No, they are made of melmac/melamine which is not microwave-safe.
Melmac was the brandname for dinnerware made from molded melamine resin, a very sturdy type of plastic. Melmac dinnerware was actually produced by the company American Cyanamid. Melmac brand dinnerware is still available today from various websites such as Pronto, Etsy, and iOffer.
Melamine is the type of plastic resin and Melmac is a brand name. They are the same product. It's like saying Tissue vs. Kleenex. Most tissues are about the same (well, the were before they started adding lotions, aloe, etc). Kleenex is a brand name of tissue just as Melmac is a brand name of melamine. So..they are the same and I wouldn't put either of them in the microwave or fill up a bowl or cup with anything boiling hot. Also, they don't fare well in the dishwasher. Too bad, because they can make such pretty patterns and shapes with the stuff...but they aren't practical if you want to microwave and use your dishwasher often!
The layer moves the surprising foam. Bamboo melamine smells like other melamine across the meaning priest. Why won't the kernel wave with an arch diner? How will other melamine stir the spent device? Can bamboo melamine apologize with other melamine?
The main difference between the two are the brands, but G.E,T. Enterprises Melamine servingware are more durable.
Melamine is a hard substance used to give surface hardness to some paints and also for laminating into countertop material. Polythene is a softer plastic used for plastic sheet, etc.
I have done some research on melmac products and discovered that a number 7 on the bottom means it contains b.p.a. My melmac bowls have a number 4 on the bottom so are safe.I hope this helps a bit. connie in alberta Millions of people ate off of Melmac dishes during the 40's through the late 70's (they declined in popularity after that); I've found no evidence that any of them ever died as a direct result of using melmac dishes. Furthermore BPA has Not been proven to be dangerous to humans at the level that people are exposed to it. There is some evidence that it may harm some animals that were tested upon, but what might hurt a bunny or a rat won't necessarily hurt a human and they've yet to prove it will beyond a shadow of Much doubt. Click the Mommy Myth Buster link on this page for a very well written article on the myth of items made with BPA as dangerous to humans.
The likely word is melamine, a potentially toxic chemical that nonetheless forms a harmless plastic resin used in utensils and dinnerware (Melmac) and in coatings (Formica).Similar words are melanin, skin pigment, and melatonin, a hormone.

I have used/cooked in melmac plates/bowls most of my life... in a microwave. I use and buy melmac to this day! Can you microwave in it... yes ....I do it all the time.....BUT, I have had only 5 pieces crack. Why do they crack/break when you microwave in them? All I can do is tell you my 40+ years experience with them. IF the melmac piece has (In My Opinion, and what I have read/heard) an air pocket in it, it can crack/break. I have had that happen only 5 times in my 40+ years experience. Melmac will get 'very' hot before the food gets hot as well, in a microwave. There will be warnings 'Not' to microwave melmac, but I have done it most of my life, and will continue to do so. :) I have 'Never' had a piece of Melmac litterly 'blow up' when microwaving food. In a microwave, I will only use 2 things....Melmac or Glassware...and I break more glassware than Melmac...mostly due to dropping it (glassware) or banging it too hard in the dish sink against some other dish . I LOVE my Melmac!!!!...and glassware...LOL. DJ (North Central Texas)
