I fired the three pieces one at a time in the kitchen oven. A couple hours at about 250 to drive out moisture and about 5 hours at 500 fahrenheit. The bottom section developed a small crack. This is the only section that didn’t have extra re-bar in it. I didn’t add the rebar because this section doesn’t move and isn’t lifted. I might regret that choice.
The other two came out great. Here they are bolted together.
