Tempered ice refers to ice, often block ice, that has been allowed to warm slightly before being used.
Tempering is a process applied to ice, particularly block ice, where it is allowed to warm up gradually from its freezing temperature. This controlled warming period before use is crucial for several reasons related to the ice's physical properties and appearance.
According to sources, tempering allows your Block Ice to warm up before use. This step is essential to prevent undesirable outcomes when the ice interacts with warmer liquids.
Why Temper Ice?
Tempering serves key purposes in ensuring the quality and usability of ice:
- Prevents Cracking: Ice that is too cold can undergo thermal shock when a warmer liquid is poured over it, causing it to crack. This cracking gives the ice a "flawed appearance". Tempering the ice reduces the severity of the temperature difference, minimizing the risk of cracking.
- Restores Clarity: The tempering process can also address issues like frostiness or freezer burn on the ice surface. These conditions can cause a cloudy appearance. Tempering can help restore clarity to the ice, making it look better.
In essence, tempered ice is ice that has undergone a specific warming process to improve its structural integrity and appearance, making it more suitable for applications where clarity and resistance to cracking are important. It's a technique used to ensure the ice performs as expected without visual defects caused by temperature shock or storage conditions.
