,... Another remarkable component present in some Rubia species and in particular Rubia tinctorum L. (Madder) is lucidin-3-O-primeveroside. This particular component drives off the varied carpet beetle (Anthrenus verbasci L.) called in dutch ‘Museumkever’ because it is considered a pest because it not only scavenges on other dead insects but also hair, feathers, natural fibers and dead skin, it leaves its eggs in tapestries and woolly objects leaving a black corroded areas when it hatches.
The CHARISMA project will organize next year two workshops devoted to natural organic colorants.
Prior to these workshops an expert meeting was organized at the Netherlands Institute for Cultural Heritage (ICN). The expert meeting was dedicated both on dyeing and pigment preparation from natural organic colorants. The main goals of this meeting were; one to serve as a pilot for the workshops to be held next year in Munich and Brussels, two to share knowledge with the European partners working with these subjects and three to create new reference materials, that can be used as study objects.
ARCHLAB Available facility: ICN Data & scientific records
The access offered by the Netherlands Institute for Cultural Heritage regards information stored in documentation files of the ICN library in Amsterdam. Information concerns typical objects and materials which were previously investigated at ICN, as paintings, textiles, furniture, metals, glass, ceramics, leather, plastics, pigments, binding media, varnish, resin, paper, books, inks, etc., all referred to periods varying from pre-history to date.
Typical information consists of historical documentation, analytical data, images, and reports on samples (including cross-sections). The information is partly registered in Dutch, partly in English, partly in German. An online database is available at http://www.icn.nl/bibliotheek/bibliotheekcatalogus.
Primary task of botanical gardens nowadays is not scientific contribution but keeping visitor numbers. The Netherlands has 112 gardens, of those 10 arboretums and 25 independent botanical gardens three zoo-connected botanical gardens and 4 university gardens. A respectable number of gardens for a small country like the Netherlands. ‘A luxury problem if one or two gardens have to close’...
The CHARISMA project blog allows me to record events, opinions and ideas freely as individual posts without a container to define their scope. This project blog is not only meant as project dissemination, as in the traditional communication point of view, but also as a public message broadcast trying to evoke a direct feedback from the audience.
The task innovative methods and instrumentation for laboratory research is concerned also with organic colouring matters in works of art and objects of cultural heritage. These materials often suffer changes in colour or other forms of deterioration over time. One result of this is that our perception of the object itself may be affected; more prosaically, the colouring matters are sometimes hard to identify. Thus a better knowledge of these materials will help to improve our understanding of these art works and also assist considerably in their conservation
In this new blog I will give you a glimpse into the CHARISMA project aswell as my experiences throughout the project. First of all let me propperly introduce you with the project.
