The European manufacturer of Pyrex, Arc International, uses borosilicate glass in its Pyrex glass kitchen products; however, the U.S. manufacturer of Pyrex kitchenware uses tempered soda-lime glass. Thus Pyrex can refer to either soda-lime glass or borosilicate glass when discussing kitchen glassware, while Pyrex, Bomex, Duran, TGI and Simax all refer to borosilicate glass when discussing laboratory glassware.
Though more difficult to make than traditional glass due to the high melting temperature required (Corning conducted a major revamp of their operations to make it), it is economical to produce. Its superior durability, chemical and heat resistance finds excellent use in chemical laboratory equipment, cookware, lighting and, in certain cases, windows.
While more resistant to thermal shock than other types of glass, borosilicate glass can still crack or shatter when subject to rapid or uneven temperature variations. When broken, borosilicate glass tends to crack into large pieces rather than shattering (it will snap rather than splinter).
but still ... the boron they used for [example] NASA or other space-based-technology is of a different quality then the boron-silicate (boron + silica) compounds used in normal average kitchenware.
And yes some things manufactured in China are of poor quality .... but then again they are of poor quality and huge mass-production also from other countries as well.
Instead of pinpointing at the [sometimes] exploding cheap boron-silicate compound products,
it is more interesting to look at other qualities and things of this element.The thing that interested me most was that it was FOUND as VEINS in SALT-DOME CAPS !!!! and as veins in limestone.It appears in several spots of importance discussed in this thread
: Kara-sea area, China Liaoning Peninsula, Tibet, Kazakhstan, south America ...
So it is obviously interconnected with the salt-domes
and even local mineralized spring waters
Cosmic ray's are involved,
hydrothermal systems are involved,
clays, ...The thing that could be in play with the salt-domes is :
- radiation shielding
-> from inside out & from outside in ?- it's absorbent role in radioactive situations [human & natural],
-> remember me asking if the salt was acting as a SHIELD to protect the above from the radioactivity below / or the below from the radiation comming from above [like in radioactivity or gamma rays or other radiation rays]
Does this means that salt-domes are very very "clean" places ??? - it's a neutron-capturing substance,
-> here again : neutrons from inside going up / or neutrons from the outside trying to come in ...
ask yourself why it would be important for Nature to have an element like Boron capturing these neutrons in the CAPS of SALTDOMES ???
You know that everything in Nature has a purpose !- the work involving malignant cells and energies
-> in human bodies and thus also in the Earth herself ... its a cleaning element ! Restoration ?- resistance to thermal shock
-> thus as there was an event of thermal shock coming from outside the Earth, coming from space .. boron would resist the effects of it ... so it protects that what it makes part of [where its veins run through] ???- boron compounds play a strengthening role in the cell walls of all plants, making boron necessary in soils.
-> Thus could we say that it also strengthening for the walls of salt-domes ? or other "walls" in the soil ?
Remember that it was found out that shockwaves of EM-energy did NOT GO THROUGH the salt-dome caps, but travelled AROUND it !!! Is this because of these veins of boron leading through these salt-dome caps ?? For lifeforms :
- Boron is essential to life
- mildly antimicrobial and antibiotic
- boron compounds play a strengthening role in the cell walls
- Why are magnets with boron components the strongest type of permanent magnets ????
What could THAT tell us about the salt-domes it veins through, and the cells it reinforces ???
-> Remember that salt-domes had anomalous gravity readings ??? Gravity & MAGNETISM !!!!
What does a magnet : it pulls ...
well at the blue places on ISIS' link that showed anomalous gravity area's of the Earth, the GRAVITY WAS VERY STRONG !!! PULLING DOWN !
I think that boron has a play in THAT.These things above are the neat and important things to look at
and not the use of compounds in some cheap kitchenware.
