Mattone Barile - We suggest using a Sawz-all / Recipicating saw and cut the foam form in a zig-zag motion. It will come out in small chunks, and it will take a bit of elbow-grease, but it should start coming out in large chunks once you get to the middle.
Cortile Barile - Strip all (5) pieces from the foam molds using a handsaw and a chisel (if available). Remove as much foam as possible before assembling.
Mattone Cupola - Try to use a Sawz-all / Recipicating saw to remove as much foam as possible. You may need to use a crowbar or chisel to remove the smaller pieces that don’t want to let-go of the form.
Rules of Thumb when removing the oven foam forms:
You don’t have to get all the little foam balls that are clinging to your oven / oven components as your curing fires will melt these non-toxic foam balls into oblivion.
You are going to use a lot of Lawn & Leaf bags when capturing all of the removed foam. Make sure you have plenty of bags on-hand before you begin stripping the foam off the forms.
If you other question is, “Why does the foam have to be so hard in the first place?”, we encourage you to click on the forum post below that covers that topic.
