A mug decorated with glass painting materials and intended for use for its intended purpose, i.e. for drinking both hot and cold drinks.
The mug can be safely washed with cold and hot water with soda and other mild detergents.
The stability of paints has been proven by long experience of use.
The pattern is resistant to moisture and other external influences.
How to keep
I recommend not washing in the dishwasher, despite the fact that the paint is resistant and can withstand such washing, but it is better to avoid it.
It is advisable not to use abrasive materials when washing.
