Take the short bottom piece and place the shell piece (with all the holes) on top. Fill the mold (I find that packing works well for embeds) and then place the tall piece on top and press.

This mold has not been tested with a press but others have used my molds with no issues on a manual hand press, (not pneumatic).

All molds are tested to ensure they allow for easy release. Please be aware that there are many recipes out there and different recipes can make it harder for your bomb to release from the mold. It might take time to find the right consistency that will help with release.
