"Rubbermaid Glass with Easy Find Lids™ is manufactured from soda lime tempered glass.
- Soda lime tempered glass is a lighter weight alternative to borosilicate glass that offers the ability to manufacture with thinner walls, which in the case of Rubbermaid Glass Food Storage, enables Easy Find Lids™ functionality and improved aesthetics.
- Soda lime tempered glass is safe for kitchen use and is significantly more resistant to breaking on impact than borosilicate glass and is able to withstand temperature changes appropriate for its intended use.
- Soda lime tempered glass is processed by heating above its annealing point and then cooling rapidly– achieving thermal shock resistance.
- Both soda lime and borosilicate bakeware can experience thermal breakage if exposed to sudden or uneven temperature changes. To avoid breakage from thermal shock, ALWAYS use as directed in the product use & care instructions."

"The Rubbermaid Glass Use & Care states that glassware should always be placed in a preheated oven. This is because:
- If the oven is not pre-heated, glass could be exposed to uneven sources of heat, which could cause breakage.
- Ovens heat up at different temperatures and speeds, and preheating allows you to have a uniform temperature to start at."

"Yes, Rubbermaid Glass with Easy Find Lids™ are safe for use in conventional microwaves.
- Use minimum cooking time to heat oil or butter.
- Do not use product to microwave popcorn or heat foods wrapped in a heat-concentrating material.
- Plastic lids are made of microwave safe materials that can be used to reheat foods to a temperature comfortable for eating.
- Lids are not intended for cooking or for use in a conventional oven.
- Lift corner of lid to allow steam to vent when microwaving. Sealing plastic lid while heating may create extra pressure causing lid to melt, warp, or creating excessive steam build up.
- Always open container away from body to prevent burns."

"Yes, Rubbermaid Glass is safe for freezer use.  Do not take container directly from the freezer to the oven.  "

"Rubbermaid Glass is dishwasher safe.  Rubbermaid Glass lids are top-rack dishwasher safe. Be sure that the lid is secured so that it does not come in contact with the dishwasher element to avoid melting.
 
When washing by hand use non-abrasive cleansers.  If more vigorous cleaning is necessary, soak and clean with non-scratch plastic or nylon scouring pad.
 
Separate leak prevention gasket from lid for cleaning and replace for use. The leak preventing gasket is also top-rack dishwasher safe. "

"With Rubbermaid Glass, you'll never lose your lid again since Easy Find lids snap to the bottom of the container and to each other. Cabinets stay neat and organized because the graduated container sizes stack neatly inside each other taking up less space in your cabinet."

Thank you for your interest in Rubbermaid, and for taking the time to contact us regarding the repair of your product.

Most of our products are made from polyethylene and polypropylene. One of the features of these plastics is that they are easy to clean because materials do not adhere well to them. Unfortunately, this property prevents adhesives or paints from sticking well. We know of no way to change this fundamental property of the plastic at the point of use.

It is usually easiest to start the gasket in a corner of the lid and snapping it in place. Once you have the corner started, you can run your thumbs along the gasket to seal it into the lid.

Please see photo of lid and gasket that is attached.
