A rockwool is a porous medium composed of microscale pores and macroscale pores. We quantify the capillary rise height and the capillary rise weight in a rockwool. In wicking experiment in rockwool, we show that the early stages and the late stages. In early stage, weight and height scale follow t1/2. In late stage, weight and height scale follow t1/4. The reason why this occurs is that the effect of gravity depends on the height. this study is expected to be used as an important fundamental study for improving the performance by analyzing the hydrodynamic properties of the rockwool.
