Blackboards are an essential tool in many classrooms, providing a surface for teachers to write notes, equations, and other information for students to see. While the use of blackboards has been largely replaced by digital whiteboards and other high-tech tools in some schools, they are still a common and effective teaching aid in many parts of the world.

As I mentioned earlier, blackboards are typically made from synthetic materials like porcelain enamel or laminate, which are more durable and easier to clean than stone. Steel is sometimes used as a base material for blackboards, but it is coated with a layer of porcelain enamel to create a smooth, non-porous writing surface.
Porcelain enamel is a type of glass that is fused onto the steel surface at high temperatures. This creates a hard, smooth surface that is resistant to scratches, stains, and other types of damage. The porcelain enamel coating also gives the blackboard its characteristic dark color, which provides a high contrast for writing with chalk or markers.
In addition to the traditional blackboard, there are also other types of writing surfaces used in classrooms, such as whiteboards, smartboards, and chalkboards. These surfaces may be made from a variety of materials, including glass, enamel, and plastic, and they may be electronic or non-electronic.
Overall, the use of blackboards and other writing surfaces in schools has evolved over time, but they remain an important part of the classroom experience for many students and teachers.
Bloomington FD in Memory of FF Christopher Brown
I just got back from the funeral for Bloomington firefighter Chris Brown, and I wanted to share some photos taken by my friend Tim Olk. It was such a moving tribute to a true hero in our community.
The procession into the service was especially powerful. Two ladder trucks formed an arch over the road as the hearse carrying Chris passed by, escorted by dozens of motorcycles. The respect shown by the fire department and law enforcement was overwhelming. You could feel the weight of loss in the air, but also the strength that comes from being surrounded by so many who loved him.
Inside, there were bagpipers playing as Chris's casket was brought in, followed by his family. His two young sons looked so brave as they walked behind the pallbearers, knowing they'd soon be saying goodbye to their dad. The service itself was heartfelt, with stories shared about Chris's life and the impact he made on everyone around him.
Afterward, as the casket was carried out, it was clear how deeply respected Chris was within the firefighting community. Hundreds of firefighters lined the street, standing shoulder to shoulder in silence, hats in hand. It was a breathtaking sight to see such a massive show of support for one man who clearly meant so much to so many people.
Tim did an incredible job capturing these moments, and I'm grateful he was there to document this difficult yet beautiful day. Chris will never be forgotten, and his legacy lives on through the countless lives he touched during his time here. Rest easy, brother.
