<p class="MsoNormal">Hi Dee, <o:p></o:p></p>

<p class="MsoNormal">I am trying again because, apparently, my response is being held by the moderator due to exceeding the permissible file size – I had attached some references but will replace these with links now.

<p class="MsoNormal">I had not yet heard of this product but it appears to be ethanolamine thioglycolate which is based on a treatment described by Lorraine Cornish (<a href="https://www.palass.org/sites/default/files/media/publications/palaeontology/volume_27/vol27_part2_pp421-424.pdf">https://www.palass.org/sites/default/files/media/publications/palaeontology/volume_27/vol27_part2_pp421-424.pdf</a>,
). This treatment is still in use today, although alternatives exist (e.g., ammonia –

<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In this context a new publication (<a href="https://www.tandfonline.com/doi/full/10.1080/00393630.2021.2015947">https://www.tandfonline.com/doi/full/10.1080/00393630.2021.2015947</a>) may provide some answers on preventing damage to mineral
and other geological specimens to avoid having to subject them to treatment – although this won’t save them from historic damage of course, nor resolve the issues you mention if environmental control is not currently ideal. But treating specimens and then
placing them in the same poor environments has considerable resource implications.

pyrite disease (<a href="https://www.zoicpalaeotech.co.uk/products/pyrite-stop" title="https://www.zoicpalaeotech.co.uk/products/pyrite-stop"><span style="font-family:"Arial",sans-serif;color:blue">www.zoicpalaeotech.co.uk/products/pyrite-stop</span></a>).
As my experience with mineralogical collections is quite limited, I would like to get thoughts from colleagues on the listserv about the product's suitability for use with pyritic materials in museum mineralogical collections, particularly where both environmental
control in collections storage and laboratory ventilation are sub-optimal. <o:p>
