Purity of the ice may have an affect on this estimate.
・ Transport ice mugs in an icebox or other cold storage container.
・ Prepare a coaster with a lip, such as a small plate, to place underneath the ice mug so the meltwater doesn't flood your table.
・ Do not use liquids other than water to make the ice mug.
・ Tip: Boil water first to remove impurities that may make the mug weaker.
・ Do not use mineral water, as the minerals in the water may make the mug weaker.
・ Do not refreeze used ice mugs, as it will make the mug break easier.
