Why glaze the inside of a pot first?

Glazing the inside of a pot first helps to prevent any unwanted drips or runs on the exterior surface when the pot is inverted for glazing. It also ensures that the interior is fully coated and sealed, which is crucial for functional ware that may hold liquids. Additionally, glazing the inside first allows for better control of the glaze application, as it can be more challenging to reach the interior surfaces after the exterior is completed.
