Sodium hydroxide, a highly caustic base and alkali, is known by several other names that reflect its chemical properties and uses. One of the most common alternative names is "caustic soda," highlighting its corrosive nature. It is also called "lye" in many contexts, especially when referring to its use in soapmaking or drain cleaning. In industrial circles, it might be referred to by its chemical formula, NaOH. Additionally, its historical name, "soda lye," links it to its application in soap and glass manufacturing. These varied names emphasize its wide range of applications, from manufacturing to cleaning products, underlining the importance of sodium hydroxide in both industrial and domestic spheres.
Yes, white zircon can be cloudy due to the inclusion of microscopic minerals within the gemstone or if it has been heat-treated inadequately. White zircon, a natural gemstone valued for its brilliance and fire, can have variations in clarity. While high-quality white zircon is typically clear and transparent, resembling a diamond, lower quality stones may appear milky or cloudy due to these inclusions or suboptimal treatment processes. When selecting white zircon, it’s crucial to examine the gemstone for cloudiness, as this affects its aesthetic appeal and value. For those seeking the clear sparkle, selecting a higher-grade stone, possibly with the help of a gemologist, is advisable.

It is true that white zircon can sometimes become cloudy due to inclusions or internal defects. However. high quality white zirconia should be naturally clear and lustrous.
When referring to a "20 polypropylene blue filter," it generally indicates a water filtration component made from polypropylene, a durable plastic material resistant to chemicals and temperatures. These filters are popular in various water filtration systems, both residential and commercial, due to their efficiency in removing particulates, dust, and sediment from water. The "20" typically refers to the length of the filter, which is 20 inches. The diameter can vary but is commonly 2.5 inches for standard housings or 4.5 inches for larger (big blue) housings. The micron rating, determining the size of particles it can filter, can vary depending on specific needs, ranging typically from 1 to 50 microns. It’s important to select a filter with the appropriate micron rating and size for your specific filtration system to ensure optimal performance.
