This is from Jeff Rudolph:
… some shots from Fox Lake … On April 8th, 2013, Fox Lake Fire Department responded to a fire in the 38,000 block of Hillandale in unincorporated Spring Grove. Engine 223 was first on scene and found an elevated one-story home fully involved. The incident commander quickly called for additional resources, including an Antioch engine and a Spring Grove tender. A second alarm was pulled, bringing in more tenders and chiefs, as well as special units from McHenry and Newport.
The terrain proved challenging—steep and rugged, with narrow gravel roads that made access difficult for both firefighters and equipment. At first, it was feared that someone might still be inside the burning home, but the resident returned from the store just in time to see crews working to save his property. Firefighters worked late into the night, extinguishing the flames and conducting a full overhaul of the structure. Fortunately, no injuries were reported.
Jeff Rudolph captured several powerful images from the scene, showing the intensity of the fire and the efforts of the responding crews.

### 1. **Classification by Filler Metal Composition:**
- **Pure Iron-Based Brazing Alloys:**
These alloys consist primarily of iron, with small amounts of other elements added for specific properties such as improved flow, wetting, or corrosion resistance.
- **Iron-Nickel (Fe-Ni) Alloys:**
These alloys contain significant amounts of nickel, which enhances the alloy's strength, ductility, and resistance to corrosion. They are often used in high-temperature applications.
- **Iron-Chromium (Fe-Cr) Alloys:**
Chromium is added to improve the oxidation resistance and hardness of the brazed joint. These alloys are suitable for applications requiring high wear resistance.
- **Iron-Manganese (Fe-Mn) Alloys:**
Manganese is added to increase the strength and toughness of the brazed joint. These alloys are often used in structural applications.
- **Iron-Silicon (Fe-Si) Alloys:**
Silicon is added to improve the fluidity and wetting of the filler metal. These alloys are commonly used in electrical and electronic applications due to their good electrical conductivity.
### 2. **Classification by Brazing Temperature:**
- **Low-Temperature Iron Base Brazing:**
This involves brazing at temperatures below 900°C (1652°F). It is suitable for joining materials that have lower melting points or are sensitive to high temperatures.
- **High-Temperature Iron Base Brazing:**
This involves brazing at temperatures above 900°C (1652°F). It is used for joining materials that can withstand higher temperatures and require stronger joints.

Iron base brazing is a category of brazing processes that use filler metals with iron as the primary element. This type of brazing is widely used in various industrial applications, particularly where high strength and good corrosion resistance are required. Below is a classification and brief introduction to iron base brazing:
