[0014] The present invention relates to a method for producing a slab-shaped stone product 1 from natural stone 2 , comprising removing, in thinner slabs 1 , the stresses occurring in said stone 2 . The method implies that the stone 2 is dried so that a stress relief of the stone 2 is obtained. According to the invention, the stones 2 are dried therein from the inside by using a microwave dryer 3 in which the stones 2 remain for a certain period of time so as to obtain their stress relief.
[0015] By housing the stone 2 inside the microwave oven 3 for a certain time, the entire stone 2 is efficiently dried from the inside 4 .
[0016] After drying in said microwave oven 3, the stones 2 are heated to at least 100° C. for a certain time. Preferably, the stone 2 is further heated and dried by using infrared radiation 5 of the stone 2 .
[0017] After said heating of the stone 2, said stone 2 is cooled to room temperature of about 18 to 25°C. Acquiring this cooling varies quic...
