Guild notice—Ordering of crystals
While
runic diagrams,
alchemical processes, enchantments and the design of magical
artefacts can be highly optimised, in the end their quality are limited by the materials used in their creation. This is why the choice of those materials is primordial. The
rune guild assists students and staff in the sourcing of minerals and their delivery via
transportation portals, but is not responsible for the way individualS choose to spend their research fund.
Students and staff members are also reminded that they should apply careful consideration before hurrying to order the latest trendy materials for their new project!
How to choose a mineral
What is a crystal?
A solid state material with atoms/molecules/ions arranged in a highly ordered structure, in opposition to amorphous/disordered materials. This regularity allows us to predict the magical properties of the crystals and to use them
safely.
Step 1: Starting material
Start by selecting a material with a few properties of interest—only focus on the properties actually relevant for your project! Remember that
all properties influence each other, and so that magic will be affected by
everything!
Step 2: Mineral selection.
Use the Lerauche formulas to combine different pure materials together to obtain a mineral with the desired properties. Remember that properties depend not only on the combination, but also their proportions and the
crystalline state!
Step 3: Quarry selection
Once you have your mineral, select several quarries where it is mined and order a sample (a sample! not a big order!) to test how the degree and identities of the impurities present in it impact the predicted properties.
Step 4: Forging
Make amorphous material crystalline by
melting and slow cooling—
dangerous artefacts are melted and cooled extremely fast to make them amorphous and neutralise their magic. Materials can also be purified or combined together to form new alloys—but remember that many minerals owe their fancy properties to those impurities!
Material properties to consider
Electrical
E.g. conductivity
Magnetic
E.g. conductivity
Heat
E.g. conductivity, melting point
Mechanical
E.g. ductility,
hardness, internal pressure, density
Acoustical
E.g. absorption, transmittance, reflection
Optical
E.g. asborbance, reflection,
photosensitivity
Chemical
E.g. resistance to oxidation or corrosion
Biologic
E.g. resistance to insect or microorganisms
Price
E.g. abundance, ease of mining
Origin
E.g. avoid Illinie & Rénance
Historical tables
Remember to not reinvent the wheel every time and look at tables of common uses. As you can see, pure metals or metal alloys are the best to work with, so for magic's sake, remember that a chemical crystal is not simply a crystal rock or gemstone and stop defaulting to them!

Examples
The best way to learn is through the study of examples of working and faulty artefacts. You are extremely lucky to have access to the full archives of the runes guild and to the reports all our members have written about their experiments, so take proper advantage of this!
Variable sizes
Transportation portals: enormous size and amount of magic channelled.

Multiple users
Mass-manufactured weapons: fit any user regardless of magical affinity.

"so for magic's sake, remember that a chemical crystal is not a crystal rock or gemstone and stop defaulting to them!" got a laugh out of me. I like how you're continuing the theme with in world handouts, and how we can still get a good glimpse of what's going on politically through them ("avoid Illinie & Rénance")
Thanks! Illunie is basically just England and Rénance is going to be Prussia/Germany XD Little rivalries between countries are always fun :p Q is to blame for the crystal rock/gemstone comment XD He's right that we always have fun with them in fantasy settings and I wanted to twist that a bit here.
