There are various kinds of ornate picture frame. They include hand carved decorations made from solid lumber, hand made composition decorations applied to a pre joined frame, bulk manufactured compo frames and mechanically embossed lumber ornamentation. Frames are made from solid lumber for several 1000 of years. You will find illustrations from Ancient Egypt and there is a solid connection between the Ancient Rome Catholic Church and elaborate framed religious artworks for at least the last one thousand years. The Egyptians discovered ways of applying gold leaf to lumber by using a bole made from Armenian clay. The frames were frequently designed by the artist in discussion with the artisan framer.
In several illustrations the framework was made prior to the art being painted. The carved frames were frequently gessoed with the same mixture of rabbit skin adhesive, water, deadened plaster and chalk. Framers wanted to make ornate frames faster and also wished to repeat a specific design to conserve time from the laborious job of sculpture so they developed a mixture called Compo. The arrangement might be made in a big batch and kept as bricks to be later warmed and reactivated in a pliable molding compound. Decorations could then be carved once and after that either by making the carving as an adverse mold or by copying the decoration through the use of molten shellac or molten resin be duplicated by pressing the hot compo into the form and after that applying the flexible decoration to the frame before it’d cooled and set hard.
Many reproduction frames continue to be made today by the structure technique. Modern use of silicon method allowed easy replication of carved decorations although there are various practitioners of the old methods utilizing conventional components. The ornate swept frame where a decoration is applied to a wooden base and after that gilded is a very common example. An imitation gold made from a combination of copper and nickel. The schlagmetal is applied utilizing an oil gilding technique where a slow drying paint is applied to the prepared framework and after that following a set time right before the varnish is completely dry the leaf is applied to the surface. Most industrial gold frames are made with synthetic gold leaf like schlagmetal due to the cost effective of the material and a swift implementation of the finish and preparation of the underlying lumber. Modern ornate gold frames that may be obtained in lengths are often made by a physical compo machine.
