This work deals with two decorative pointed windows of private property. According to thewish of the owners, an Analysis of the object was made and a Restaurationkonceptdeveloped, wich is going to be accomplished in the laboratories of the Restauration/Conservation of the Fh Erfurt. Goal of the work is the observation of the different Restauration moments, the haestetic and structural Problems of the windows, with a special focus on the chronology of the Restaurations. First of all we have the Analysis of the windows, and especially of the ironframe, the plumbs, the glas and the glas painting.It ́s not possile to discover with certainty the geographic provinience of the windows. According to the Style, they can be put in the second half of the 19 century, during Historismus. Each window has a hand made ironframe with an opening in the right lower part. The frames are stable and in good condition in the core, on the surface, on the other hand,there was a brown corosion inhibitor, wich is now fallen down becouse of the pressure ofthe underlying rust. The frame of one window is a little curved, fact that had had probably consequences on the Glas, in terms of conservation.The openings of the windows can ́t be opended becouse of deformation of the metal and the deposits of dirt in its interstices.The plomblines look complete in all their parts, stable and well preserved. There are no particular signs who could make tink the plombs or wich are new. By putting the two Plomb systems one over each other, it ́s possible to see that they are not build exactly thesame. In the window with the frame bowed to the right side, the plomb system looks brought to the left, for giving a visual contrast to the frame, and let the whole window look straight. The plombs who schould continue straight from the upper to the lower side of the round arches (wich are dividing the windows in two parts) are instead shifted. This happens becouse upper and lower part of the window have to different restauration Hystories. As glass they used clear Floatglass and red onesided cameo glass. Different are the breaks in the Glas pieces in the upper part, where the glas peaces are more fragile. A lot of things changed in time in this part of the window. The medaillons in the middle of the windows had, for example, a smaller diameter than 16,5 cm (like today) and the green leafs were bigger. As the only piece coming maybe from the first wersion of the windows in the upper part we have the orange medaillon with the leaf, who was actually in the past the upper medaillon. One of the blue medaillons seems to be put inside the window from the wrong side. This piece was probably coming from an other window wich didn ́t reached untill now. The paintings of the windows can be divided in two parts, one upper part ist divided from the lower part from two round aches. In the upper part there is a medaillon in the middle surrounded from other three medaillons and three green leaves, in the lower there is avegetal decoration subject. One of the central medaillons has a flower and one a leaf.Paint was put on the glassurface with stanciltecnique and brush, as used colors it´s possible to find every kind of color, beside silver stain. The colors look really damaged because of mistakes during the backing process. The different brown coats in the lower window parts are sign of more Restauration moments. Mechanic and Chemical cleaning are planned. The breaks in the glass must be glued with Araldit 2020. The braeks in the plombs are soldered with tin and the Outshine are closed with putty.
