Do you want to make those really cool looking fire pit skulls? I'll show you how to make them safely on your own. Great for outdoor halloween parties and really for me, all year round with my haunter friends. Be sure to only use "Refractory Cement" as you cannot and should not use any Portland cement for fire pit skulls, it's dangerous to use. Again, only purchase or order Refractory Cement as it is rated for high heat, up to 2200 degrees. It's typically used to build or repair fireplaces, making pizza ovens and anything to do with fire. You can find Refractory cement at Lowe's or Home Depot and if not in stock you can order online. Please feel free to ask any questions and a like is always appreciated. Happy Haunting my friends!!
