Old Fireplace Mysteries. I am going to explain this as simply as I can. #misc

- They had a large metal backplate to reflect infrared rays when the fireplace heats up.
- The andirons, the objects to hold wood, had no arms to hold wood.
- The furniture does not appear to cluster around the fireplace like usual, implying a greater heating range.
- Many of the fireplaces are very large, even the opening, which is not ideal for ventilation when smoke is involved.
