The Processes Of Ceramic Restoration And Conservation

By Catherine Perry


These processes are being done in order to preserve and to protect the objects made from ceramics that have a historical and a personal value. Typically, the activity of restoration and conservation will be undertaken by the convertor restorer. This person is needed especially for objects being dealt with cultural heritage.

The creation of ceramics are from the production of non metallic and inorganic material coatings by the use of cooling and heating and processes for creating the glaze. Typically, these coatings are sustainable and are permanent for the purposes of decorative and utilitarian. There is a consistency on the ceramic restoration Howell, handling, general treatment, cleaning, and storage, similar to a glass.

These similarities are oxygen rich components or ingredients like the silicates. This conservation of a ceramic is consist of 3 groups. These include the porcelain and stoneware, unfired clay, and terracotta and earthenware.

The restoration of these ceramics had occurred already ever since the patch works, reinforcements, adhesives, and fillings are invented. The history of ceramic repair is being ranged from a lot of methods and also methodologies. Nowadays, there are many new materials and advancements which are being used in the restoration including dowels, consolidation, rivets, bonding, fillers, and adhesives.

The process of consolidation is when the ceramic fabric is strengthened by the introduction of material into a fabric that binds together. The common types which need to be consolidated are the excavated pieces because the bonding of fabrics will be lost due to the absorption of soluble salts and leeching. Rivets and dowels are the physical ways where ceramics are strengthened and reinforced beneath surfaces.

Fillers will be used for the replacement of losses and gaps from materials for support or some reasons. One common material used is plaster of Paris. Some other types of fillers and putties are used as well. The plaster of Paris is a type of material consisting of a calcium sulphate hemihydrate power.

Most of the materials being used in the production of objects eventually deteriorates and these also degrades. The object deterioration occurs and this would lead to the interaction between materials and environment forming the object. However, in ceramics, environmental factors are said to be the causes. There are many ways where in ceramics are going to break down both chemically and also physically.

Another factor that can cause the breaking down of a ceramic is the type. The unfired clay types are unstable and are water soluble. Examples of these are clay adobe and mud. While the earthenware is water insoluble and this is because of the firing process but will not allow a vitreous and extensive glossy formation in the body. Even though it is water insoluble, water can still be penetrated into the porous earthenware body.

A glaze will be applied in order to protect a vessel from water. And since there is porosity, an earthenware will susceptible to a moisture, and thus, resulting to some problems including mold growth, cracks, and breaks. Porcelain mixtures of clay are fired for the purpose of making hard surfaces and non porous. The materials are sometimes creating small brittle surfaces that increase the potential breaks, chips, and cracks.
