Lead Transfer Risk from Handling Ceramics with Deteriorated Lead Glazes

Abstract

ABSTRACT The risks of lead transferring to gloves while handling lead-glazed ceramics was evaluated with simple empirical tests using Plumbtesmo test strips. Five lead-glazed ceramics from the Harvard Art Museums, three with deteriorated glazes and two with glazes in good condition, were evaluated along with three controls. The objects and controls were handled using three interaction types (touch and hold, tapping, and rubbing); the presence of lead on gloves was then evaluated using Plumbtesmo test strips. The experiment demonstrated that ceramics with deteriorated lead glazes have the potential to transfer lead to gloves during handling. Collections care staff working with lead glazed ceramics are advised to take precautions during handling and uphold best practices for hygiene to minimize lead exposure.
