The hourglass is made of pure wood and heat-resistant tempered glass. The hourglass is designed for use in the sauna and allows you to monitor a fixed time interval - 5, 10 and 15 minutes. It is best to mount the hourglass on the opposite wall from the heater and operate it simply by turning it. Even after prolonged use, the accuracy of the hourglass remains the same because the grains of annealed and sieved sand are the same.
