Glaze is made of powdered silica and alumina and chemicals to make it melt at the right temperature. It is usally mixed with water to apply it to the pot. When it is heated to the right tempurature the glaze turns to liquid glass. If it is on the bottom of the pot then when it cools it will be permanently stuck to the kiln shelf it is sitting on. Some pots were fired on their rims insteand and the rims were covered with metal. Other pots are fired on stilts that touch the bottom of the pot in three points. In that case the bottom can be glazed and the stilt broken off. Some wood fired pots and salt glazed pots are put on wadding (small balls of high alumina clay) to keep them from sticking. Sometimes they still have to be ground clean of glaze. Other glazes like crystalline ones always run and must be put on high stilts and always ground clean in order to sit flat.

It is not a matter of superiority. It is a matter of difference. The glazed pottery is better for cooking and for ornament purposed for having smooth surfaces that would keep the pottery more easily away from contamination.

Is Frankoma pottery safe to eat on?
Frankoma pottery is known for its distinctive designs and craftsmanship. It was a popular American pottery brand that operated for many decades. Frankoma pottery is typically made from clay and is glazed to create a smooth, finished surface. However, whether or not it is safe to eat off of Frankoma pottery depends on various factors: **Glazes:** If the pottery is glazed, it's important to know whether the glaze used is food-safe. Most modern pottery intended for use with food is made with food-safe glazes, but older pieces may not adhere to the same standards. Lead-based glazes, once common in older pottery, can be a concern as lead is toxic. **Condition:** The condition of the pottery is also important. If there are cracks or chips, bacteria can accumulate in these areas, making it unsafe for use with food. **Intended Use:** Some pottery is purely decorative and not intended for food use. Check for any markings or information on the bottom of the piece that might indicate its intended use. **Manufacturing Date:** If you know the manufacturing date of the Frankoma pottery in question, you may be able to determine whether it was produced during a period when certain materials or glazes were used that may not be considered safe today. To determine the safety of using Frankoma pottery for eating, you may want to consult with a pottery expert, contact the manufacturer (if still in business), or conduct research on the specific piece and its production era. If in doubt, it's generally safer to use pottery that is explicitly labeled as food-safe or to use vintage pieces for decorative purposes only.
