[Histonet] problem eyes

[Anne van Binsbergen]

do a search on the histonet archive
i posted a method quite a few years back
processed and cut eyes (human and piggy) on a daily basis for almost 10
years
go find it - it may help

patience, determination, thicker sections, 2 x pre-float out first on dist
water and then very dilute alcohol to manually tease out the crinkles, then
a gentle float on low ttemp water bath
if its too hot and the sections are too thin they will shatter on the warm
water
plenty of wax support in the block (use a bigger mould when you embed)

i am on vacation and saw this post by chance

unable to reply in too much detail

good luck
