We speculated which the paraffin wasn't molten lengthy plenty of for it To combine with the lavender oil and infiltrate the tissue. To test this hypothesis, we tried using adding yet another stage to His’s protocol: re-melting the specimen (that had been dripped in paraffin wax) and afterwards placing it in molten paraffin within the oven at sixty two °C. This made a extraordinary enhancement during the infiltration on the paraffin wax, in addition to a corresponding enhancement in portion quality (Fig. 3c). An alternate addition to His’s protocol was also attempted: an infiltration stage in a very 50:fifty mix of lavender oil and paraffin wax.
