What is calcite?

In this video, we'll explore the fascinating world of calcite, a common mineral found in a variety of geological settings. We'll learn about the unique optical properties of calcite, including double refraction and birefringence, and discover how it forms in sedimentary and metamorphic rocks, as well as in hydrothermal veins and volcanic cavities.
We'll also take a closer look at the beautiful and intricate structures that calcite can form, including stalactites and stalagmites in caves, and explore the various industrial applications of this versatile mineral. From the production of cement and lime to its use as a filler material in plastics and rubber, calcite plays an important role in many manufacturing processes.
Join us on this journey through the world of calcite, and discover the many ways in which this fascinating mineral impacts our lives and the natural world around us. Whether you're a geology enthusiast, a curious learner, or simply fascinated by the wonders of the natural world, this video is sure to delight and inform. So sit back, relax, and let's dive into the world of calcite!

How is the light that gets split by the double refraction property of calcite traveling at different speeds when the speed of light is considered a fixed integer of 299,792,458m/s?

[@professionalgeologyclub]

When light passes through a material with double refraction property like calcite, it splits into two rays, called ordinary ray (o-ray) and extraordinary ray (e-ray), each traveling at a different speed. This phenomenon is due to the anisotropic nature of the crystal structure of calcite.
In the case of calcite, the o-ray travels at a constant speed, while the e-ray travels at different speeds depending on its direction relative to the crystal axis. However, it's important to note that the speed of light in a vacuum (approximately 299,792,458 meters per second) remains constant regardless of the medium it travels through.
So, when we say the light is traveling at different speeds within calcite, we're referring to the speed of light in that medium relative to the speed of light in a vacuum. In other words, the speed of light in calcite (or any other medium) is always less than the speed of light in a vacuum, but the relative difference between the speeds of the o-ray and e-ray can vary depending on the crystal structure and orientation within the material.

@@professionalgeologyclubI was able to tell there was something extraordinary about the way light refracted with calcite when I looked at it but I wasn't able to describe it before finding this out, I also thought it was some kind of quartz at the time but now I know a bit more about what I expected. I feel like there will be more to learn from this light interaction and applications of revelations will be revolutionary even more so than they already have been.

Is this the same hardass substance that urine can form in, say, the pipe of
a bathroom sink? Not easy finding scientific info on this particular subject,
but you'll need a jackhammer-like tool to break through it if it gets blocked.

[@professionalgeologyclub]

It sounds like you're referring to a common issue known as "urinary calculi" or "urinary stones," which can form not only in the human body but also in plumbing fixtures like bathroom sinks and pipes. However, the substance that forms these stones in plumbing fixtures is typically not urine itself but rather minerals present in the water supply, such as calcium, magnesium, and sometimes even bacteria or organic matter.
In plumbing, these minerals can gradually accumulate over time, forming a hard, crusty deposit known as "scale" or "limescale." When this buildup becomes significant, it can indeed block pipes and require significant effort to remove, sometimes necessitating tools like drain snakes or chemical descalers.
It's essential to note that while urinary stones in the human body can be composed of various minerals, including calcium, oxalate, uric acid, and others, they are not typically the same as the deposits found in plumbing fixtures. Nonetheless, both can be troublesome and require intervention to address effectively.

[@LocalCoot]

@@professionalgeologyclubThanks for replying with a great answer. Instead of limescale, however, I was
wondering if uric scale (a high concentration of uric salt crystals and acid and calcium) can cause actual
calcite to form in the pipe of, say a urinal this time, IF the flushing mechanism is not adequate and there's
a high concentration of urine and water generally left just sitting in the urinal's p-trap. Again, appreciations.
