Using Paraloid to label objects is challenging. It requires chemicals, a ventilated work space and time. It can take a lot of practice to become confident using this method but it can provide a very effective object label.
As with all chemicals, it is important to understand the properties and risks of Paraloid B72, Paraloid B67 and Acetone prior to using them.
When working with these chemicals, wear nitrile or latex gloves as they can be harmful to your skin. Additionally, work in a well ventilated space as the Acetone emits harmful fumes. The Paraloid and Acetone must be clearly labelled and securely stored in a suitable chemical cupboard when not in use.
At National Museums Scotland we favour the use of Paraloid B72 as it works best with Acetone. Traditionally Paraloid B67 is also used but its chemical makeup makes it more of an ‘oily’ base that works best with White Spirits. As White Spirits are a degree more dangerous to use than Acetone, we recommend sticking to Paraloid B72 and Acetone where possible.
In the video below, Collections Technician Kelly Rennie demonstrates how to apply a label to a metal or ceramic object.
Always assess the object’s surface prior to application:
