A 12-cup glass measuring cup is a large kitchen tool designed to hold and measure liquid ingredients, as well as dry ones. Made of durable glass, it is often marked with measurement lines that indicate standard units such as cups, ounces, and milliliters. The transparency of glass allows for easy readability, and its sturdy design ensures that it can withstand both hot and cold temperatures, making it suitable for a wide range of ingredients, from hot soups to icy beverages.
