Onpouring stones for sauna are an essential component of traditional Finnish saunas. These stones are carefully selected and heat-resistant, and they are placed on top of the sauna stove to create a warm and humid atmosphere. The stones are heated up to a high temperature, which allows for water to be poured over them to create steam. This steam helps to purify the air and promote relaxation. Onpouring stones for sauna are a great addition to any sauna and can provide a truly authentic sauna experience.

Frequently Asked Questions (FAQs)

1. What stones are best for a sauna?

The best stones for saunas are igneous, heavy and rough surfaced stones. Peridotite, olivine (which also has a soothing green colour) and vulcanite are all good choices for this, but granite and other igneous rocks can be used as well.

2. Do you need special rocks for a sauna?

Sauna rocks should instead be igneous rocks, which generally tend to be dense and non-porous. There are some exceptions for igneous rocks that don't make good sauna rocks, but that's because they don't have these typical characteristics. For example, obsidian is too smooth while pumice is too light.

3. How often do you replace sauna rocks?

You should re-stack your sauna stones every year. The stones' structure will change over time in high heat and the pile of stones will flatten. For nice steam, you'll want air to circulate between the stones!

4. Can you use Quartz in a sauna?

Surprisingly, the most ideal sauna rocks are that have been exposed to almost no weather. Quartz and iron rocks or sauna rocks with high quartz or iron content may produce little steam. Some rocks may produce poisonous or bad smells, which should obviously be avoided.
