Types of volcanic rocks

Millivolcano lava

This type of volcanic rock is characterized by its small, needle-like pores that are evenly distributed throughout the stone. It typically has a grayish appearance and is commonly referred to in the market as "microporous." These stones are often used in applications where fine texture and uniformity are important, making them popular in both decorative and functional settings.

Small hole volcanic stone

Known for its sponge-like structure, this type of volcanic rock features pores ranging in size from sesame seeds to rice grains. Its unique visual appeal makes it one of the most sought-after types in Tengchong, Yunnan. It comes in two main color varieties: "small hole black" and "small hole ash." The "small hole black volcanic rock" from Yunnan is particularly prized for its deep, rich color, which is darker than similar stones produced in other regions like Heilongjiang or Hainan. It has gained significant popularity in cities such as Chengdu, Chongqing, Jiangsu, Shanghai, Zhejiang, and Tianjin due to its aesthetic value and versatility in design.

Mesoporous lava

This type of volcanic rock has medium-sized pores, often resembling a honeycomb pattern. Its natural texture gives it a distinctive artistic quality, making it ideal for use in cultural and architectural decoration. It's especially favored for creating visually striking landscapes and interior designs that highlight the beauty of nature.

Rough hole volcanic rock

Unlike the more refined types, this volcanic stone has large, irregularly shaped holes that are unevenly distributed. Its rugged appearance makes it suitable for special decorative applications, often used in outdoor or industrial settings where a bold, natural look is desired.

Red volcanic stone

Formed from the last remnants of magma after a volcanic eruption, red volcanic stone is typically dark red or earthy red in color. It has a low density and can even float on water, which is why it's also known as "pumice stone." In Tengchong, Yunnan, there are vast reserves of this material, offering great potential for future development. While it was once mainly used for industrial or agricultural purposes, it is now increasingly valued for its decorative qualities, especially in cultural stone applications. Its unique color and texture make it a standout choice for modern design projects.
