Conservators at the Getty Conservation Institute have successfully utilized pulsed-laser ablation to restore a series of heavily obscured Fayum mummy portraits. The technology allows for the removal of centuries of grime and degraded varnish without damaging the delicate encaustic (pigmented wax) paint beneath. This breakthrough is being hailed as a major advancement in the preservation of ancient organic materials.
The process revealed vibrant colors and intricate brushwork that had been hidden for generations, offering new data on the hairstyles, jewelry, and ethnic diversity of Roman-era Egypt. The institute plans to share this technology with museums worldwide to aid in the restoration of other fragile artifacts that were previously considered too high-risk for traditional cleaning methods.
