ABSTRACT-Cyclododecane (C12H24) is a solid cyclic hydrocarbon that sublimes at room temperature. Cyclododecane has been used increasingly as a temporary consolidant for a variety of weak or friable materials. This study focuses on the physical behavior and working properties of cyclododecane when applied as a solid and in solution to both porous and nonporous substrates. Melted cyclododecane and saturated solutions of the consolidant in hexanes, xylenes, and Shellsol OMS were applied to three different substrates: glass slides, Monks Park limestone, and Ohio Massillian sandstone. Solution mobility, application techniques, and penetration were assessed. Sublimation was monitored in three ways: visually, as a function of weight loss over time, and via gas chromatography-mass spectrometry. This research evaluates the extent of sublimation of cyclododecane from both porous and nonporous substrates and notes the absence of detectable residues. Both substrate porosity and delivery method were found to affect consolidant penetration and rate of sublimation. The practical tests, analyses, and case study indicate the appropriateness and usefulness of cyclododecane for temporary applications on stone substrates.

The Use of Menthol as Temporary Consolidant in the Excavation of Qin Shihuang's Terracotta Army

“…The experiments continued until the sample weights became constant, at which point they were very close to the original weights of the matrices. After sublimation was completed, each of the treated glass slides was washed three times with 2 ml of dichloromethane, and then the dichloromethane solution was analysed by GC-MS to track any possible residue of menthol left on the slides, according to the method reported in the literature (Stein et al 2000).…”

“…In some cases, specific wax could be used, but this solution is not suitable in the case of fragile paintings or varnished layers, where the wax removal could also remove the top layer. Since cyclododecane sublimates at room temperature with continued air exposure, it has been used for more than ten years in short-term applications, as an adhesive [18], a moulding material [19], barrier layer [20], or consolidant [21]. Sublimation negates the need for later removal of the adhesive, and temporary treatment with cyclododecane should not interfere with subsequent study, analysis, or treatment.…”

Cyclododecane as opacifier for digitalization of archaeological glass

“…From their results, it is interesting to consider that CDD does not penetrate and remains in the surface layers, consistent with the level of abrasion of the surface tested. Stein et al [21] applied melted cyclododecane and saturated solution on glass slides and other materials. Sublimation was monitored in three ways: visually, as function of weight loss over time and by GC-MS.…”
