DMC Field Trip
Hosted by the Alabama Mineral & Lapidary Society
Iron Related Tours and Hike
Saturday, February 29, 2020

A few zigs and zags because of last minute changes didn't keep the AMLS from hosting a great trip. It included a tour of Sloss Furnaces and a hike in Red Mountain Park. There was also an iron bowl workshop the night before the trip.

Iron Bowl Workshop
The night before the trip, field trip attendees were invited to participate in an iron bowl workshop at the Metal Arts area of Sloss Furnaces. Before we started working on our bowls, we learned how the mini blast furnace worked and we learned about the materials used in it to produce the iron for our bowls. Then we used metal tools to etch designs into inner and outer forms made of sand held together by a urethane polymer. The two forms were put together to form the bowl mold, then metal artists poured molten iron into them. As the iron cooled and the molds were removed, everyone waited eagerly to see their bowl appear. After the bowls were revealed, we watched as the metal artists emptied the furnace and cooled it down for the next iron pour adventure.

Sloss Furnaces Tour
The trip started at Sloss Furnaces. AMLS member and temporary trip leader Sandra Sullivan welcomed everyone and showed us samples of iron-related rocks. Our tour guide, Ty, explained how the abundance and quality of natural resources in and around Birmingham were perfect for producing iron. As we walked through the site, he told us how iron ore was processed and how the process changed from the time the furnaces were fired up in 1882 through the time the last iron flowed there in 1971. He also told us about the human side of Sloss. The relentless heat of the furnaces, the inherent dangers of working around molten metal, and iniquities among the workers made it a difficult place for the people who worked there. Ty gave us a special tour that not many people get to experience. He even gave us some special gifts!

Red Mountain Park Tour
After the Sloss tour, we regrouped at Red Mountain Park. Our guide Jeff, led us on a tour of a fraction of the 1,500 acres encompassed by the non-profit park. A staggering amount of iron ore was mined in Alabama. Various sources estimate as much as 700 million tons of iron ore were mined in Alabama from the mid-1850's through the 1970's, mostly from the Birmingham area. Jeff showed us various buildings and mining artifacts, explaining what they were for and how they were used. He also took us to some of the mines where the ore was extracted. He talked about how there were different types of ore there, one better than the other, and showed us examples of both. The human aspect of iron ore mining also came to life as Jeff told us about the people who mined the area as well as the people who ran the mining companies.

Lasting Impressions
As I write this report, I realize the experience was a satisfyingly odd way to learn about something -- from end to beginning -- making a bowl out of iron that came from a place like Sloss Furnaces that processed iron ore mined from a place like Red Mountain. By experiencing everything in reverse, each step along the journey added to the prior in a way that peeled back layer by layer the various aspects of iron in Birmingham.

Many Thanks!
There were so many people who made this trip successful. Sandra was a trooper, working hard to recover from a firestorm of last minute difficulties to honor her club's DMC hosting commitment. She brought several examples of local materials related to iron processing for attendees to see, and she told many stories of her family's personal history with Sloss Furnaces.

Marshall and all of the other metal arts artists gave us an unforgettable iron pour experience at the bowl workshop. They welcomed us into their world of metal arts, helped us etch our designs, tamed the dragon that oozed iron for our bowls, and taught us how cool hot iron can be.

Ty was so gracious and generous scheduling a last minute tour of Sloss Furnaces for our group. Our tour was filled with his impressive knowledge and enthusiasm for the history of Sloss, Birmingham, and the people who made that history. He went above and beyond for us and we sincerely appreciate all of his efforts.

Erika at Red Mountain Park worked diligently to help set up a last minute hike for us. Jeff led that hike with a passion for the history of the park that made our journey into the iron ore mining history as fun as it was educational. He (and his wife) capped off our fantastic trip and we thank them for our tour as well as everything they are doing for the park.

Ty and Jeff even managed to entertain the youngest members of our group, truly an accomplishment itself!

Many thanks to everyone who made this trip so enjoyable, including club members from all over the southeast who came together for this wonderful trip!
