Everything is a substance. Radioactive chemical smog is a substance.
To answer the intent, however, ice is formed when water gets cold enough to form crystals. It is unusual in that this solid form attains greater volume than it's liquid form as a result of that crystalline matrix.
This was used extensively in the ancient quarying of rock. Water was poured into cracks in the stone in freezing weather, and the water froze and expanded it would force the crack apart and split the stone.
In a solution in which it cannot separate, this crystal formation does not occur, at least not correctly. More often, the pure water will freeze at a different temperature than anything mixed with it, therefore separating itself and floating in the remaining liquid.
This was a primitive way of distiling alcohol in cold climates. Apple cider, etc. was left outside overnight and the ice was removed in the morning, leaving behind the concentrated drink.

Is ice in a glass of water a substance or mixture?
if you are comparing the water and Ice then it is neither. they are both the same.From one point of view you have a mixture - even though they are the same - one is in the solid state and the other is in the fluid state.From another - its an homogeneous substance since they are the same element.To be literal as to your question: which is about the ICE itself and the water is not actually the substance in question. With that then the Ice is a substance and as long as it is ICE is is not mixing with the water. When the state changes from solid to liquid the melted liquid has become the other substance and is no longer ICE.
