We systematically studied the mid-20th century Italian oil panel painting “After Fishing” by Ausonino Tanda using x-ray transmission and terahertz time-domain transmission and reflection spectroscopic imaging (THz-TDSI).
This paper presents measurements of the terahertz properties of the art conservation substance cyclododecane, demonstrating that it can act as a contrast improving agent in the terahertz imaging of concealed wall paintings. Results are presented which show that the terahertz optical properties of cyclododecane are dependent on the rate at which it has cooled from the melt. Based on the results, a...
Cyclododecane (CDD) is a wax-like hexane used as a totally reversible, volatile binding medium for many cultural heritage applications. We investigate CDD using THz-TDS and DFTS, and consider its potential as a contrast enhancing agent for multilayer fresco paintings.
