Fireworks

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.

Sunset over Alsager Mere

It doesn’t get more spectacular, looking out over the mere as the sun set, changing from orange and blue to a peach and rosy purple. It was a long day but enjoyable.

It’s interesting that on Mars the sky is red with dust in the daytime, then the sun sets and the sky turns blue.

I live on the wrong side of the hill so that I don’t get to see sunsets very often. It was lovely to see this.

Sunrise this morning

The sun crept up and sideways,

Falling West And South,

Skirting tree branches and

Hopping over leaves.

Each minute, slightly higher,

Each second slightly across to South.

As the Sun reaches its Zenith

It falls behind low clouds,

Grey mist rising,

Now its afternoon.

Already going dark and freezing,

Sunrise forgotten in the crepuscular light.

 

 

Red morning sky

I woke up to this red sky about half an hour ago. The sky is now more yellow and the sun is above the horizon. The light is streaming through the leaves and lighting them up. The red sky does not bode well for later on… Red sky in the morning shepherd’s warning (or sailors), but it certainly makes a breathtaking sight right in the heart of the city.

Blue green yellow… and a bit of orange.

Have you noticed a theme? There are yellows, blues and greens floating around my last few posts. Maybe I’m heading towards spring colours to avoid the start of autumn turning into the drab greys of winter.

Two of these pieces of glass are replacements for the bright yellow bowl that the cats broke, let’s see how long they last!

I’d like to go back in time sometimes. There are so many things in the world that are going wrong. We don’t need to live in interesting times x.

Metal working tools…

And other images from the Forge at Etruria. I was there today and took a few photos in the beautiful mid September sunshine we had today.

When the sun is bright and low it casts deep shadows and picks out intricate details that you might otherwise miss.

The glow from the flames of the Forge added to the atmosphere, you can almost feel the heat coming off those flames.

The Forge is the domain of Sculpted Steel. You can see demonstrations of the blacksmiths work on open days at Etruria Industrial museum.
