Each block was embedded in a suitable medium, which when frozen would provide stability for the cutting process
Once the gelatine was solid, the mold was transferred to the Ultra Freezer (-85°C) for at least 12 hours. The mold was then removed and partially disassembled. Mold was finally reassembled, with another layer of gelatine siphoned into it. When the final layer was solid, the mold was again transferred to the Ultra Freezer for complete freezing and storage.
