Is this pure enough to grow crystals for science project?

I am no scientist, but would guess the answer is yes. Label says 100% aluminum sulfate. Aluminum 17% and sulfer 15%. (Don't you also need potassium to grow crystals?)

The crystals are sort of like ice, not exactly white and not really clear. They do get more clear when water is added.

I covered mine with sand . I'm not sure what the crystals are . I really haven't tried it yet . I live in Florida and we are waiting until fall .

I used filtered water to restore the natural beauty of the crystals (they do come very dirty). Here's how: Put the crystals in a laundry mesh bag, fill a 5 gallon bucket with cold filtered water, dip and rotate the bag in the water for about 20 seconds, allow crystals to dry. You can clean yours crystals with water and there will hardly be a noticeable decrease in its volume. Do not use soap.

I believe the directions say to leave it in one place. Moving it while the crystals are growing is apt to jostle the small crystals, so you'd get more smaller crystals rather than a few large ones. That said, we moved ours from the kitchen table to a less frequently disturbed area soon after mixing, and that didn't seem to affect the final results much, if at all.

I don't know 100%, but these are packed pretty tightly together and are designed not to come apart very easily... I wouldn't use this as the only growing medium, but I bet if mixed w/ potting soil or something it would work pretty well.

I would say yes because it is chauked full of minerals but since Im not the manufacturer, I am not 100% of that.

As far as I know, as of the build of the unit I found in the bin, the crystals were made of glass, including the long round tubes between the little crystals. Very fragile. I kind of wish they did make those out of plastic. Don't know about current production. You might contact the manufacturer for more current information.

My research is that it is definitely "lead crystal"....just that it does not go through the lengthy process to render it as thin as most other very fragile and light weight crystal that you pay big money for. Check out the company "Longchamp in "Arques, France" if you still want more information. I'm no expert but the above comment is my findings many years ago,.

Yes, I had good luck with this. You have to be aware of the product's limitations. The granules expand to many times their original volume when exposed to water. One method that worked for me was to take a big screwdriver and use it to bore a narrow, cone-shaped hole into the dirt, as far as possible from the plant itself. Then I dropped some of the dry crystals down the hole, stopping an inch or two below the soil's surface. I then covered the rest of the hole and repeated the process two more times per pot I probably used too many crystals, as a few worked their way to the surface. No worries--the plants did well.

I don't know what the crystals r made of but r white when I hang it at first and by day 30 they turn yellow. And they work great! The bag was full of water and the crystal were clumped together and yellow. Don't hesitate to buy, these work!!!!

Yes sir! I only mixed it once with milk, the rest of the time it was water. It's got a slightly chunky (tiny pieces of product) consistency, but that's the BCAA crystals I believe. You should be all good!

I bought this quite awhile ago but as I recall it is a powder bot crystals. I used it for baking and it worked very well !

Hi David,The crystals are REAL. The quality of the chandelier is good and I would recommend this product. Be careful, I dropped one on my tile and it shattered!

It is normal and ok. I moved the majority of it into a glass mason jar and set it in a pot of hot water to dissolve the crystals. I left a little "as is" for toast. : )

It will dry too thick I think for the crystals but you could try a sample to see if it meets your approval it will dry clear.

No, unless you're very certain that it won't get absorbed. My understanding is that crystal still contains aluminum, but it's in a salt form that sits on the surface and doesn't get absorbed. I assume it could have some negative effects if absorbed, so I try to make sure I wash it off if it gets on my hands, etc.
