Hello! I am attempting to preserve just the legs and feet of a small song bird in standing and perching pose. Eventually I will be 3D scanning and / or using them to make a silicon mold from. So far, my internet research has led me to do the following: 1. Remove the legs from the fresh body, just above the joint. 2. Pose them in a standing position using wire to attach them to a small piece of cardboard for support. 3. Completely cover them in Kosher salt for 4 days in a sealed container. 4. Swap the Kosher salt out for iodized table salt and let sit for 3 more days for a total of a week in salt (I swapped because I read on one post that it must be iodized salt... but later on another thread I read that iodized salt is the worst thing you can do... so I'm very confused.) 5. Remove them from the salt today. Overall they seem to have dried out well and have no moisture left. However, they seem to have lost their volume (Which to be honest makes sense since I've sucked all the moisture out of them). Additionally, the loss of volume has also caused a lot of the details such a foot pads and creases on legs to diminish, which is what I was hoping to preserve for the purpose of 3D scanning and mold making. I feel like I'm missing a step or three. Are the feet considered preserved now? Is there something I do to help restore the volume to the piece after drying out? Have I ruined them? I'm hoping to figure this out before I start on the feet of a chicken that are currently in my freezer waiting for me to figure this out. Doing justice to the creature that is so graciously letting me use their legs in my art is important to me. Thanks in advance for any advice you can provide. I really appreciate it.
