I wanted to encapsulate objects into glass bowls with the resin. Since heat is produced during the curing process, is it safe to use in glass?

It does not get much warmer than setting plaster, it should be no problem in glass.

I would assume that you could but the heat might cause the glue holding it in place to melt (0-0) although that already happens eventually....

The description says they are made from borosilicate glass, which is the same as Pyrex. They should handle heat just fine.

The correct method is to chemically etch the glass, not paint it. You should be looking for glass etching kits, not paint.Official warning from Rust-Oleum: "model # 182510 isn't meant for heated surfaces." - Referring to their frosted glass spray.

I don't believe the plastic insulation could sustain that kind of heat. The insulation is very similar to bubble wrap used in shipping packages. Even if you were fortunate enough to not have smoke and a fire from using it with so much heat, I suspect it would quickly melt the plastic and lose most of it's insulation value. Just my opinion. I only use it on conventional heating ducts.

I have baked with the various sizes of Pyrex rectangular ware (and circular pie plates) for a long time at high and low temperatures. I don't use the plastic lids or aluminum foil because they both outgas into the food and make me ill. If a lid is needed, I use Corning Ware with glass lids. I wonder if your question is written incorrectly. I don't understand why there would be a question about baking for long periods at a temperature under 400F, but I can understand why someone might wonder if the Pyrex can be used for long baking periods at temperatures over 400F.

Don't ever do that. The top neither the glass is heat resistant. Unless you want to ruin your investment.

It doesn't do well when heated. So if you're process includes heating then I would be careful.

I wouldn't. The glass isn't made for that. It's for putting on a hot plate with that'll only get so hot, not an open flame. It'll shatter.

the borosilicate glass itself is freezer safe but there is a thermal barrier between the layers with an unknown sealant so I would not risk it

Must be put in a cool dry place. Make sure exact equal parts are mixed it's important or it won't harden. If mix properly it is usually 24 hours. I put my creations on a tray with a paper towel (you don't want to get this resin on anything it will ruin it) and place in my micro wave over night, just remember not to turn it on. The reason why is if you have animals or children or anything falls on the resin or touches it you won't get a perfect product.

i would not. it's made out of glass, maybe high heat resistant glass similar to pyrex, but i wouldn't bet on it.

This glaze is safe over most things. As long as it doesn't rub off when you touch the item then you should still be fine to glaze it.

I'm not certain. I do know that it wasn't heat resistant. When I poured hot mix into the mold it changed shape. This could have been my mistake certainly. I only tried them once.

The jar is not totally made of glass. I bought the kettle after reading these answers and wondered how the glass jar is attached to the stainless steel heating element. There is some kind of plastic (maybe silicone?) part that holds that glass jar and the heating element together and also acts as a sealant. I opened the lid after emptying the hot water (while the pot was still hot) and got a whiff of a very strong plastic odor. I'm pretty certain that the plastic part is being heated to high temperatures. My pot is going back.

This wouldn't really be a good choice for gluing glass. I personally would use epoxy or super glue. The latter would be the easiest.

Mine have held up fine through many re-heats (although mine are different than this picture, the lids are hard plastic with a rubber gasket and snap on). The glass bowl certainly is microwave safe, so if you are extra-conscious about plastic in the microwave, just take the lid off.
