Ice melt, your doing it wrong. What to buy and why.
A 1-inch ice cube at 75°F room temperature (24°C) will take 45 to 60 minutes to melt. A standard 1-ounce cube (30 grams) will take 90 to 120 minutes to melt at the same temperature. The same 1oz (30g) ice cube submerged in a cup of hot water of 185° F (85° C) will take about 60-70 seconds to melt.
