Fifteen glazed architectural bricks were recently rediscovered in the stores of the Middle East and Egyptian Departments. There are very few examples of glazed bricks from 911-612 BC during the Neo-Assyrian Empire (Tallis, pers. comm. 2016).
1. Dry Cleaning Tests
Molecular traps including: Smoke Sponge and Groomstick were used to attempt to remove the ingrained dirt with little success. The pressure needed to remove dirt from the surface could potentially damage the flaking glaze surface. Dry brushing with a soft, sable brush, removed surface dirt, but did little to reduce staining.
2. Wet Cleaning Tests
IMS caused a white bloom on the surface of the object, which can be seen in the image on the right. No further wet cleaning tests were attempted to avoid this bloom.
