Description

Dendritische kwartsDendritische kwarts met zijn boomachtige, varenachtige vormen en takken is een zeer interessante en aangename steen. Hoewel het dendritische patroon lijkt op een gefossiliseerde plant, is het in werkelijkheid niet organisch. Wanneer vocht en ijzer zich vermengen ontstaat er oxidatie, beter bekend als roest. Oxidatie is een alledaags verschijnsel. Het gebeurde zelfs in edelstenen. Sporen van vocht en ijzer of mangaan zaten vast in kwarts, wat vlekken

Dendritische kwarts met zijn boomachtige, varenachtige vormen en takken is een zeer interessante en aangename steen. Hoewel het dendritische patroon lijkt op een gefossiliseerde plant, is het in werkelijkheid niet organisch. Wanneer vocht en ijzer zich vermengen ontstaat er oxidatie, beter bekend als roest. Oxidatie is een alledaags verschijnsel. Het gebeurde zelfs in edelstenen. Sporen van vocht en ijzer of mangaan zaten vast in kwarts, wat vlekken veroorzaakte die op bomen of takken leken

Dendrieten worden meestal gevormd door mangaanoxide. Sommige van de andere mangaanoxiden die dendrieten vormen, bevinden zich in de hollandiet ngroep van mangaanoxiden. Het zijn coronadiet, cryptomeleen en hollandiet. Twee andere mangaanoxide-mineralen die dendrieten vormen, zijn romanechiet en todorokiet.

Het woord dendriet komt van het Griekse woord "dendron", wat boom betekent. Vandaar de naam Dendritisch of Dendrietkwarts.

Didn’t come with all the Parts - Essentially Worthlist Return in process. Huge inconvenience
Product came with everything but the rubber pads that receives the screws so it’s essentially worthless upon arrival. Now I have to go out of my way to go to UPS to send it back and process a return which will take 7 business days until I can receive a refund. I was excited for this package too what a complete let down !

Excellent privacy shade.
Color: Coal Black
This delivered on exactly what it promises. So happy with the quality for the value. The shades are a fabric, nylon like, that are attached with a pocket on one end and velcro that adheres around the bar on the other. This was incredibly easy and straightforward to put together. Every piece was clearly labeled, coordinated with the instruction sheet, and fit perfectly. Honestly, I wasn’t planning to leave a review but I was so impressed by how clearly labeled and well explained the instructions were that I felt compelled to note it. Especially for anyone who doesn’t like putting things together, or is used to subpar instructions, this is leagues above the rest. It’s such a simple build anyway, but after buying so many things that barely fit as they should, this stands out. It is lightweight and easy to move. Offers privacy when opened, then can be folded out of the way. It looks exactly as pictured. No complaints, it’s a solid item and worth the price.

Decent quality for the price
Color: Grey
Decent quality for the price. Other privacy screens were extremely out of my budget, but this looks and works just fine- I just needed something simple to place behind my couch to hide some clutter. It took me about a half hour to assemble, but it was easy enough. It might be due to my carpeting, but I don't trust that the screen would be stable enough to stand freely without falling. Thankfully my plan all along was to wedge the screen between the couch and a box of clutter anyway, so for me it works as l'd planned!

Overpriced but effective.
Color: Cream
I happened to get lucky and get a warehouse deal at an additional 30% discount. Even at $25, it feels a little overpriced. But it was easy to assemble and serves its purpose. If you line the Velcro up exactly, the panels sag, if you stretch past even, but where it still grips, they look pretty ok. It is very light and does fold very compact for easy storage.
