The reproduction of fire-born soot for comparative cleaning tests on heritage objects.

ABSTRACT: This work describes the design of reproducible mock-ups with controlled soot deposition, created to support comparative cleaning tests within the EU Horizon MOXY project. The latter develops atmospheric, plasma-generated, monoatomic oxygen as a cleaning method to remove (amongst others) fire-born soot from heritage objects. A literature review highlights the complexity of soot while revealing a lack of focus on the representativeness of artificial soot in previous studies. We benchmarked two approaches: (I) indirect/cold application of pre-fabricated soot and (II) direct/hot application via ongoing combustion. The results demonstrate that direct combustion yields soot with markedly different physical and chemical characteristics. Chemical analysis (Raman, XRPD, TGA, EGA-MS, XPS) and micros
