Chromatic Calibration: Bio-Optic Killshades
Craft each of the following goggles listed below.
Chromatic Calibration: Bio-Optic Killshades is a 5-point crafting achievement that rewards cosmetic appearances for all seven Bio-Optic Killshades by crafting each one using Cataclysm Engineering (75).
Learn All Seven Patterns
Visit the Engineering trainer to learn all seven goggle patterns — Alliance players go to Lilliam Sparkspindle, Horde players go to Roxxik — you need Cataclysm Engineering (75) to learn and craft them, and all armor type patterns are available from the trainer.
Gather Required Ore and Reagents
You will need at minimum 60 Obsidium Ore, 420 Elementium Ore, 84 Volatile Earth, 42 Pyrite Ore, 70 Volatile Fire, 70 Volatile Air, 70 Volatile Water, and 28 additional Volatile Air, plus 
Chaos Orbs (available on the Auction House), 
Inferno Rubies (x2), 
Ocean Sapphires (x8), and 
Dream Emeralds (x4) — mine what you can and purchase any shortfall from the Auction House.
Craft Intermediate Components
You will need an Alchemist to craft 
Truegold from the ore and volatile reagents, a Miner to smelt 
Hardened Elementium Bars, and your Engineer to craft 
Handfuls of Obsidium Bolts and 
Electrified Ether.
Craft All Seven Goggles
Using your assembled components, craft all seven goggles: 
Agile Bio-Optic Killshades, Deadly Bio-Optic Killshades, Energized Bio-Optic Killshades, Lightweight Bio-Optic Killshades, Reinforced Bio-Optic Killshades, Specialized Bio-Optic Killshades, and 
Camouflage Bio-Optic Killshades — the goggles are Bind on Equip, so any you do not need can be sold on the Auction House after crafting.
Claim Your Cosmetic Rewards
Upon completing the achievement, check your in-game mail to receive the cosmetic appearances for all seven goggles — note that Classic Engineering (1) is required to use the appearances, so the cosmetics are only usable by Engineer characters.
Tips
The Profession Shopping List addon can be used via /psl to automatically calculate all required reagents for this achievement and track what you already have in your bags.
