Fireworks. That’s what this is called. This is my second variation using four initial A6 images on an A3 page. I played with the background I did yesterday, with more black ink, more shading, but I added iridescent white to brighten plus thin strips of paper to try and make little explosions to brighten it.
Next step may be to swap a couple of images. I might cut into one or two of them. We will see….
Sodium nitrate, sulphur and carbon. Mixed together make gun powder. That is the explosive mixture they put into fireworks. The ratios of the different elements determine the burning characteristics. Strontium makes red, sodium yellow, copper green, magnesium bright white, other elements make different colours. Cobalt? Possibly blue. The elements burn at different temperatures. Each element, when heated, excites electrons in its atoms. As they cool down again photons of light are given out (emitted). The colour depends on the energy the photons release. Bear with me it gets complicated! In the same way you can tell what elements are in the sun or other celestial objects by their emission lines. If you look at a spectrum (rainbow of colours), given out by the light of the sun there are gaps, these correspond to gases like Hydrogen and Helium.
I don’t know enough science to explain properly.
Anyway the fireworks have stopped so I might go to bed.
And yet, fireworks are going off outside. I feel so sorry for the stray cat living outside in our shed. I hope he’s tucked up out of the cold in the cat box we got him. We tried letting him into the house today because it’s so cold, but our cats objected strongly. They started yowling at him. And as they won’t let me take them to the vets to be inoculated I dare not let him stay inside.
It’s not good to have half an hour of loud fireworks. It’s even scaring the cats inside.
And yet in one country at least they have introduced silent fireworks. Surely we should do the same.
Remember remember the fifth of November, gunpowder, treason and plot….
That’s the rhyme we learn as children in the UK to remember the date of the gunpowder plot when Guy Fawkes tried to blow up parliament in the reign of James 1st I think? Hopefully no one will try to do the same thing again.
There is a party mood around this time of year. People build bonfires and place effigies of ‘Guy’ on them. (Children go out and collect change from people by making their own Guys and asking for ‘a penny for the Guy’.).
Fireworks are set off to celebrate. Nowadays people tend to go to organised displays. There sometimes are private bonfire parties and you can buy very big fireworks. However there are quite a few injuries every year with burns being a major factor.
I remember spinning Catherine wheels, volcanoes, bangers, rockets and roman candles and other old favourite fireworks from my childhood. My best memory was writing my name with a sparkler (a metal stick with a burning chemical on it that sparkled when you waved it about when it was lit).
Food was jacket potatoes cooked till the skin was flakey and black, with lots of butter and salt. Fried onions and sausages and tomato ketchup.
We always built the bonfire high over several days. We didn’t know you were supposed to build it on the day as hedgehogs could be hibernating under the pile of wood.
Good memories. Now I stay in and keep the cats safe and secure.
