Hi Ginevra Sounds very familiar… I use the microtome only for taking microscopic photographs – either for anatomical measurements or for publication-figures. For all other uses I use razorblades by hand and without embedding. If you have to make thinsections for photographs – maybe try the procedure in the attachment.

März 2017 23:27 An: [log in to unmask] Betreff: MOUNTING-EMBEDDING OF WATERLOGGED WOOD Hello, I am a PhD student and I am working with some samples of waterlogged woods from a Roman archaeological site in Lisbon. The fragments of wood are very spongy and is impossible to prepare any kind of section using a razor blade. I have the opportunity to use both a cryotome and a microtome. I read some articles where is strongly advised to embedding the sample of wood using CARBOWAX and than to prepare section using the microtome. I would like to know whether or not exists a protocol to prepare the sample. I am open to any kind of advise or different methodology. Best regards and thank you very much in advance. -- Ginevra Coradeschi Hercules Laboratory, University of Évora, Portugal
