The Conservator's Cookbook is a collection of practical, step-by-step guides outlining how to prepare various solutions, adhesives, gels, and other mixtures used in heritage conservation. While most conservators learn the chemical rationale of solution-making during their training, the actual process of preparing these compounds can be neglected or eventually forgotten. This "cookbook" provides a non-exhaustive and adaptable resource, compiling practical recipes from across heritage conservation literature into a single volume. Drawing from techniques used in furniture, paper, paintings, textiles, and other conservation specialisms, each "recipe" in the Cookbook begins with a short summary of key chemical ideas, before relating step-by-step instructions. The solutions range from simple dissolutions (adhesive resins), to more complex cleaning systems (utilising surfactants, chelation agents, and enzymes) and gelled carriers. Each "recipe" is followed with collections of technical data which help to bridge the gap between chemical understanding and practical application. The Cookbook also provides important notes on health and safety and laboratory best practice, addressing some common misunderstandings and encouraging more sustainable approaches. Intended for the experienced professional and conservation student alike, The Conservator's Cookbook is a crucial reference work that provides a starting point for practical experimentation and interaction between different conservation specialisms.
