Red volcanic stone

Red lava, also known as red volcanic rock or slag, is a rock of volcanic origin that forms when lava cools rapidly at the Earth's surface. Its characteristic red color is due to the presence of oxidized minerals, such as iron oxide. Here's a brief description of red lava:

Red lava has a light, porous appearance, resulting from gas bubbles trapped during the rapid cooling process. Its texture makes it ideal for a variety of uses, including horticulture and landscaping.

In horticulture, red lava is mainly used to improve soil structure and characteristics. Because of its porosity, it promotes good soil drainage and aeration. It can be mixed with soil to improve water, air and nutrient retention properties. In addition, red lava can also help regulate soil temperature by absorbing heat during the day and gradually releasing it at night.
