Cretaceous gnetalean yields first preserved plant gum
Some liquid plant exudates (e.g. resin) can be found preserved in the fossil record. However, due to their high solubility, gums have been assumed to dissolve before fossilisation. The visual appearance of gums (water-soluble polysaccharides) is so similar to other plant exudates, particularly resin, that chemical testing is essential to...Roberts, Emily A. ; Seyfullah, Leyla J. ; Loveridge, Robert F. ; Garside, Paul ; Martill, David M.

An investigation of weighted and degraded silk by complementary microscopy techniques
A number of silk samples, comprising historic materials and modern surrogates, were examined by light, electron and atomic force microscopy, to determine the extent to which such assessments would allow the nature and condition of the materials to be determined. The integrity of these materials had previously been investigated using...Garside, Paul ; Mills, Graham A. ; Smith, James R. ; Wyeth, Paul

Use of near IR spectroscopy and chemo‑metrics to assess the tensile strength of historic silk
Silk is a culturally important textile, found in many artefacts of historic significance including clothing, upholstery, banners and decorations. However, it is a fragile material and is prone to deterioration via a variety of mechanisms, particularly after certain historically common processing methods such as bleaching and weighting. Therefore it is...Garside, Paul ; Wyeth, Paul ; Zhang, Xiaomei

Looking beneath Dalí's paint: non-destructive canvas analysis
A new analytical method was developed to non-destructively determine pH and degree of polymerisation (DP) of cellulose in fibres in 19th–20th century painting canvases, and to identify the fibre type: cotton, linen, hemp, ramie or jute. The method is based on NIR spectroscopy and multivariate data analysis, while for calibration...Oriola, Marta ; Možir, Alenka ; Garside, Paul ; Campo, Gema ; Nualart-Torroja, Anna …

The Formation of Microenvironments in Polyester Enclosures
Inert polyester sheets, such as Melinex and Mylar, are widely used in conservation to create envelope-like enclosures for storing and protecting flat objects (paper, parchment, papyrus, etc.). These materials are known to be chemically stable and present no direct risks to the enclosed items; however, as the films have a...Garside, Paul ; Walker, Olivia

A Systematic Approach to Selecting Inexpensive Conservation Storage Solutions
The appropriate storage of heritage artefacts is vital to their long-term survival, but selecting suitable storage solutions is not always easy due to the number of potentially conflicting factors that must be considered: the method of housing should be compatible with both the objects themselves and with the local environment;...Garside, Paul ; Hanson, Lesley
