The safety of lava stone: what the science says

Lava stone is a natural, durable and fascinating material that is widely used for cooking, decorating and design. But how safe is it, especially when it comes into contact with food? And what is known about the possible emission of gases such as radon?

In this article we clearly and scientifically answer all common questions.

What is radon and why it is talked about

Radon is a naturally occurring radioactive gas that results from the disintegration of uranium in some rocks. In high concentrations, it can pose a health risk, especially in enclosed and poorly ventilated environments.

For this reason, many building materials are now being specifically tested for radon emanation rates, although the risk is only real with prolonged and continuous exposure.

Etna lava rock and radon: what studies say

Several Italian scientific studies have analyzed radon emission from various natural stones, including:

• Etnean lava basalt
• Other granites, marbles and tuffs

The results show that lava stone from Etna is well within the safety limits set by the European Commission for cladding materials. The measured values are below the threshold of 2 (specific emanation rate unit), which is the exemption limit for materials used in construction and furniture.

In summary: there are no risks associated with the use of natural lava stone for home or food environments.

Is it safe for cooking food?

Yes, lava stone is suitable for food use, especially if it comes from certified suppliers such as Cuorelavico, who select natural lava stone from Etna that has not been chemically treated.

In particular:

• Withstands high temperatures up to 1000°C without releasing harmful substances
• Does not emit odors or fumes during cooking
• It is non-stick and easy to clean
• Contains no lead, cadmium or other heavy metals

It is therefore perfect for cooking pizza, meat, fish and vegetables both in the oven and on the barbecue.

How to choose a safe lava stone?

Here are some practical tips:

• Make sure it is natural and unprocessed
• Verify provenance
• Choose products from transparent and reliable companies like Cuorelavico
• If used for cooking, opt for plates certified for food use

Conclusion

Lava stone is a safe and reliable material, perfect for domestic and culinary use. Scientific studies confirm this: its radon emission rate is minimal and well below limits. In addition, it is a natural, sustainable and durable material, ideal for those seeking uncompromising quality and beauty.
