What is candle ice?

Candle ice is a type of ice that forms in shallow, slow-moving water, such as rivers or lakes. It is named for its appearance, which resembles a collection of vertical columns or cylinders stacked on top of each other, resembling candle wax dripping down the side of a candle.

Candle ice is typically formed when water with a high concentration of dissolved organic materials freezes slowly, allowing air bubbles to become trapped within the ice. As the ice grows, the air bubbles are released, creating the distinctive columnar shapes.

This type of ice is relatively rare and is considered a type of frazil ice, which is a collection of small, slushy ice crystals that are typically found in freshwater bodies. Candle ice is often associated with the onset of winter and can create beautiful and unique formations on the surface of bodies of water.

Candle ice is not typically strong enough to support weight, so it is not suitable for activities such as ice skating or walking on. It is mainly appreciated for its aesthetic value and natural beauty.
