Types of Lava Rocks for Fire Pits

When you look for lava rocks to use in your fire pit, make sure that the type of rock is right. There are various types out there but all can be categorized into three main ones: crushed stone, tumbled stones and natural round riverstones.

  • Crushed Stones – these are small pieces of basalt or other volcanic stone that were crushed into various sizes. These are the most common types of rock and will come in several shapes and colors, but they do not fit well inside a fire pit because you can’t stack them for safety reasons or create patterns when using them on your patio or garden.
  • Tumbled Stones – these rocks have been through a tumbling process which makes them round. They are easy to stack and can create amazing patterns when using for a fire pit, but they do come in different sizes so you have to be careful with the size of your logs or wood pieces since small rocks may not work well with large ones.
  • Natural Round Riverstones – these are naturally rounded stones that can create a beautiful border for your fire pit or an accent in the form of coals and rocks. However, you need to be sure they are not painted because otherwise you will end up with some dirty looking stones.

How to Care for your Lava Rock Fire Pit (Cleaners, Maintenance)?

  • Lava rocks are porous so you will find ash and soot in the rock after burning. If this happens, wash them with water before using again. Use a stiff brush to remove any built up soot or ashes from inside your fire pit bowl.
  • Use a wire brush with high heat resistant bristles to clean the inside of your fire pit.
  • If you want another option, use a mild abrasive cleaner and soak it in water for about 30 minutes before scrubbing away any built up ash or soot from inside the bowl. Use caution while using an abrasive cleaner. Take extra precaution to avoid scratching the bowl.
  • Never use a wire brush or abrasive cleaner on lava rock that is still hot to touch. It can damage the rocks and make them look dull in color over time due to discoloration caused by chemical reactions with cleaners used, heat from fire pits as well as smoke residue from camp fires.
  • For best results, use a mild dishwashing detergent in warm water for scrubbing any built up ash or soot from the bowl after it cools down to room temperature.
  • If you want another option use non abrasive cleaner and soak it in water for about 30 minutes before scrubbing away any built up ash or soot from inside the bowl.

Environmental Protection

Lava rocks are 100% reusable, so you can cut down on the number of stones that would otherwise end up in a landfill. These mineral-rich chunks of hardened magma also help insulate your fire pit area from extreme temperatures and weather conditions outside its borders.

Sourcing these organic materials is sustainable as well since they naturally occur in most volcanic regions of the world.

Safety Tips

  • First, you should always check if the lava rocks are dry and not wet. You can do this by simply attempting to light them on fire. If they ignite easily, then that means they’re still soaking wet with water or other liquid chemicals – which will just cause a lot of smoke when burned and may even extinguish itself.
  • Second, you need to know how much heat resistance your lava rocks have. Different types of Lava Rocks can withstand different levels of high temperatures and must be used accordingly. If the stones are not meant for higher heats then they could burst into flames or crack from excessive exposure to fire. This is why it’s important that you use Lava Rocks that are safe for high temperatures.
  • It’s also important to know how much weight the stones can withstand above ground. If you have children or pets around your fire pit then it may be a good idea to purchase Lava Rocks with less weight resistance. This will cause them not to fall into the fire pit and increase the safety of your living area.
