Hey Ben, I am not familiar with the term "Mug Base" but an iron pontil is actually a pontil SCAR left by a pontil rod coated with iron to help ease the seperation from the blown bottle. This rod is what the glassblower would hold and use to turn while the lip was being applied. Applied lip is just that. there are many different variations of applied lips, but they were all done after the blowpipe was removed and the bottle was blown. It is basically a blob of glass applied to the sheared lip and then molded to one lip style or another depending on what tool was used. I believe this type of lip molding started around 1840. hope this helps. Kelley
