The Long-Term Efficacy of Conventional Treatments for Bynesian Decay
The efficacy of the conventional method for treating Bynesian decay (formerly known as Byne’s disease) is assessed via a review of the outcomes of two remediation projects after 10 and 22 years. The design and implementation of a large-scale triage plan for an incoming collection is described, and the limitations of diagnostic methods for this form of decay are discussed. Examples of arrested and ongoing decay are illustrated.Abstract

The washing tub. The rubber feed pipe is weighted with a perforated brick and the overflow discharges directly into a sink.

A sample of the reference pictures taken of each lot before treatment commenced. The picture simply records the specimen and its label together, rather than its condition in detail.

Shells in the tub for treatment, positioned with the aperture upwards.

The main drying area, with shells in racks.

Larger shells drying in an old bottle rack.

Medium-sized shells drying in a former merchandizing display for pens.

Smaller lots drying in jars of silicate desiccant.

A lot of four specimens from the second collection, with decay halted by treatment. The largest retains some of its original surface, emphasizing the extent of damage to the others.

A specimen from the second collection, with decay halted by treatment. The characteristic pale areas of erosion are easily visible.

Two specimens from a control lot in the second collection, with decay untreated. These have been stored in a sealed environment, but deterioration has continued.

A specimen from the first collection, treated in 2001. Scarring is visible but decay has not progressed.

Another treated and stable specimen from the first collection, with visible scarring.
