Is air drying or oven fired clay suitable for making ceramic shot glasses?
Sorry, You need clay and glaze that is fired in a ceramic kiln. You could look into some ceramic classes next year. For this year. you can get some glass shot glasses and paint them There is a paint that can be purchased at some craft stores that becomes top rack dishwasher safe after it is baked in an oven Apply the paint only to the out side that will not contact the drink.
