No, it is related to the solubility of calcium hydroxide in water. The solubility of calcium hydroxide in 100g (i.e. 100ml) of water decreases as the temperature increases. The solubility of calcium hydroxide in 0 degree water is 0.185g. , the solubility in 10 degree water is 0.176g, the solubility in 20 degree water is 0.165g, and the solubility in 90 degree water is 0.085g.

Calculated at room temperature of 20°C, the maximum amount of calcium hydroxide dissolved in 600ml of water is 0.165*6=0.990g. At this time, the solution is saturated, and 0.1g of 1g remains undissolved!
