We utilised cork or Bakelite bases (gutta-percha couldn't be received). On these substrata, the wax remained molten for just a significant time period (25 min and 7 min, respectively), but we continue to did not attain usable sections (Fig. 3c). When molten paraffin was dripped onto embryos with around 20 µL lavender oil adhering, the paraffin did not penetrate the tissue. The sections disintegrated when mounted around the slides, possibly because of the persistence of lavender oil while in the embedding preparing. Just a number of shreds of remaining tissue were being sufficiently sectioned. Blotting absent the surplus lavender oil attained a modest improvement in a few sections, but still did not yield acceptable sections.
