It has a low price, is available in every market, is lightweight and can easily be shaped into natural-looking carvings. In fact, lava rock is so easy to carve that after a few dozen pieces, I found I could rough out a small- to medium-size fountain or free-standing stone in less than 15 minutes.
Can you shape lava?
Lava flows can take many shapes and move at very different rates depending on the viscosity of the magma, the slope of the land, and the rate of an eruption. Viscous (or sticky), non-explosive flows produce distinctive landforms known as lava domes.
Is lava rock hard to break?
Unless a strong landscape fabric or layer of plastic is used underneath, volcanic rock can sink below the soil over time. Once below the surface, the rock is incredibly difficult to remove. Volcanic rock is lightweight, which means it can blow, roll or wash away.

After making the wooden outline, attach a tarp on top of it. Then place the tray on a bucket. Now put the large lava rock chunks on the tray. Finally, smash them with the hammer.
Are igneous rocks easy to carve?
Igneous: The characteristics of igneous rocks result from the way in which they were formed. Deep in the earth, under the intense heat of volcanic action, magma was forced up through the older solid rock. It then cooled, forming granite, basalt, and diorite. Graniteis a very hard stone and difficult to carve.

A smaller, very effective tool would be a handheld 4″ or 4.5″ angle grinder (or “cut-off wheel”) with concrete (diamond-coated) blade. These are such versatile tools it’s best to just own one (you can also mount metal-cutting, and different, metal-grinding blades on them – all are super handy).
How long do lava rocks last?
Lava rocks should last for around two years before they start to show signs of wear. Keep using them in your fire pit until you notice them getting a little crumbly looking.
Which is better lava rock or mulch?
Lava rock absorbs heat during the day and releases it during the night. Rock mulches generally slow evaporation from the soil, although if days are warm, dark mulch means higher temperatures, with faster evaporation. If installed with a fabric weed barrier underneath, lava rock creates an effective weed suppressant.
Does lava rock attract termites?
You wouldn’t think that termites would be attracted to rocks. Unfortunately, using rocks outside the house does present the potential for termite infestations. Termites are not after food when they show up under rocks. It is the moisture level that is sustained in the soil beneath the rocks that attracts termites.
