Our Reusable Freezing Bases protect the globe ice lantern balloon from sticks and sharp ice-crusted snow, keep the balloon from rolling around, and aid in the formation of the round shape and open cavity (for light source). For freezing indoors in a freezer at any time of year, use with Small Insulating Disk.
The Reusable Small Freezing Base creates soccer ball-sized globes that can weigh from 8-16 lbs and are designed specifically for the globe ice lantern freezing process. Field tested and perfect for use in cold weather conditions. Use with Wintercraft Biodegradable Replacement Balloons.
For larger globes, use the Reusable Large Freezing Base. Made in USA.
I have used helium strength balloons in the past but never got a round shape. With the base, I got a beautiful shape, and no tipping sideways in the snow.
