White Silicone Rubber Sheet, 60A Duro, 1/16 x 9 x 12 Inch, Food Grade, Made in the USA, No Adhesive Backing, High Temp Heavy Duty for Gaskets DIY Food Covers Lids Sealing Material Pads Oven Protection

Very high quality silicon. It’s difficult to find white as most on the market is “opaque” or translucent meaning you can faintly see through it. These sheets are pure white and come as advertised. I especially appreciated the small card inside that showed they really cared for me as a person. Would definitely purchase product again. :)

Made a gasket for a very large jar. Works well so far.

good item

I bake sourdough regularly, and so many times I ended up with an overdone bottom. I decided to get something to try to insulate the loaf from the bottom in the 480° oven, so I took one of these and cut a circle slightly greater diameter than the flat part of the bottom of my 6-qt. Dutch oven. I needed the extra thickness compared to a lot of silicone sheets. Since this is only 1/16" I got two in case one wasn't enough. One has been ok, but I think I will be cutting the second circle soon, and maybe even try to find something heat-resistant to put in between the layers. It definitely has helped with the doneness. The only "problem" I have is that the several loaves I've done using it have stained it, but it doesn't matter what it looks like. It works pretty well, and I believe adding a second layer will be even better.

I needed a new gasket for my cookie jar as the old one had hardened over time and was no longer protecting the contents from moisture. The exact exterior and interior ring size was impossible to find and the rings I found that might work were pricey. I found this silicone sheet to be the perfect fix. I was able to cut out the circular gasket I needed to my exact specifications.

I cut it to make some seals. It worked great.

Perfect

Even after washing this product, it still leaves a white residue on the counter top. I'm afraid to use it with food.
