Question: What substance is used to make it Non Stick ?
Document: I have a small toaster oven and it is always hard to find pans than work. These are good quality and non stick! Cleans up quickly. I am very happy and would recommend these for anyone looking for a set to use in a small toaster oven.
This is a great little set of pans for those restricted to using a toaster oven. It is nice to be able to make muffins again!
Good quality and I love that there is a plastic lid for the casserole piece (disappointed that it doesn't fit over the muffin piece, though), but they were too long for my toaster oven. Make sure you measure your oven space before you purchase.
My daughter reports loving this set of toaster oven pans. They are easy to clean and fit perfectly in the much used toaster oven.
My husband doesn't like me to use the big oven in the summer, so I got a nice new toaster oven, and these dishes to go with it. So far all I've used is the smaller baking dish, which worked fine. What really drew me to this set was the muffin pan. I like muffins and am excited about being able to have them in the summer nown
I recently got a Breville "smart" toaster oven (BOV800XL) and figured this set would be perfect to use with it. It is definitely very handy! All the pieces fit in the toaster oven without any issue. They're all a nice sturdy quality so they'll last and will be great to have handy! I've used the muffin tin so far and it did what it needed to do, no problems.
I like this set, it is exactly what I was looking for. I haven't used the broiler/rack yet, so I cannot comment on that piece, but the muffin tin and baking pan are great. A previous reviewer mentioned that the plastic lid didn't fit on the muffin tin, but mine does fit (perhaps they changed the design since then?). You definitely need to measure your oven and verify the dimensions of these pans.
If you're using your toaster oven to bake for one or two, this is a great set. The photo of the product wasn't complete: it doesn't show the raised plastic lid that fits over the baking pans for storage. You can bake a small cake, pop on the lid and store. Very useful! I've used the muffin tins (buttered prior to baking) and the muffins fell out of pan onto the cooling rack beautifully. Very easy cleanup with a sponge and soapy water.
Very pleased with this Nordic Ware toaster oven cookware.
This was just the right set that I needed for my toaster oven. They are a good size and good quality. Perfect for a toaster oven at a great price.
Answer: It doesn't have a Teflon coating. It is like a lot of the Nordic Ware baking sets, it is BPA-free and melamine-free. Nordic Ware uses nonstick coatings that are water-based rather than solvent-based. Like many Nordic Ware pans, if you wash them by hand, rather than put them in the dishwasher, they stay light and are known to have even heating distribution. They clean really easily and nothing sticks to them. You might want to go the Nordic Ware site and read about how it is made. These are a champagne color so, you don't need to reduce the temperature when baking. This probably doesn't answer your question. If not, you may want to email Nordic Ware.
