No. Decoration and glaze can have specific care restrictions. A hard-feeling surface does not establish that repeated dishwasher heat and detergent are suitable.
Understanding this situation
This is particularly relevant to handmade, antique or decorative pieces with uncertain instructions. A short programme is still a machine-washing process, and previous survival does not prove long-term suitability.
A useful next step
Use the maker's stated care or a suitable cautious alternative. Keep uncertain items out of experimental loads. If decoration changes, do not use harsher cycles to clean it away or infer that the dishwasher has necessarily overheated.
