Blotter in Pottery and Porcelain for Appraisers and Collectors

The use of blotter in the appraisal and collection of pottery and porcelain involves important considerations. As collectors and appraisers, understanding the value of pieces not only relies on aesthetic value and rarity but also on the quality of preservation. Here is an overview of what you need to know.

What is Blotter?

A blotter is a tool used primarily in the field of paper conservation. It's typically a piece of absorbent paper used to dry freshly applied ink, paint, or glue. However, in pottery and porcelain conservation, blotters can be used in a slightly different way. They're often utilized in plate repair, where the plate is first dampened, then a blotter is placed on the break line to absorb any excess water or adhesive. More recently, conservation blotters have been developed that can absorb and then slowly release moisture, facilitating the controlled drying of repaired ceramics.

Applying Blotter in Pottery and Porcelain

1. Ceramic Repair

After applying adhesive to a broken ceramic piece, a blotter can be utilized to absorb excess glue avoiding it to seep out of the break. This process helps to maintain the original appearance of the pottery item.

2. Moisture Regulation

Some antiques tend to crack when exposed to fluctuating humidity levels. For these delicate pieces, controlled drying using a conservation blotter can prevent further damage.

The Role of Blotter in Evaluating Pottery and Porcelain

An appraiser's job is to evaluate the value of a pottery or porcelain piece. If a piece has been properly repaired using a blotter, it can significantly improve the value of the piece. Conversely, negligent repairs with visible glue can degrade the piece's value.

Importance of Blotter for Collectors

For collectors, using blotters during repair contributes to the preservation of the items’ original aesthetic. The blotter process in pottery and porcelain repair also maintains the integrity of the pieces, ensuring they remain attractive and valuable parts of a collection.

Conclusion

Blotters, while more commonly related to paper conservation, play a significant role in the repair, preservation, and thus valuation of pottery and porcelain pieces. As repair methods continue to innovate, the role of blotters and similar tools will continue to be of interest to appraisers and collectors alike.
