Seashells
I spent more than a couple hours breaking up some shells to use in the woodfire. The jar on the right is to show what they look like before breaking them up. The ones in the jar are a little thin to use for woodfiring. It's a little wasteful to use a whole large shell to resist the ash. I broke the shells into 2 or 3 pieces each. It's not easy to break the shells up without turning them into a pile of gravel. I start by using a pair of pliers to bust the bottom of the shell (hinge) off. Then, I use a hammer to whack a screwdriver to split the shells into pieces. Wear safety glasses and gloves. Sharp bits of shells will be flying everywhere.
