Natural Sciences

O’Sullivan Conservation specialises in the preservation of cultural heritage objects and artwork crafted from natural materials like bone, shell, mother-of-pearl, and plant fibres. These organic materials can be fragile, making their conservation a distinct challenge. Our dedicated team has extensive experience in working with these delicate materials, employing a minimal conservation approach to ensure their longevity. 

We have a thorough understanding of a range of natural materials and the unique challenges they pose, including their susceptibility to environmental factors like humidity, light, and pests. We understand the care required to mitigate deterioration, damage, and degradation, from undertaking thorough condition assessments, to implementing meticulous cleaning and restoration treatments, to providing recommendations for storage and display.
