Analyses Physico-chimiques des peintures<\/h2>\n

 <\/p>\n

Men\u00e9es durant neuf ann\u00e9es, les fouilles de la basilique Notre-Dame de Tongres<\/strong> ont mis au jour une quantit\u00e9 importante de peintures murales fragmentaires. L\u2019\u00e9tude globale de ces enduits a fait l\u2019objet d\u2019un march\u00e9 public lanc\u00e9 par l\u2019Agence du Patrimoine de Flandre, attribu\u00e9 au Centre des Peintures Murales Romaines de Soissons.<\/p>\n

L\u2019\u00e9tude a permis de traiter la globalit\u00e9 du mat\u00e9riel, r\u00e9parti en trois cat\u00e9gories. Celles-ci comprennent les enduits in-situ<\/em>, les enduits fragmentaires effondr\u00e9s en place et les enduits fragmentaires issus de divers remblais.<\/p>\n

Dans le cadre de l\u2019\u00e9tude technique de ces enduits peints antiques, vingt-cinq \u00e9chantillons de peintures murales ont \u00e9t\u00e9 examin\u00e9 en stratigraphie. Ils ont \u00e9t\u00e9 analys\u00e9s par spectroscopie de fluorescence X<\/a> (SFX), microscopie Raman <\/a>et spectroscopie infrarouge <\/a>(IRTF).<\/p>\n

L\u2019objectif des analyses \u00e9tait de d\u00e9terminer la composition des couches picturales. Cela passe par la caract\u00e9risation des pigments utilis\u00e9s, des charges min\u00e9rales et d\u2019\u00e9ventuels liants organiques.<\/p>\n

Le CARAA a permis de caract\u00e9riser la palette des pigments et charges utilis\u00e9e \u00e0 Notre-Dame de Tongres. Ainsi, on note l\u2019utilisation de pigments de type calcite, h\u00e9matite, minium, cinabre, goethite, bleu \u00c9gyptien, terres vertes, …<\/p>\n

Ces identifications ont permis de mieux appr\u00e9hender la technologie \u00e0 Tongres. L’\u00e9tude a notamment port\u00e9 sur les attributions d\u2019ateliers, les couleurs originelles et les alt\u00e9rations subies par les peintures lors des nombreux incendies et d\u00e9gradations du site.<\/p>\n
