  1. To answer this question about Prussian blue, I need to recall its chemical composition and history.
  
  2. Breaking down the problem:
     a. What is Prussian blue?
     b. What are its main components?
     c. How is it chemically formulated?
  
  3. Chain of Thought:
     Step 1: Prussian blue is a dark blue pigment.
     Step 2: It's known as the first modern synthetic pigment.
     Step 3: The main components are iron and cyanide.
     Step 4: The chemical formula involves ferric ferrocyanide.
     Step 5: The precise formula is Fe4[Fe(CN)6]3.
  
  4. Additional considerations:
     - There might be variations in the formula depending on the specific type of Prussian blue.
     - Water molecules may be present in some forms.
  </thinking>
  
  <reflection>
  - My reasoning seems sound, based on my knowledge of chemistry and pigments.
  - I've covered the main components and the chemical formula.
  - One potential oversight could be not mentioning the different forms of Prussian blue (soluble and insoluble).
  - It might be worth exploring the historical context of its discovery.
  - Confidence level: 9/10. I'm very confident about the main components and formula, but there might be some nuances I haven't covered.
  
  Further exploration:
  - Investigate different forms of Prussian blue.
  - Look into the historical context of its discovery and use.

  1. Addressing the potential oversights:
  
  2. Chain of Thought:
     Step 1: There are two main forms of Prussian blue: soluble and insoluble.
     Step 2: The soluble form has the formula KFe[Fe(CN)6]·xH2O.
     Step 3: The insoluble form is Fe4[Fe(CN)6]3·xH2O.
     Step 4: The 'x' represents a variable number of water molecules.
     Step 5: Historically, it was discovered accidentally by Diesbach in Berlin in 1706.
  
  3. These additional points provide a more comprehensive answer to what Prussian blue is made of.

  <reflection>
  - This additional information addresses the previous oversights.
  - I've now covered both forms of Prussian blue and touched on its historical context.
  - The inclusion of water molecules in the formula provides a more accurate representation.
  - No apparent errors or inconsistencies in this additional information.
  - Confidence level: 10/10. I believe I've now provided a complete and accurate answer to what Prussian blue is made of.
  
  The user would likely say I've found the answer, as I've covered the chemical composition, different forms, and even touched on its historical discovery.

  Prussian blue is made of iron and cyanide compounds. Its main chemical formula is Fe4[Fe(CN)6]3, which represents ferric ferrocyanide. However, there are two main forms:
  
  1. Soluble Prussian blue: KFe[Fe(CN)6]·xH2O
  2. Insoluble Prussian blue: Fe4[Fe(CN)6]3·xH2O
  
  In both formulas, 'x' represents a variable number of water molecules that can be present in the structure. The key components are:
  
  - Iron (Fe) in different oxidation states
  - Cyanide groups (CN)
  - Potassium (K) in the soluble form
  - Water molecules (H2O)
  
  Prussian blue was the first modern synthetic pigment, accidentally discovered by Diesbach in Berlin in 1706. Its unique composition of iron and cyanide compounds gives it its characteristic deep blue color.
