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 desired, such as in certain construction or decorative projects.

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 visually appealing texture makes it one of the most popular choices among volcanic rocks in Tengchong, Yunnan. It comes in two main color varieties: "small hole black" and "small hole ash." The "small hole black" variety from Yunnan tends to be darker than similar types from Heilongjiang and Hainan, which has made it especially popular in cities like Chengdu, Chongqing, Jiangsu, Shanghai, Zhejiang, and Tianjin.

Mesoporous lava

This type of volcanic rock has medium-sized pores that resemble a honeycomb pattern. Its unique visual appeal makes it ideal for artistic and decorative purposes, particularly in cultural landscapes or architectural designs where a natural, textured look is desired.

Rough hole volcanic rock

Featuring large, irregularly distributed holes, this volcanic rock is often used in special decorative applications where a more rugged or rustic appearance is preferred. It can add an eye-catching element to both indoor and outdoor spaces.

Red volcanic stone

Also known as red pumice, this type of volcanic rock forms from the last remnants of magma after a volcanic eruption. It is typically dark red or earthy red in color, and due to its low density, it can even float on water. This lightweight quality makes it highly versatile for various uses. In Tengchong, Yunnan, red volcanic stone has vast reserves and significant development potential. While it was once mainly used for industrial or agricultural purposes, it is now increasingly popular for decorative applications, especially in cultural stone projects. Its natural beauty and unique properties make it a valuable material in both traditional and modern design contexts.
