Ultrasonic Misting. Part 1, Experiments on Appearance Change and Improvement in Bonding

An investigation into adhesives to consolidate distemper paintings on canvas

“…In this study, an attempt was made to test different concentrations of solutions prepared with low volatility solvents, and used in up to ten applications to minimize the risk of visible film formations. In the literature multiple applications of dilute solutions were shown to be more effective than using just one concentrated solution (Maheux and McWilliams 1995;Michalski and Dignard 1997;Michel, 2011;Ebert et al 2012). Therefore, although successful methodologies for consolidating friable paint have been based on the use of an ultrasonic mister or similar (Maheus and McWilliams 1995;Dignard et al 1997;Michalski and Dignard 1997;Michalski et al 1998), these techniques were not adopted for these tests as this work required only very low concentration solutions of adhesive.…”

Other methodologies combine the brush application with the use of low pressure tables, but since this investigation intended to find a methodology to deal with large format distemper paintings and in various scenarios, a low pressure table was not appropriate.…”

Micro fading test for textile single yarns: a new methodology applied to the Reformation Tapestry to assess its sensitivity to light

“…In total eight dyed BWs standards are available, with BW1 being the most photosensitive and BW8 the least. Each successive material is approximately from two [7] to three times [1] as lightfast as the previous one. Commonly for micro-fading only the BWs standards 1-3 are used.…”

“…For artwork displays, museums have to meet the most adequate lighting conditions in order to minimise the risk of light damage and, at the same time, allow the visitor to visually experience artworks at adequate illumination. The dilemma in balancing visibility and safeguard ("seeing versus saving" [1]) is a well-known and discussed issue that challenges conservators, curators or museum professionals. Light damage is a consequence not only of the light´s intensity, but also of its duration.…”

Colorimetric evaluation of three adhesives used in the consolidation of contemporary matte paint after artificial ageing

“…Michalski [8][9] focused on resin particle size, using an ultrasonic mister in the consolidation of powdery paint on ethnographic artefacts, both on samples without supports and actual paintings on wooden supports.…”
