Use instead of plastic or paper towels to cover plates in the microwave to keep the heat and moisture in, and to keep food from splattering. Use it to cover a pan on the stove so you can monitor what’s cooking. It's also safe for use in the oven. Non-porous glassware, won't warp or discolor.

Love it!

Love it!

Ordering my third. We used the first for several years before we broke it (totally our fault) and are still using the second (going on second or third year now). This third one is for our lake house. Love not having plastic!

Great Alternative to Plastic

Great Alternative to Plastic

We bought this to reduce the amount of plastic wrap we were using (and microwaving). Today my husband dropped it when transferring something covered to the fridge (marinating chicken) and broke it so we are getting a new one. I will say I have dropped it before but it never cracked, and we've had it for two years. It is glass so I expected it to break with a certain amount of misuse and was surprised it didn't break sooner. We really like the functionality, cleans up easily and stores on top the microwave.

Not so great

Not so great

Love the idea of it but bumped on the microwave and broke in lots of pieces. Ugh... it was a light bump. Bought it in September and it broke in November.

Could Be Sturdier

Could Be Sturdier

I was thrilled to find this as a replacement to the plastic cover we were using. We are very careful with it and my husband and are the only ones who use it (i.e., not the kids). However, we were very disappointed to see that without any known dropping or bumping it, it cracked to where it can no longer be used. We have had it for about 1 year and a 1/2. I think it should last longer than that. Mighty Nest doesn't guarantee it after 90 days. That is disappointing and now we need to decide if we should buy another one or try to find something else.

I purchased the microwave cover at the end of October. Today (end of January), there is a chip out of the edge and a crack beginning to go up the side. I was very excited to find this product but it definitely did not live up to my expectations.

Catamount Glassware was founded in the late 1970's by Alain Karyo, an artist and student of modern architecture. His designs combine form and function, two essential elements in creating practical, easily handled cookware. Made from borosilicate glass, the Catamount products were originally developed for use in scientific laboratories. These crystal clear Catamount products are flame, oven, microwave, and dishwasher safe. All of the Catamount glass is assembled and printed in the USA. Borosilicate is one of the purest forms of glass. No heavy metal. The inks are heavy metal free and we are in the process of changing to organic inks.
