The book "Botanical Microtechnique and Cytochemistry" by Graeme P. Berlyn & 
Jerome P. Miksche (Iowas State University Press, 1976; ISBN 813802202) give a 
detailed account of softening wood using hydrofluoric acid - including safety 
precautions for this nasty stuff. Pages 73-74. A sliding microtome is 
recommended. This book also has a good chapter on cutting techniques for 
botanical materials. It is out-of-print but available 2nd-hand quite cheaply, 
eg

[Histonet] RE: peach stone (pit) sectioning?

2015-02-10 Thread Preiszner, Johanna
Thanks everybody for the ideas and the expression of sympathy!

Our conclusion is that it's not possible to soften up a hard fruit pit for 
paraffin sectioning in a standard Histology lab. We never tried celloidin 
embedding, so that's still a possiblility.

The best approach might be a bone or mineral grinder that can produce 
microscopic sections of hard material.

Thanks again,

Hi Netters,

does anybody know how I could soften up a hard fruit pit for sectioning?

Thanks,
