will these bowls stain if microwaved with tomato soup or tomato sauce?

They shouldn't, I've used them for other tomato-based soups and did not have an issue.

The product description says that they are not microwavable. Melamine is like that; it's great on all fronts by microwave makes the plastic slowly become brittle and any oil or fat in the food you are microwaving reacts in weird ways with the bowl to stain or even blister. In our house, we never microwave plastic. Nuke it in glass, transfer to plastic.

The company's own website said yes. Especially I would think in white, but in all fairness I had the other colors.

I love these bowls for personal use cause they are so user friendly. The outside stays cool with hot soup in the bowl and the non slip base is great. I got the blue ones. No staining yet but if you are getting white they might. Others have reported that their website says they will stain. My only complaint is that they scratch if you use metal utensils especially forks. In blue the scratches become very visible which is why I only use them when dining alone. In white the scratching might not be so evident because the scratched on blue bowls appear whitish. White scratches are probably less noticeable on white bowls I love these bowls for personal use cause they are so user friendly.

Place tomato stained items outside in direct sun for several hours...staining should be removed.

Yes, the bowls are microwave safe. I mostly use them for melting butter and melting coconut oil. I also use them to put small amounts of cinnamon, salt, etc., in when I am cooking. The little attached "handles" make the bowls real easy to grip. I have a cat, but have never used them to feed the cat - will try and let you know.

I used it for like 30sec in microwave and its stained the bowl, I had pureed carrots in it. So I was fairly disappointed.

Peter, First off, I don't microwave in plastic containers, so I can't answer that one. However, I haven't had problems with staining from storage of tomato-based foods. Hint: when my plastic containers have stained, I have 'bleached' out the stains by setting the containers out in the sun. Back to the Rubbermaid Easy Find ..., they are the best food storage containers I have used, especially for freezer storage. Just don't drop them when they are frozen.

These are dish washable and Microwaveable. These Cornell bowls are super great for soup and presentation with the larger bowl. Haven't used Nordic Ware dishwear only pots and pans.

I've microwaved them without issue. The enamel hasn't been damaged at all. Be careful grabbing the handle though since it does heat up.

I have not microwaved the pots. The pots have a metal lining (stainless steel?) in the inside. I don't think it the pots are microwave safe.

Yes we have seen stains. Ours have come mostly from cooking potatoes with their skins on. I haven't done a lot of carrots or tomatoes in them. We have done chili but I don't think that stained as much as the potatoes.

They are dishwasher safe and, unlike melamine, they do not heat up in the microwave (instead of the food). Elsewhere, a reviewer complained about staining, but I did not experience that.

A little bit, I always use pot holders to remove food reheated in the microwave. We love these bowls to serve all kinds of food, but I don't use them in the microwave too much. They are a great size and we love the colors.

They are very microwave friendly. We use them daily for soup and cereals and anything edible. They're great bowls.

I have never used them in the microwave. Sorry I can't answer your question. I can tell you that I love the bowls, though!!!

I have to echo Bob, staining what? should never feed food in anything other than ceramic or stainless steel, safer for the pets. I've not ever had probs. with this food staining my stainless bowls though,,,

No, I haven't had any trouble with the plastic staining. I put crushed tomatoes for spaghetti sauce through the mill, and the tomato comes right off when I wash it. The first time I did that I thought it might stain, but it didn't.

I haven't used mine in the Microwave since it says on the bottom of the bowl not to. I don't always follow instructions, but I sure don't want to mess these nice bowls up!!

They are NOT indicated as "microwave safe" on the bowls. They are a Type 2 plastic, which is "high density polyethylene" (HDPE) = May be safe, although some recommend against food contact when microwaving. I personally do NOT use these in the microwave. They seem fine in the top rack of the dishwasher, but I wouldn't put them on the bottom rack.
