Dental stone cast needs 24 to 48 hours to evaporate excess water and acquire enough strength for manipulation. The microwave oven is used to save time by drying and disinfecting stone casts. The aim of the present study is to evaluate the effect of microwave oven drying on the compressive strength of Type III and Type IV dental stone in three time intervals-3 hours, 5 hours and 24 hours after pouring. The study involved samples: 60 samples for each type of dental stone. Thirty samples were subjected to air drying at 3, 5 and 24 hours and 30 samples were dried in the microwave oven at MHZ W for seconds at 3, 5 and 24 hours. Microwave oven drying increased the compressive strength of Type III dental stone at the 3 hour time interval from pouring, while microwave drying at the 5 hour interval had no significant effect; and at 24 hour the compressive strength of the dental stone was reduced. For the Type IV dental stone microwave drying had a detrimental effect on compressive strength at all-time intervals.

Lifting stones are heavy natural stones which people are challenged to lift, proving their strength. Some of the stones are so heavy that there has been no authenticated lift in modern times, only legend. Recently, lifting stones have been incorporated into the World's Strongest Man competitions, using various cast, found, or established challenge stones such as the Husefell Stone.
