Hi folks, Last year, I mentioned I was developing a method to create mineral mounts that could be used to teach optical properties in thin section. The paper I wrote on this was recently accepted by American Mineralogist, but it will be quite some time before it appears in print. If you’re interested in seeing the method, Am Min posted the preprint online at https://pubs.geoscienceworld.org/ammin/early-publication <https://pubs.geoscienceworld.org/ammin/early-publication>. Just search that webpage for Kohn, and you’ll find it. Although the technique was designed for mineral separates, I was able to use it to preserve very delicate textures for fibrous zeolites, too. In fact, many of the Perkins et al. (2024) zeolite thin sections were made that way (see https://optical.minpet.org/2-quartz-feldspars-and-other-framework-silicates/#26_Zeolites <https://optical.minpet.org/2-quartz-feldspars-and-other-framework-silicates/#26_Zeolites>). If you have any difficulties downloading the Am Min preprint, let me know and I’ll send you a copy. All the best, Matt Note: While I may send email outside of regular business hours, I do not expect the same from others. ******************************************************************************************************************************* Dr. Matthew J.
