When we were in grade school we had to learn about ionic, doric, and Corinthian columns. We also had to learn what convex and concave mean. Do you remember? I will save a lesson on Greek columns for another day. Today, let’s turn our attention to “convex” and “concave.”
Concave—having an outline or surface that curves inward. I tried to remember it this way: I think of a collapse or a “cave in.” That brings to mind “concave” or curving inward.
Convex—having an outline or surface that curves outward.
The style of the day when American colonists were decorating their homes was to hang a Federal convex mirror with a frame made from wood. An American eagle often was on the top.
Maybe you have seen a convex mirror in an alley way or some other “tight” space.
I bought one at a garage sale last summer for $1.00. The frame is made from wood and another compound, possibly gesso. I used it on the back wall of a cabinet. It brings more light onto the shelf.
Some people like the look of the mirror, but not the eagle on the top. The form can be reduced down to just a round frame and it may be painted most any color. The beauty of the mirror is that it reflects items in almost the whole room, not just what is in front of it. It bounces light back into a room and really adds sparkle. Here are some beautiful ones. Some frames are more ornate than others.
