2014 Convention - Gerry Gits Challenge
Produce a pyrotechnic device or set of devices, based upon
this year's challenge, titled, "Deep Purple".
This challenge is for everyone to enter, from 8 to 98 and
beyond. Since no Grand Master points are offered, the only
restrictions are those imposed by the Safety Team. Please try
your hand for the trophy and $100 cash prize by entering any pyro from
a single device to a show.
What does "Deep Purple" mean?
The Encyclopedic Dictionary of Pyrotechnics(and Related
Subjects) by Kosanke, Sturman, Winokur et al comments on the
There is no single flame color agent useful in producing purple
flames; however, purple flames can be produced using compositions
that produce a combination of non-purple flame emitters. For
example, a combination of both strontium monochloride (red
emitter, dominant wavelength 636 nm and 100% color purity) and
copper monochloride (blue emitter, dominant wavelength 465 nm and
92% color purity) can be used to produce emissions perceived as
purple. In addition, by varying the ratio of these red and blue
emitters (accomplished by varying the ratios of the two flame
color agents used to produce them) any of a wide range of flame
colors, from violet blue to purplish red, can be produced."
Italics that of Dr. Tilford
In justice to all competitors, young and old, and because of
the inconsistent nature of color perception by the eyes of the
viewer, DEEP PURPLE can be created within a range of color from
violet blue to a purplish red. The pyrotechnic device can be
anything from a smoke producer to a flame, to sparks, and from
one device to a sky full of fireworks!
Notes from the judges: Any shade of purple, or combination can
be used. How about purple smoke? How about our favorite purple
dinosaur, Barney, as a theme? Prince's "Purple Rain"? Multi-break
or petaled shells in gradient deep to light purple? Can a purple
strobe be made? How about making a class C cake that displays
purple rain? What about a purple sparkler or torch? Anyone seen
purple snakes? The possibilities are endless!

The PGI competition team lost a very special member on
Christmas Eve, 2007 with the passing of Chief Judge Gerry Gits.
To honor Gerry's manifold contributions to the PGI competitions
over the years as competitor, judge, and most recently chief
judge, the judges have decided to rename the Judges Challenge
competition as the Gerry Gits Challenge, and the prize to be the
Gerry Gits Memorial Trophy.
