Can I use polymer clay to decorate food-serving pieces?
Residual plasticizer can remain in the clay after firing, and this plasticizer might leach out into food that touches even the fired clay, so it may not be safe to use polymer clay on surfaces that will be in contact with food. This shouldn’t be a problem for pieces that don’t touch food directly, such as napkin rings. If you want to use polymer clay for a serving dish, consider sandwiching your clay design between two pieces of glass – that way it can be seen without touching the food on the dish.
