A bio ethanol fireplace or bio ethanol burner with patented ceramic stone from Xaralyn is the safest method of open fire. The big difference with other similar bio ethanol fireplaces or burners is that the ceramic stone in the Xaralyn burner absorbs the liquid slowly. As a result, not the pure liquid, but the released harmless gas is gradually burned. The result is a safe, clean and easy to ignite decorative fireplace with a beautiful constant flame image.
