<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;">I have never used Greenfix which is a glyoxal-based fixative but I am unsure of whether it brings about a fixation reaction - chemical change so that protein molecules are more stabilised. If so, then a transfer to alcohol should do no harm in theory. <div class=""><br class=""><div class="">For the deer leg I would advise a glycol / phenoxyethanol-based preservative, there are several at least and that will solve the problem of flexibility. </div><div class=""><br class=""></div><div class="">Wait until there have been more responses from those who may have used Greenfix. <br class=""><div class=""><br class=""><div class=""><span style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);">With all good wishes, Simon<br class=""><br class="">Simon Moore MIScT, RSci, FLS, ACR<br class="">Conservator of Natural Sciences and Cutlery Historian,</span><br class=""><br class=""><a href="http://www.natural-history-conservation.com" class="">www.natural-history-conservation.com</a><br class=""><br class=""><span></span><br class=""><span style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);"></span><span style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none;"></span><span><img apple-inline="yes" id="84460FB2-8925-4288-A4F8-B512A5557950" src="cid:3543D570-FCD3-4F5F-B04C-2A6D3A8D9E27@home" class=""></span><span><img apple-inline="yes" id="34C5921F-3A42-463C-8C64-05FC4E1EDE09" src="cid:44ED9140-C81F-497F-B52B-A41A76C7F679@home" class=""></span><br class=""></div><br class=""><blockquote type="cite" class="">On 16 Feb 2022, at 09:08, Claire Smith <<a href="mailto:c.e.smith@pgr.reading.ac.uk" class="">c.e.smith@pgr.reading.ac.uk</a>> wrote:<br class=""><br class="">Do any of you use Greenfix as a long-term storage medium in your fluid collections?<br class="">We have a grand total of ten specimens stored in Greenfix since 2014, two of which have almost completely evaporated.
