Glass, Safe to boil or not?

KatPawz2003 KatPawz2003
I have heard different things on the safety of using boiling as a way of cleaning glass. I personally use soap and water as I am the only one using it, but I am potentially going to be getting some glass for strap on use.

Some people say that it is safe and one of the best ways to clean it, while others (I don't remember who) have stated that it is not safe as it can cause the glass to break. I know that the glass used is Borosilicate Glass, A.K.A. Pyrex, which is oven and dishwasher safe. Pyrex dishes say not to use on the stove top, but I believe that this is due to uneven temperatures through the dish as it heats.

Any advice, opinions, or bad experiences are welcome here.

Most glass toys should be perfectly safe to boil. Particularly borosilicate glass.

The only things you want to watch for are uneven heating (just like Pyrex) and avoiding sudden temperature shifts (ie. don't go from boiling to ice water).

As a sidenote, be gentle with glass as a strapon dildo, it's way less flexible/forgiving to the receiver than silicone or similar materials. It's still a great material though and can be used, just carefully.

Actually, Pyrex (borosilicate glass) is meant to go from oven to freezer but I'd still avoid very sudden temperature shifts. I never recommend microwaving glass because of the uneven heating...hot spots can cause pretty painful burns. I see absolutely no reason to boil glass though...a good washing in hot water with some soap is all you really need!

I am careful when using glass in general for this reason. Both myself and the other person are experienced in using glass.

My main concern is that one of us is more prone to yeast infections and the other gets UTI's every 4 or 5 months. I don't want to run the risk of potentially causing either problem for the either person if we decide to change up who wears it for the next time we use it.

I've never boiled a glass toy, but I've read that it's best to put the toy in the water when you begin heating it so the temperature can change gradually. Can anyone confirm or deny this?

I think it's a good idea. Especially if the glass is thick, internal stresses can develop from the temperature change, which could cause a crack.

I would not recommend freezer to oven, or any sudden temperature changes. Pyrex cookware is much thinner than a glass dildo, and the hot air of an oven transmits heat slower than liquids. Even though it might be a 400-degree oven, as you probably know from sticking your hand in to retrieve something, the air of an oven doesn't burn you very fast. However, put a 400-degree piece of glass in some ice or a puddle of water, and I would bet it cracks.

Glass dildos are also much thicker than cookware, so internal stresses could develop between inside and outside, leading to a crack. It's unlikely to happen at the low temperatures of boiling water, but you also never know if there is already a defect inside the glass that makes it more susceptible.

Another caution when boiling glass: wrap the glass in a dishtowel then place it into the water. This will cushion it from bouncing around in the pot, and will also provide a little insulation from the bottom of the pot, which may be hotter than boiling.

That's a great tip with the towel. Thank you for answering!

What other materials besides a dish towel would you suggest? I like the dish towel idea, but would love to have some other options in case they are in the wash.

I would be more concerned about the glass toy clanking around in the pot. While the temperature change shouldn't matter, I feel that there are safer options for cleaning your glass toys. I wouldn't boil them, but I'm extra safe with my pieces.
