- •
We analyze experimental reconstructions of ancient oil/resin varnish formulations.
- •
We implement analytical protocols applicable on micro-samples.
- •
Numerous oxidized and polymerized compounds are formed during varnish preparation.
- •
The reactivity of linseed oil/colophony varnishes depends on the mixtures' proportions.
- •
Linseed oil and colophony compounds react together to form hybrid adducts.
