tear mending

Tear mending in modern canvas.
tear in canvas of 6 cm wide: broken thread, deformed canvas, paint losses and pen 

flattening canvas, tear mending, retouching and pen removal              

Before working on the tear of the painting a mock-up was made with similar textile (cotton) and several consolidants were tested. Criteria for the glue were: working method, visibility, flexibility and strength. Glue based on sturgeon glue and Jin Shofu glue was selected. It had the best properties according to the criteria. 
mock-up of cotton: glue, pincet, fibre glass lights 
Placing a milar, board and weights on it flatten the deformation in the canvas around the tear for three weeks. As the textile is of cotton, moist would not be an option. A big cardboard role was made and the canvas was rolled around this face up. This way I could work on the tear from the front side. The broken and stretched cotton threads were impregnated with the sturgeon-Jin Shofu glue. The impregnation improves the strength of the broken fibres. The weave was reconstructed using pincers, needles and surgery instruments.

The broken canvas is re-joined using the glue and the hot needle. From the edges loose wires were taken and impregnated with the same glue. Pieces of 4 cm and 3 cm were cut and glued on the backside in between the wires of the textile to improve strength of the damaged area.

To complete the weave structure at the frontside some toasted fibres (methyl cellulose) were added.

X ray fluorescence

XRF - X ray fluorescence

The Getty Conservation Institute (GCI), the Yale Institute for the Preservation of Cultural Heritage (IPCH) and  Stichting Restauratie Atelier Limburg (SRAL) presented a jointly organised X ray fluorescente ( XRF ) Boot Camp for conservators of art and archeology
 SRAL and the Bonnefanten Museum hosted the workshop and provided paintings to be examined. The workshop took place in Maastricht from 8th to 11th of November 2016.

We learned how to use the safety rules for  XRF - X ray fluorescence handheld in a proper way, how to read the graphs, and what results we can get from it for different disciplines and so much more.  We had great teachers, that were very devoted to their work and giving us the best they could. The organisation was smoots and above all professional! What also means each team of two conservators had their own XRF - X ray fluorescence handheld installation.  But as the name predict.... it was a real Boot Camp, and I needed the whole weekend to reload. But the most important is that the new knowledge is bringing new options to improve my conservation work on paintings. I know where to find my colleagues to discuss the matter or if I need a second opinion or an XRF

karen hearn

Karen Hearn bezocht gisteren 21 september 2016 Middelburg en het Stadhuis op de Dam om het schilderij te bekijken dat Jonson van Ceulen (Cornelius Johnson) in 1650 schilderde van de Confrerie van de Edele Handboog. De confrere gaven haar een warm welkom in de Burgerzaal van het oude Stadhuis waar het schilderij hangt. Mevrouw Hearn is blij met het resultaat, ze kan de schilder techniek van Jonson van Ceulen veel beter bestuderen nu vuil lagen en oude vergeelde vernislagen zijn verwijderd.

Thanks Anna and Lucy for being my colleagues, we were a good team, lots of exchange and changes we shared. Hope to see you another project.
