Despite their beauty, our volcanic stone tables with ceramic top are absolutely weatherproof. They can withstand even the strongest winter in Siberia! The volcanic stone is put into the oven twice at about 1000 degrees Celsius, once before it is painted by hand and once afterwards. The table surface becomes so hard that it is absolutely heat and frost resistant. The colour does not fade even in constant strong sunlight. Even acid and salt will not harm the table top. This makes them the ideal garden tables. Irresistibly resistant.
