Featured Cause of this flaw or damage?

During production? Help me understand plz.?

Not my main question but also may tips for ID’ing maker/age of unmarked Majolica?

 

Glaze skip?

 

Has a resemblance to some of the pieces taken up in this thread:

Ceramic Vase - What Did I Buy?

The bottom does not look like Brush-NcCoy to me, but a competitor. In an Internet search, Weller jardinieres appear to have more vivid color.

 

Looks like the glaze split and rolled up exposing the original pottery surface? Can that be fixed?

 

Leave it be, it's part of its history.

 

It's a flaw. American companies produced these things quickly and in bulk so collectors expect a few manufacturer defects. A perfect example will always bring more but those are few and far between in this type of jardiniere. The glaze is sometimes referred to as majolica but is really better described as a blended glaze. Most of these were produced in roughly the 1910 - 1930 era. I agree with Bronwen that the bottom does not look like Brush-McCoy. Usually that brushed on color is attributed to Weller.

 

I am used to seeing some small anomalies in the production of old Majolica for sure. This one was just something I’ve never seen. I had assumed that was about the era, glad to know I was on the money there.
