I have been using resin for over 20 years. By no means am I an expert. I’ve just learned through a lot of trial and error and patience. I also teach high school Anatomy &Physiology. This past year we dissected rats while learning the circulatory system and one of the specimen I was able to isolate veins and arteries to near perfection. Would it be possible and not a complete waste of time to resin the rat? These were animals ordered by the teacher before me so I have no idea how long they’ve been sitting in storage, but they were preserved in formalin. (For further context, formalin is a preservative aqueous solution that is ~40% formaldehyde and 10-15% methanol. The rats have been in storage so long most of them were barely damp when removed from their packaging. And this particular one has been sitting in a storage container since mid-April) I was thinking if I did multiple layers I could add in string and a key to identify parts to make it a study tool. While I don’t want to be the weird teacher that resins the animals, I see this as a great learning opportunity for my students. Plus, I asked what they thought and they loved the idea. Any advice? Ideas? Special resin?
