This used book is in Good condition. This book came from a library. Khalili's classic, authoritative manual describes how to build arches, domes, and vaults with earth, as well as techniques to fire and glaze earth buildings to transform them into ceramic houses. This newly revised edition also provides insight into the latest response by building officials to Superadobe or earthbag technology (structures of sandbags and barbed wire), a patented system that is free for the owner-builder and licensed for commercial use. Nader Khalili's ideas on ceramic houses and earth architecture have been published by NASA and utilized by the United Nations, and have passed building and safety tests in California. This new edition is now in its fifth printing.
