The shape of the bottom of Forge’s ice gems will vary. An ice gem does not have to be flat in order to create a sphere with the Forge Clear Ice Press.
If the bottom of the ice gems are concave, try increasing the size of the ice gems. To increase the size:
1. Press and hold “Ice Making On/Off” and “Activate Cleaning Cycle” buttons at the same time. The display screen will then display a scale of 1-7, with 1 being the smallest and 7 being the largest gem size. (The default ice gem is a size 4.)
2. Cycle through the size scale by selecting the “Activate Clean Cycle” button.
3. Once your desired gem size is determined, press and hold both buttons to select and exit. Note that increasing the size of the ice gems will also increase the time it takes Forge to make ice.
Changing the size of your ice gems is only possible when Forge is not in ice making mode.
