Deciphering the Colors of Lava Rocks: Red vs. Black

Volcanic Origins: The Natural Coloring of Lava Rocks

Lava rocks, also known as volcanic rocks, are formed by cooling magma after volcanic eruptions. Magma is a molten rock and gas that changes color when it cools. Temperatures, chemical constituents, and levels of oxidation determine these hues. 

What is the colour of lava? 

During its peak, lava is white, yellow, or orange. This brilliance disappears as the lava solidifies and takes on the color of red, grey, or black. 

What is the color of magma? 

Heated oxidation of iron-rich magma yields red or greyish rocks, depending on the composition. 

What colour is lava grey? 

 Lava becomes grey as it cools and oxidizes. This color transformation depends on the cooling rate of the rock and the types of minerals involved. The black varieties originate from lava and solidify fast with minimum access to oxygen. Grey lava rocks are formed when the degree of oxidation during the cooling stage has moderate oxidation values. These processes generate all the varieties of colors prevalent in volcanic rocks.

Red Lava Rocks: Composition and Best Uses

Why are some lava rocks red?

Red lava rocks result from iron oxidation. Iron reacts to become rusty in color when heated or exposed to oxygen. This makes red rocks glowing, hot, and attractive to the eyes. Red lava rocks are typically used in landscaping and can be placed in a garden or yard. They complement walkways, beds, and fire pits to provide a clear distinction and vibrant pop of color. They are also lighter and porous than traditional soil, which enhances water drainage. Red lava rocks are beautiful natural garnishes. They should be used to create contrast in garden designs or to enhance stony works. Due to their characteristics, they are widely used in landscape work.

Black Lava Rocks: Characteristics and Design Applications

Why is some lava rock black? Black lava rocks are primarily a result of a fast rate of coagulation and a restricted amount of oxidation. Their iron content indicates that the metal had limited exposure to oxygen during the solidification process. Black lava stones are comparatively heavier and denser than red ones. They have a more polished look and are found in most modern-day landscape designs. Black lava is best combined with more vibrant vegetation, water elements, or no ornament structures. Black lava rocks are preferred to establish minimal and orderly appearances. They are an ideal medium for mulch, edging, or the focal points for the famous Zen gardens. Their colour is timeless, and they can beautify most outdoor places with a simple and classy look.

Maintenance and Longevity: Caring for Colored Lava Rocks

Lava stones are strong and do not require constant maintenance, as they can be used outdoors and indoors. To ensure that the color of the rocks remains as it is, one should wash them with clean water only to prevent them from becoming soiled. This regular cleaning procedure contributes a whole lot to their looks, so ensure that they continue to enhance your outlook. Lava rocks should not be cleaned with strong chemicals, as this will scratch them or otherwise alter their colour. The rocks should be checked frequently for signs of abrasion or movement in areas with high traffic. Replacing destroyed rocks helps maintain the overall look and makes your design look more solid. For outdoor areas, lava rocks can endure harsh weather conditions such as rain, sleet, snow, and sun. Lava rocks can remain an elegant and useful design element for several decades when properly maintained.
