Q: Pearl Ash (potassium carbonate) Usage

During the mid-18th century and into the 19th century Pearl Ash (potassium carbonate) was used as a chemical leavening agent, much the same as modern-day baking soda.
Just wondering if there is anybody out there that has used Pearl ash instead of baking soda and what kind of results you have had with it.
This is an issue that was discussed in this video, on chemical leavening:
