The Processes Involved In Ceramic Restoration And Conservation

By Catherine Perry


The processes that are involved are done for the preservation and the protection of objects that are made of ceramics having historical and personal values. Typically, these restoration and conservation activities are undertaken by convertor restorers. These are the people responsible for dealing the objects having cultural heritages.

The creation of these ceramics came from non metallic material coating and from inorganic material coating productions using the processes of cooling and of heating to create glazes. Typically, the coatings are both sustainable and permanent and this is for the purpose of being decorative and also utilitarian. Ceramic restoration Howell, general treatment, storage, handling, and cleaning are consistent, similar to the glass.

The similarities are those oxygen rich ingredients or components like the silicates. The ceramic conservation is being classified into three different groups. These are the terracotta and earthenware, porcelain and stoneware, and unfired clay.

The restoration of ceramics occurred since the invention of adhesives, patch works, fillings, and reinforcements. The ceramic repair history are ranged from a vast number of methods and as well as methodologies. Here are already new advances today that can be used for ceramic restoration. These would include bonding, dowels, fillers, consolidation, adhesives, and rivets.

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.

The ceramic type is also one important factor that causes the break down. An unfired clay type is unstable and is water soluble. Two common examples for this are the clay adobe and mud. An earthenware is not water soluble and the reason for this is because of a firing process being performed and not allowing a vitreous and an extensive glossy formation into the body. Though not soluble in water, the water is still penetrated to a porous earthenware body.

Glazes are being applied for the purpose of protecting the container from the water. Because of porosity, the earthenware can be receptive to moisture, thus, may create some problems such as breaks, mold growth, and cracks. The mixtures of porcelain clay are being fired to make the surface very hard and non porous. However, materials may sometimes create tiny brittle surfaces, and thus, increasing potential cracks, breaks, and chips.
