2025 Poster Session

Kashrut is a set of dietary laws concerning with the foods that Jewish people are permitted to eat and how those foods must be prepared according to Jewish law. When treating Jewish objects, especially those used for traditional ritual, one must consider the sources of conservation materials to respect the standards of kashrut. Although treatment materials are not intended for consumption, this process and understanding is essential to respecting Jewish culture in tandem with conservation treatments. 

Plant-based materials are always kosher, fit for consumption or use. Additional concerns arise when considering animal-based products, as these are much more restricted under the laws of kashrut. In particular, gelatin is a common conservation material in almost all specialties. It is a versatile material and can be used as an adhesive, consolidant, or sizing. As an animal derived product, it is essential to understand the sources and preparation of the gelatin to ensure it complies with the laws of kashrut. 

This poster will introduce conservators to the framework of the laws and contemporary practice of kashrut with the intention that they may reference and consider it in the process of choosing materials for treatment.
