After eight weeks of restoration, the golden burial mask of King Tutankhamun is back on display at the Egyptian Museum in Cairo, Egypt's Ministry of Antiquities announced on Wednesday.
The intervention was carried out as the long, narrow, blue and gold beard suffered a botched repair more than a year ago.

Braided like a pigtail with the end jutting forward, the beard was unintentionally severed from the chin in August 2014 by workers adjusting the lighting in the case holding the priceless artifact.
Panicked curators did further damage by hastily gluing the beard back onto the fragile 3,300-year-old mask with fast-drying epoxy normally used for wood or metal.
Moreover, the glue was used abundantly, causing it to flow along the beard and chin.

News about the botched repair broke in January, followed by a press conference by Egypt's antiquities ministry. At the news conference German restorer Christian Eckmann told reporters that the mask could be properly restored after removing the glue.
A German-Egyptian team led by Eckmann began the restoration by studying the best materials to remove the epoxy and reattach the beard.
At a news conference on Wednesday, Eckmann told reporters his team resolved to detach the glue using old-fashioned tools.
"We used wooden tools, spatulas, other wooden instruments," he told the Associated Press.

"In addition, we slightly warmed up the adhesive," Eckmann said.
The beard was loose when British archaeologist Howard Carter discovered King Tut's treasure-packed tomb in 1922 in Egypt's Valley of the Kings. It was re-affixed with adhesive in 1946.

During the restoration, Eckmann and colleagues found different, older types of glue in addition to the epoxy resin used in August.
"It's not yet clear to us whether there was just this one attempt to fix the beard, or whether there were several measures between 1946 and today," Eckmann told the German news site DW earlier this month.
One of the top attractions at the museum, Tutankhamun's mask is made of gold and inlaid with stone, faience and glass. It was placed over the boy king's face after his death around 1323 B.C. at the age of 19.
Mamdouh el-Damaty, Egypt's antiquities minister, explained King Tut got his beard back thanks to beeswax, a reversible material also employed by the ancient Egyptians.
"It was prepared well and the beard was attached very successfully," el-Damaty said.
