Abstract
A method of providing a specimen section embedded in a section of paraffin wax includes providing a mold having a cover and upper and lower portions with a body of solidified paraffin wax therein, heating the paraffin wax while in the mold until it becomes molten, removing the cover of the mold, placing a specimen in the liquid paraffin in the lower mold portion, cooling the paraffin until it becomes a hardened body, and removing the lower mold portion to provide a hardened block of paraffin secured to the upper mold portion with a lower end portion extending below the lower end of the upper mold portion and containing the embedded specimen. The upper mold portion with the paraffin block is disposed within a microtome so that one or more slices of the hardened paraffin block may be cut therefrom to provide a slice of the block which includes a section of the embedded specimen.
