Porcelain dishes - dishwasher safe?
I just impulse bought some Linnea Arabia bowls made in Finland from an antique store. From searching online, it appears these are porcelain and it definitely looks Iike it has a glaze on it. Any ideas whether these are dishwasher safe? I'd hate to ruin the glaze or something - my dishwasher does get crazy hot.
If they date from the fifties or before, they probably aren't dishwasher safe. From the sixites and seventies, possibly. From the eighties on, probably.
The earlier china or porcelain said plainly "dishwasher safe" on the bottom of the piece. Usually.
I think you could write to the company and ask. Perhaps you could ferret out an email address, and send along a photo of the piece, incl. the marks on the bottom. Good luck!
If you are concerned enough to ask the question, I would hand wash them. The dishwasher detergents are so harsh that eventually it will have some sort of detrimental effect on them.
I had Arabia in the late 60's. It always went into the dishwasher. It is porcelain and is just fine. The only "ceramic" product I would not but in my DW is antique hand painted items. I even put bone china in my DW. I don't use the heated drying setting and do not touch it until it is at room temperature. Many of the china companies recommend using the dishwasher. It is safer than slippery wet hands.
