[Histonet] Flat Ice???

[histotech <@t> imagesbyhopper.com]

I much prefer the "wet ice" approach to the more dry variety of the cool
trays.  The "wet" ice gets my blocks colder and I like the fact that it
introduces a small amount of moisture into the already faced block.  My
blocks are not on the ice for long periods of time, so over-saturating them
with water is not an issue.

To keep my trays from growing mountains, I have found that if I fill them up
3/4 of the way and let them freeze and then follow up with the other 1/4
later in the day, I get nice, flat little "ice rinks" that I can lay my
blocks on.  It's not time consuming either, just have to remember to go back
and pour more water on them!  By the way, this works on ice cube trays as
well as steel pans we have.  I don't really care for the pans, but some of
my techs do.  They take a little more work to make them ice rinks.  ;o)

My $0.02.  :o)

For quality assurance and safety concerns, I would suggest moving away from
the "wet ice" and go with a sealed freezing tray. We moved to the small
Histo-Cool ice trays w/ tray.
