Bucket Heater European Skull Mount

Using a bucket heater (#ad) to do a European skull mount.

For many years I have been doing the maceration method to clean my deer and elk skulls for European skull mounts. Here is a detailed blog entry on my old DIY European Skull Mounting Process that you should read as it has details on the plaques that I make to put them on the wall. I have liked this method because it doesn't damage the skull like boiling them does. Boiling skulls warps the bone, tipping the nose upward and I have yet to see a boiled skull that didn't have the delicate nose bones destroyed. The methods I use don't warp the skull and keep all of the delicate nose bones perfectly intact.

Here's what you will need. 

  1. Access to running water with a hose
  2. Five-gallon bucket for deer a larger container for elk (I use an old cooler)
  3. Access to power.
  4. 1000W Bucket Heater (#ad)

Here's my process of cleaning the flesh off the skull.

  1. Skin the head and remove the eyes and lower jaw bone
  2. Fill the 5-gallon bucket with water and have the bucket tipped slightly so overflow water will run over one side
  3. Place the 1000W Bucket Heater (#ad) in the bucket
  4. Place the skull in the bucket
  5. Get a hose to trickle water as slowly as you possibly can and place it dripping into the bucket
  6. Continually check the water level and wait for three days
  7. Pull out the skull and use needle nose pliers, running water and a knife to clean off any flesh.

Bucket Heater European Skull Mount

This is the Bucket Heater (#ad) I use to do European skull mounts.

What the bucket heater does is it slow cooks the skull. It has a thermostat the keeps the water temperature around 150° and towards boiling but it does not heat it to the point of boiling. This method is nice because if you get your skull in shortly after harvesting your buck the process will not create any unpleasant smells. I like that there is no bacteria involved that stinks and could get on you. 

While the skull is cooking for three days you will want to monitor that the water stays trickling into the bucket. If you are doing this when the temperatures a well below freezing at night you will need to adjust the flow accordingly and monitor that the skull stays submerged. Try to keep the water just dripping into the bucket as not to lower the temperature of the water too much.

After three days in the bucket, all of my deer skulls have cleaned off very easily. Elk have taken five days because I have to use a larger container and can't get the water as warm.

Here are a couple of other steps I like to take after cleaning the flesh off.

Removing any leftover grease.
After the flesh is all off I will clean the bucket out, fill it with fresh water, place the Bucket Heater (#ad) and skull back in it. I will have the hose trickle water in the bucket and I will add some soap to the water in the bucket. I will leave the skull in the bucket with the soap for a few hours. This step helps remove any access oils that may still be in the bone. The Bucket Heater (#ad) has been removing oils all along but this just helps to be extra sure that you have removed any oil in the skull. The reason I like the bucket slightly tipped (step #5 above) is so that oils that float to the top drip over the edge of the bucket for the 3 days of cooking the skull.

Bleaching the skull white.
To get the skull bright white I will use 40 or 50 volume creme developer (#ad). Right after taking the skull out of the bucket of water I carefully use a paintbrush and brush it all over the skull but not on the antlers. I will then let that sit for a few hours. After it has sat for a couple of hours I will clean out the bucket and place the Bucket Heater (#ad) and skull with the developer on it in the bucket. I will then fill the bucket up with fresh water up as high as I can until it almost touches the antlers. The top of the skull will not be submerged but most of the skull will be. I then turn on the Bucket Heater (#ad) and heat the water for an hour. I do not trickle water into the bucket during this step because it will raise the water level over the antlers and get bleach on them. The heat of the water mixed with the bleach of the developer in the water bleaches the skull white really fast.

Mounting on the wall.
I like to make my own plaques for mounting them on the wall. That process can be found in this article: DIY European Skull Mounting Process.
