Borosilicate glass/quartz safe?

[envyxoa]

I have a concept for a dry herb vaporizer using direct inhale similar to sticky brick but im unsure the safety of borosilicate glass or quartz when its being heated and transfered directly to the flower am I overthinking or how do they make them?

Are you asking if quartz is safe to heat in a vape? Boro cracks at a lower temperature than quartz but it is still resistant to 500F. Quartz is resistant to like 1500-2000F. That's why we use it for glass nails, etc.

Im asking if borosilicate and or quartz is safe to inhale when heated inside through a direct inhale device. I read it releases chemicals you dont wanna inhale and when you at least arent inhaling directly through it. Its going to your flower.

I can't imagine a substance that I would be less worried about honestly.

Definitely you should avoid it if you don't feel like it's safe. But I am going to keep using my bangers and vintage Pyrex.

If boro or quartz aren't safe enough, then I don't know what is. As is, a lot of people don't want metal options for that reason. Unless ceramic is safer (I have no idea), I can't imagine what other material could even withstand the heat, let alone be safer.

In other words, if those aren't safe, then I guess switch to edibles, tinctures, and RSO, though I doubt any of those are made with out heating up the material in glass or metal to decarb them.

A respiratory therapist I knew used to say, "Breathing in anything other than good quality air is not likely to be as healthy as that air."

If you're asking specifically about what could potentially be unsafe about a brick type design, it's the butane from the torch safety that people tend to be concerned about, not the glass or quartz used for the intake...

Yeah glass is inert as it gets. Just clean it?

well. I read that borosilicate glass when heated releases tiny particles that cause issues when inhaled but. considering that's the glass used even for combustion and no safety issues with the actual glass have happened or seem to have then I was just overthinking.

i use borosilicate glassware for my vape and absolutely love it. however, @envyxoa question brought back memories of a discussion about spallation. so i asked copilot:

explain for borosilicate glass. can thermal cycling up to 450°F cause spallation?

Borosilicate glass is known for its low coefficient of thermal expansion, which makes it highly resistant to thermal shock compared to other types of glass. This means it can withstand significant temperature changes without cracking or breaking.

Thermal Cycling and Spallation​

Thermal cycling refers to the process of repeatedly heating and cooling a material. For borosilicate glass, thermal cycling up to 450°F (232°C) is generally within its safe operating range. Borosilicate glass can typically withstand temperature differentials of about 300°F (165°C) without fracturing.

Spallation Risk​

Spallation, the process where material is ejected from a larger body due to stress or impact, is unlikely to occur in borosilicate glass under thermal cycling up to 450°F. The material's resistance to thermal shock means it can handle these temperature changes without significant risk of spallation.
However, it's important to ensure that the glass is not subjected to rapid and extreme temperature changes beyond its tolerance limits, as this could potentially cause damage.

tysm this is exactly the answer I was looking for much appreciated.

just to put the topic of spallation to bed ... i've been trying to remember why this term was stuck in my head.

and i remembered that several years ago (original thread may 17, 2010 - search spallation) i chanced upon a medical article about spallation in tubing used for dialysis and i thought about tubing used for some vaporizers.
