While looking for YouTube videos on how to create flame patina on copper, I came across Czech metallurgic artist Ladislav Vlna. He creates distinctive portraits on a steel canvas using flame from blowtorches. Ladislav uses differing temperatures from the heat of the torches to create a range of colors on his artwork. The artist has been perfecting his technique for over 16 years. And his works have sold for up to $9,400 US.
To watch Ladislav at work on one of his masterpieces, Turkish Public Broadcasting has a YouTube video . Learn about about the artist's technique in an article by Reuters
