite and marble are an all natural stone and porous. Porous meaning that air, water, and other fluids are able to flow through. Both materials would need to be sealed to protect the base layer of the material from scratches and stains.
Each material is made from something different. Granite starts out as an igneous rock that is composed of feldspar, quartz and other materials. On the other hand, marble starts out as a metamorphic and transformed by sedimentary stone.
Since granite consists of feldspar and quartz that are hard materials making granite more durable. Marble is less durable than granite since it has Calcium Carbonate which is softer than quartz and feldspar. Granite will be more resistant to chips and scratches than marble but both are considered heat resistant.
Granite and marble have similar natural color variations but there is a way to tell the difference between the two. Something that helps is granite has grains and specks that might contain different hues like blue, orange, etc. While marble will have a larger “pattern” in sense. Marble will have colorful veins that swirl through the stone with consistent coloring.
