Some like it hot!

Previously we looked at
the origination of fireworks and
although they have been used for centuries it’s only in relatively recent times
the variety of colour has been introduced into display fireworks. Back in
the day yellow and orange were the only colours that could be produced, later
chlorate’s were added producing greens and reds. That was it, the gauntlet had
been laid and from that point the quest to produce louder and more
colourful fireworks had begun.
Better colours fall to 2 main mechanisms;
Incandescence and Luminescence
Incandescence, in simple terms, is the light produced
from heat - making the substance grow hot and glow. During the changes in
temperature it results in the release of infrared, then red, orange, yellow and
white light.
Deep greens and blues require much higher temperature. They are produced
through the mechanism of luminescence, light produced through
energy source. More complex maybe, but this breakthrough has meant pyrotechnics
have achieve those allusive blue colours!
Naturally this process incurs more cost which is why display
fireworks containing blue colours are more expensive. We stock a fantastic
range of all year round fireworks, containing all manner of colours at
very competitive prices. To see our full range why not head over to our website or
