does not the plastque bag surrounding the splendid pebbles have a detrimental affect??? surely it causes degradation

I have a better question. See if you can guess what it is.

"Today's Brilliant Pebbles Large Size in Clear Ziplock Bag"

"Mini Brilliant Pebbles - Comes in a small clear plastic ziplock bag. This smaller Brilliant Pebbles is effective on top of CD/DVD/SACD players above the transport. Also, on top of DAC; turntable armboard; proximity to small electron tubes; and on tube traps and room lenses. Placed on the amp power cord connector on the amp end of the cord. Minis can also taped to glass doors, windows and the glass of pictures on the wall to control resonance. $79 each."

"Mikro Brilliant Pebbles - The small but powerful Mikro Brilliant Pebbles comes in a small ziplock bag and is intended for use in proximity to low level electron tubes in electronics and for all interconnects and digital cables, draped over or taped to the RCA connector at one or both ends of the cable. Also, on the power cord connector on the amp side. One or two Mikros is very effective placed on top of Quantum Electraclear & Quantum Symphony parallel line purifiers. Mikros can also be taped to glass doors and windows to control resonances. $39 each. "

I guess those low level pieces of gear you mention like artificial Belt-disapproved baggies.

"New Size! - Extra Large Brilliant Pebbles - about 50% larger than the Large size, intended for room corners of larger rooms and larger speaker cabinets. Comes in clear ziplock bag. $159 each."

I wonder if geoffie will answer the question now? Maybe he puts special sauce on the baggies and the Scotch tape.

I bet not.

thats a straw man, Emperor Dada.

would or would not the plastic affect the effect? does glass do so less, and why?

Im being serious.

Many crystals (stones) are comprised primarily of SO2. Glass containers are also composed primarily of SO2 so they have many properties in common with crystals, including hardness. What they don't have in common with crystals is the symmetrical lattice structure that only crystals(including metals) have. And it's the symmetry of the atomic structure that is the key to how the pebbles work. Consequently, glass containers will tend to resonate/ring rather than absorb energy. On the other hand, glass transmits energy very efficiently, so glass is not entirely bad as a container for the pebbles - the ringing is quite subtle compared to the overall effect. Plus the glass containers are very cool looking. Very thin plastic, on the other hand, does not have this particular problem, as long as the stones are relatively free to move and not constrained by the material. You could say it's more transparent.

SO2 is sulfur dioxide, a caustic gas. You presumably mean SiO2, silicon dioxide. However, only in the case of pure quartz can you state that it is made up of SiO2. While other common minerals do contain silicon and oxygen, the compound SiO2 is not present to any significant degree. However, these minerals do have a regular crystalline strcuure, if that matters.

Yup, silicon dioxide, thanks. I dropped an i. By the way, you left a t out of the word strcuure.

SiO2 is also the primary ingredient in minerals such as chrysoprase, amythest, carnelian, jasper and bloodstone. You could also say those minerals are simply types of quartz. Perhaps chemical composition is a little beside the point since it's the details/behavior of the symmetrical crystal structure that's the issue for the pebbles

FWIW I employ very pure crystals, pure enough to get the job done, anyway. I did say "primarily composed of"...And, obviously, different colors of quartz result from differences in trace elements. But it's all good, as the trace elements, e.g., iron and aluminum, are often crystals themselves. It's a win win!

I should probably mention I use a wide variety of crystals in the pebbles, not only quartz. Heck, I even use less, uh, common types, like sapphire and diamond.

Shouldn't you be standing out on a ledge somewhere?

LOL!

It's an Internet Law that if you point out an error in someone's post, you will make an error in your own post. :-)

The ledge view is much better than the BS view you seem to find yourself in 99% of the time
