Michael Hengler has worked with multiple color companies in the research and development of colors including Gaffer Glass, Trautman Art Glass, Northstar Glass, and Spectrum Glass, as well as to develop his own colors in glass. This research led him to an Artist in Residence at the Gaffer Glass factory in Auckland, New Zealand. Hengler has written user guides for some of the more complex colors such as Gaffer’s Calcedony, which was originally developed in the mid-1450s in Venice, Italy, and continues to provide beauty, but not without technical challenges. He has also worked with Bethlehem Burners in the testing and performance of colors with their new Champion and Grand torches. Hengler’s understanding of atmospheric chemistry and its effect on color chemistry is instrumental in his ability to render desirable color outcomes.
