Hello, I am in need of some advice or direction to proceed. I attempted a whitetail deer maceration project recently, and it is not working. I think the skull has been in the water for close to a month now. Most of the flesh has been removed, but the rear of the skull near where the lower jaw connects and around where the spinal cord enters the brain cavity still have alot of soft rotted meat on them. Some areas are very stuck to the skull and will not pry off easily with a knife or scalpel. Almost like the membrane is glued to the skull. Here is the process I followed maybe someone will notice a mistake. I cleaned the skull (probably more than I needed to) removed eyes, jaw, fat behind the eyes etc. The skull was sitting out in my garage for a couple weeks at below freezing temperatures. I then brought it in the house for a day to thaw it. I placed it in an insulated bucket in the garage with just plain tap water and an aquarium heater. The water was 108 degrees for two weeks. After 4 days I changed half the water.(which may have been a mistake), and when I pulled it out after a week nothing really rinsed off with a hose. I learned that 108 degrees was a bit too warm so on December 18th I changed the water and turned the temp down to about 85 degrees, and added some small chunks of raw meat. After a week or so I checked it again and there was no progress, It was still not clean and nothing rinsed off since the membrane seemed to be stuck on the skull. I then thought maybe the wrong bacteria got started and stopped the maceration. So I dumped the water, washed my bucket out with soap and water really well, soaked the skull in clean water overnight, and then returned the skull to the insulated (cleaned) bucket at 85 degrees for two weeks, and added some small chunks of meat. I pulled out the skull this morning and nothing had changed. The skull has been in the water for over a month now and it has made no progress since the first time I pulled it out of the water after 4 days and changed the water. I thought that could have been the problem so that is why I attempted to start over with the clean bucket and fresh raw meat, but it didn't make a difference. I have searched the archives here extensively and have not found anyone else with a similar problem. Any advice would be appreciated.
