Portable Antiquities Scheme and our 3% Solution

New Product

Preserving your finds (excluding potential treasure items) is a very personal choice. Some use crystalline wax (or an alternative) to seal, polish and protect their coins and artefacts, others use beeswax and some even use hairspray. A large majority prefer to just leave them as they found them.

We've expanded our range to include a 3% solution in 50ml, 100ml and 150ml variants.

Why 3%?

In 2018 the Portable Antiquities Scheme (PAS) produced a document titled 'Conservation advice for finders', which offers various suggestions and guidance for preserving finds. One product mentioned is Paraloid B-72, the raw material used in our products.

The PAS guidance discusses a 3% solution as a coating and a 15% solution as an adhesive for joining broken artefacts. We decided to offer the 3% solution for customers who prefer a lighter concentration.

The Finish

The finish of preserved items is important, and some people prefer a matt or satin appearance, which the 3% version can provide.

We also provide a 10% version which brushes on easily and evaporates leaving a coating of Paraloid B-72 with a soft gloss finish. It provides a useful balance between protection and finish.

Our 20% version is suited to artefacts or coins that require more surface consolidation, such as an artefact with a crumbly, delicate or powdery finish where handling could potentially cause further damage. On coins, the 20% concentration can also produce a glossier finish.
