Beltane Spell Jar 🌹🌷🌼

Beltane Spell Jar

By: @anenglishwitch​ and @enfant-boiteux

What sort of spell is this: This spell was created to be something anyone could throw together at the last second and not cost a lot to make. It encapsulates the power of the Beltane sun to bring forth a positive summer and ever growing happiness.

What you will need:
- A jar with a lid.
- A ribbon.
- A crystal/crystals of your choice.
- Flower petals of your choice.
- Something to use to write on the flower petals.
- Plant stems.

Here’s a piece of silicon carbide (SiC) from a geology basic course, which I’m taking as an elective (it’s relaxing next to Quantum Mechanics 😄). Because of its high strength and thermal conductivity, SiC has uses in cutting tools, car parts, electric systems, heating elements and much more. One cool example: ceramic plates in bulletproof vests.

fic prompt: Kit stuck his fangs cautiously out of Tin's helmet into the acrid, smoke-filled air.

{{ This was going to be short and cute and then I had to mention I was watching NCIS and someone decided to take that and RUN with it… *taps foot grumpily*}}

Fic under the cut, because it is hella long and *STILL NOT DONE*

Calcium Carbide: Playing with Acetylene flames

Calcium carbide is a chemical compound with the chemical formula of CaC2. Its main use industrially is in the production ofacetylene and calcium cyanamide. 

The pure material is colorless, however pieces of technical-grade calcium carbide are grey or brown and consist of about 80–85% of CaC2 (the rest is CaO (calcium oxide), Ca3P2 (calcium phosphide), CaS (calcium sulfide), Ca3N2 (calcium nitride), SiC (silicon carbide), etc.). In the presence of trace moisture, technical-grade calcium carbide emits an unpleasant odor reminiscent of garlic.

Applications of calcium carbide include manufacture of acetylene gas, and for generation of acetylene in carbide lamps, manufacture of chemicals for fertilizer; and in steelmaking.

The reaction of calcium carbide with water, producing acetylene and calcium hydroxide, was discovered by Friedrich Wöhler in 1862.

Reaction with Water:

CaC2+ 2 H2O → C2H2+ Ca(OH)2

possible incomplete combustion occurring:

3C2H2 + 4O2   2C + 3CO + CO2 + 3H2O

Silicon Carbide (SiC) is a key building block for next-generation devices. It takes features from diamonds, one of the toughest materials in the world, and combines them with features of silicon, our ubiquitous semiconductor technology in electronics to make a very new kind of material for power electronics. SiC can more efficiently handle higher voltage and three times the amount of energy compared to silicon chips, allowing us to run everything from locomotives to planes and wind farms faster and more efficiently.
