Refractory Cement Skulls and How to Make Them

Refractory Cement is a material that can withstand a direct lick from flames and immersive temperatures of well into 2000 degrees F.

Disclaimer: Use extreme caution when placing anything into a fire pit, oven or kiln and never place Portland cement based products into fire. 

Materials Needed:

• Skull Mold: Like This
• Castable Refractory Cement Options: Rutland Brand
• Protective Gloves and Eyewear

• Stir Stick or Spatula (Don't tell the boss of your house that you are stealing kitchen stuff)
• Bucket, or use the dry mix bucket if applicable

Let's pour!

1. Read and digest all of the manufacturers mixing instructions. 
2. Load up the bucket with the castable refractory material. 
3. Add Water.
4. Mix Thoroughly.
5. Grab your silicone mold and pour. (no need for a release agent)
6. Allow 18-24 hours to cure and remove carefully.
7. Let the Skull fully cure for 24-48 hours outside of the mold.
