My dome is done and i have it wrapped with foil, i have the chicken wire but i cannot find any vermiculite or perlite in this country at all, I have gone to every plant nursery building store everywhere and nothing, not to mention i asked if there were any fire proof or temp resistant insulation materials i could use and still nothing. Does anyone one know any materials that I can use for insulation in the dome? I have all the components except the insulation and the blanket and vermiculite seem to be out of my reach here in Santiago. Can anyone give me an idea fast. I don't want to lose all my heat every time i fire the oven.
