Ice crystals are used in cryopreservation to preserve biological materials such as cells, tissues, and organs for medical and research purposes. By freezing these materials, ice crystals can help maintain their viability and functionality for extended periods of time. Additionally, ice crystals are used in the production of ice lenses for ground improvement in geotechnical engineering. When water freezes in the soil, it forms ice lenses that can increase the soil's strength and stability, making it suitable for construction and infrastructure projects. **

White ice is not necessarily harder than clear ice. The hardness of ice depends on various factors such as temperature, pressure, and the presence of impurities. Clear ice is formed when water freezes slowly and without any impurities, resulting in a denser and harder ice compared to white ice, which may contain air bubbles and impurities. Therefore, clear ice is often considered to be harder and more dense than white ice. **
