On these substrata, the wax remained molten for just a significant time period (25 min and seven min, respectively), but we nevertheless did not attain usable sections (Fig. 3c). When molten paraffin was dripped on to embryos with about 20 µL lavender oil adhering, the paraffin didn't penetrate the tissue. The sections disintegrated when mounted to the slides, almost certainly due to persistence of lavender oil while in the embedding planning.
