# Recovering Roman material knowledge > EDITORIAL DRAFT — Public editorial drafts. Source inspection and claim standing describe the recorded evidence; they do not establish independent replication or scientific consensus. Lost knowledge becomes useful when a surviving artifact can constrain its reconstruction\. ## Claims The Pompeii investigation found quicklime granules dry\-mixed with pozzolan in a preserved room\-14 material pile at Regio IX\, Insula 10\. [^1][^2] **Standing:** supported within scope. **Kind:** historical evidence. **Scope:** Specific preserved construction site buried in 79 CE\. **Limits:** Relevant primary\-paper excerpts and institutional report inspected\. Live full\-text retrieval remains blocked\; supplements\/raw data were not inspected\. The January 2026 affiliation correction is recorded\. **Claim revision:** claim-pompeii-quicklime@2 **Review:** draft; method: separate agent scoped source cross check; independent review: not recorded. Scope: Independent editorial pass within the same agent team\; not independent scientific validation or replication\. Receipt: docs\/atlas\/source\-review\-2026\-10\-13\.md - Evidence [^1] — supports; locator: Results \/ Evidence of construction activities\: room 14 pre\-mixed pile \(primary publisher indexed excerpt\). Inspection note: Relevant source sections re\-inspected by a separate editorial agent\; no scientific replication performed\. - Evidence [^2] — supports; locator: Uncovering ancient secrets\: intact quicklime fragments in dry material pile. Inspection note: Relevant source sections re\-inspected by a separate editorial agent\; no scientific replication performed\. The investigators interpret the site evidence as supporting hot mixing during Roman construction\. [^1][^2] **Standing:** supported within scope. **Kind:** inference. **Scope:** Studied Pompeii site and materials\; comparison of raw mix and wall\/repair specimens\. **Limits:** The evidence supports this construction practice at this site\; it does not establish a universal Roman recipe or prove that reconstructed mixes meet modern performance requirements\. Full text\/data remain retrieval gaps\. **Claim revision:** claim-pompeii-hotmix@2 **Review:** draft; method: separate agent scoped source cross check; independent review: not recorded. Scope: Independent editorial pass within the same agent team\; not independent scientific validation or replication\. Receipt: docs\/atlas\/source\-review\-2026\-10\-13\.md - Evidence [^1] — supports; locator: Abstract and Results\: dry quicklime\/pozzolan mixture before water\; raw pile and unfinished walls \(primary publisher indexed excerpts\). Inspection note: Relevant source sections re\-inspected by a separate editorial agent\; no scientific replication performed\. - Evidence [^2] — supports; locator: Uncovering ancient secrets\: stable\-isotope interpretation and preparation sequence. Inspection note: Relevant source sections re\-inspected by a separate editorial agent\; no scientific replication performed\. ## Open question How does a reconstructed mix perform against a matched modern material under specified conditions\? This is a research question, not an executed experiment. ## Footnotes [^1]: An unfinished Pompeian construction site reveals ancient Roman building technology. .
