1. First of all, we can see from the appearance that marble has irregular patterns, and quartz stone has some small sequins on it.
2. We can also distinguish by listening to the sound. Gently tap the two stones, the sound is slightly dull, and the sound is slightly crisp, which is marble.
3. It can be detected by chemical methods. Drop a few drops of dilute hydrochloric acid on the two stones respectively. If there are bubbles, it is marble, and if there are no bubbles, it is quartz. Because dilute hydrochloric acid reacts with marble to produce carbon dioxide, there is no change in quartz stone without reaction.
4. It can also be distinguished from the weight. If two stones of the same size are heavier than marble, the lighter is quartz, because the density of marble is higher than that of quartz.
5. You can also use a knife to gently scratch the two kinds of stones. The one with scratches is marble, and the one without scratches is quartz stone. Because the hardness of quartz stone is relatively high, it is not easy to scratch.
I wish everyone can find stones suitable for their home decoration. Xiamen Smarter Stone welcomes your choice！
