Crystal Growing: "Magic Salt Crystal Garden" from Mrs. Stewart's® Bluing

http://www.mrsstewart.com/pages/msbframe.htm >> follow links to Magic Salt Crystal Garden

Apparently a longtime classic do-at-home experiment. You may also find the rest of the site itself interesting.

    http://www.crystalgrowing.com/index_d.htm

Like Peter Keusch's Didactics of Chemistry site, Udo's pages exhibit the classic Teutonic virtues of thoroughness and attention to detail. You'll find crystal growing recipes, kits [see separate entry below], pictures, crystal shape laboratory, and so much more.

Crystal Growing Kit from the Smithsonian Institution

http://www.smithsonianstore.com/asp/browse/productdetails.asp?CategoryId=497&ProductID=1497

"This Smithsonian Exclusive allows you to grow such crystals as pink quartz and golden citrine at home. Both educational and fun, the kit includes eight bags of crystal growing chemicals, nine crystals and geode growing cup molds, casting compounds, safety glasses, six display pedestals and instructions. Age 10 and up."

cat #1497  $32.00 [plus tax] to nonmembers

Space Age Crystal Growing Kit from The Tech Museum Online Store

http://store.thetech.org/spacagecrytg.html

"Join Astronaunts on board The International Space Station and grow these 6 sparkling crystals, Single Emerald, Emerald Cluster, Emerald Geode, Ruby Geode, Ruby Cluster and Single Ruby. Includes CD ROM  Ages: 12 and up"

cat #5503 $22.00

Crystal Growing Kits from Udo J.A. Behner

http://www.crystalgrowing.com/xx_kits/xx_kits.htm

"These crystal growing kits are designed for ages of 14 years and older. If it would be designed for ages under 14 it would be a "chemical toy" and subject to harsh regulations regarding type and amount of chemicals included. Following these regulations I could only produce an almost worthless gimmick kit. So the age border of 14 doesn´t mean it might be to difficult or to dangerous for any younger. The ALUM kit may be used by kids 10 years and older, the other ones with about 12 years and older. However adult supervision should be provided !
If you are going in depth, varying growing conditions, colors, crystal shapes, growing crystal combinations, its a worthwhile pastime also for adults.
Each kit will provide material for the growth of a number of single crystals and crystal specimens. Refillment packages are available, see CHEMIKALIEN (so far only in German !).
The procedure of growing crystals is quite easy, you disolve the chemicals in hot water and let the saturated solution cool down or you use the evaporation or the
supersaturation method.
First results can be obtained within 24 hours. You don´t need any special equipment; just regular kitchen equipment and household ware will do it. (And yes it's microwaveable !)
The ready crystals make up a nice collection or nice gifts."

US customers can only obtain these while Herr Behner is touring the US -- see details at website; EU [EEC] customers can order without problems. Four different kits available, each priced at US $19.95 / DM 29.50

Crystal Growing Kit from Omni Resources

http://www.omnimap.com/pscience/xtl-kit.htm

Designed for ages 12 to adult, these kits each contain a 10-oz. chemical packet and full instructions. Each kit grows crystals up to 4" in diameter. Sixteen kits ranging in price from $14.95 to $74.95

Crystal Growing Kit from the Science Alliance

http://www.sciencealliance.com/Merchant2/graphics/equipment/kits/crystalgrowingkit.shtml

"The kit provides an ample supply of chemicals to grow three different types of crystals.  Includes formula sheet for crystal growth, and text entitled "ROCKS AND MINERALS" which contains comprehensive data on crystals and lattice structure.  This kit contains Aluminum Potassium Sulfate, Cupric Sulfate, and Nickel Sulfate."  $60.00
