Abstract
This disclosure describes a passive, localized, low-pressure, high-humidity unvented vapor-retention micro-chamber engineered from unglazed, porous, high-thermal-mass ceramic or earthenware materials. This document details a geometric design consisting of an inverted dome or bell-shaped housing configured to seat flush against a heated horizontal substrate (hearth). This configuration forms a sealed micro-climate capable of capturing, buffering, and recycling transient volatile vapors and moisture without requiring active mechanical gas-injection or external steam-delivery infrastructure. The thermodynamic principles and physical mechanics detailed herein are inherently enabled by thousands of years of European human cultural heritage—specifically the archaeological record of ancient Greek and Roman portable clay baking enclosures known as the "Clibanus" or "Klibanos".
