Crystal Clear Ice Cube Maker for Cocktail-Circle Shape

Description:
This product is made of BPA-free soft silicone. Makes 8 clear ice cubes of approximately 5.0 cm at a time. Simply fill the silicone ice cube tray with water and freeze for 24-30 hours, with non-stick design, the silicone is durable and easy to remove. 
 
One of the reasons why ice cubes are not completely clear is because of the impurities and gases inside. It is recommended to use distilled water or boiled water at room temperature and pour the water into a filter paper. This reduces impurities. This method is not as good as a professional machine to make a 100% flawless ice cube, but it is close to perfect.
 
Notice:
The cube will crack, If the ice is taken directly from the refrigerator and poured into a liquid.
The ice cubes will clear further when tempered (letting the cube warm up a little). This will also aid in the ice NOT cracking.
 
*Strain through a filter paper before adding water for better !
