It states that this effect was only found when using more dilute solutions than we use. 5 ppm was effective, and the standard used these days is usually 10 ppm. There are other concerns I have heard raised by some sensitive individuals, about the possibility of chemicals leaching from the plastic due to the low pH of the silver solution. In my humble opinion, this is a distinct possibility that might affect a few individuals who are extremely sensitive to those particular chemicals. In that case, using and storing in glass containers is a good option, providing that at least a 5ppm solution is used (according to the above research study).

Re: CSPlastic or Glass bottles
In both brewing jars and storage bottles, some portion of the Colloidal Silver tends to plate out on the inside of the glass. When this happens in the brewing jar, it seems to interfere with the brewing process. When this happens in the storage bottle you apparently end up with a weaker silver product. I much prefer plastic for brewing and for storage.

Re: CSPlastic or Glass bottles
I use both. I have had anaphylactic attacks from some small bottles of water, presumably from chemicals that have leached into the water. It is unpredictable and rare. I have not had that happen with the large cloudy 1 gal bottles. I use glass for brewing and storing whatever I am using, but decant into water bottles for mailing (and sometimes storage).

There is a misconception that has prevailed in the market place that glass is better. The idea that glass containers are better for storing products that contain silver has never been proven scientifically. But in fact, it has been reported in other studies that glass may have a detrimental effect on silver products. Test Work I have been conducting biological studies for 3 years, in the laboratory of a major private institution, on the use of silver products to kill and inhibit the growth of bacteria. I have conducted thousands of tests on numerous strains of pathogenic bacteria. In the testing I have completed, I have used both glass (5 ml glass test tubes) and plastic (Falcon 5 ml polypropylene plastic test tubes). In some of the test work we found that there was a difference in the amount of silver that was needed to kill the bacteria when glass was used versus plastic test tubes. In order to make sure this was the case, it was decided that the MIC tests (Minimum Inhibitory Concentration) should be replicated by more than one person and a direct comparison was made. The MIC tests were performed in triplicate in both 5 ml 13X100mm glass test tubes and 5 ml Falcon polypropylene plastic test tubes. Results of the bacterial (MIC) tests showed that Staphylococcus aureus was inhibited at 2.5 ppm when the MIC test was performed in the plastic test tubes. S. aureus was inhibited at 5 ppm when the MIC test was performed in glass test tubes. This suggested that the material with which the test tubes were made, specifically glass or plastic, may have effected the results of the MIC test. Numerous other tests were also completed using larger concentrations of bacterium and in those tests it was found that there was no significant difference at all between using the glass test tubes versus plastic test tubes. Other Studies The studies that I performed are not the only tests showing that glass, in some circumstances, may have a detrimental effect on silver products. It has been noted in another independent study that has been cited by other researchers that silver can adsorb to glass (Chambers 1960; Thurman 1989). With this in mind, it may have been possible that the silver could have adsorbed to the surface of the glass test tubes reducing the concentration of available silver interacting with the bacteria, which resulted in having to use a higher amount of silver to kill the bacteria when the glass test tubes were used. Conclusion In the test work I have completed as well as in other available studies, it was found that glass may, in some cases, have a detrimental effect on silver products. While it can be said that glass did not always show the detrimental effect, it can also be stated that we found no problems at all with using the plastic instead of glass. Our tests, in conclusion with the other available independent studies (1. Chambers et al. and 2. Thurman et al.), would suggest, by inference, that silver products should not be stored in glass containers which could reduce the available concentration of silver, but rather in a high quality plastic container.

CSPlastic or Glass bottles
I've used plastic bottles for 5 years for CS thats stored for up to a couple of months. It doesn't causes any deterioration that I can detect by measurements or actual use. I use HDPE bottles. Thats the waxy type of plastic my demineralised water comes in. Theres some suggestion that PET plastic (Coke bottles etc) may be better but its not conclusive. The good thing about plasic bottles that have contained demineralised or drinking water is that they don't have to be washed out. Just empty them. You'll never get them any cleaner. Of course we keep these larger containers of CS in a cupboard. We keep a brown glass pint bottle on the sink for daily use. David You asked: I'm wondering whether PET plastic bottles are OK or not to store my CS. PET bottles were the favorite of Ol' Bob, one of our more beloved members and experts who passed on a couple of years ago. As I recall, his testing showed no detectable degredation or contamination of the CS after extended periods. Several years back I bought a six-pack of 20 ounce bottles of Purified Drinking Water from a local Wal-Mart, drank or dumped the contents, and put them to use for storing CS. They're just fine, and I never needed to do anything but rinse them out, initially. There was no problem with taste or smell as you might have with a bottle that was used for soda pop or other strongly flavored and sweetened beverages. Be well, Mike D.

CSPlastic or Glass bottles
Hi there, I hope that I'm not repeating a question that has already been asked recently. I have a SilverPuppy generator, and I'm wondering whether PET plastic bottles are OK or not to store my CS. According to the instructions that came with it, it says PET plastic bottles are OK. Then I came across this web site (http://www.silver-colloids.com/Papers/FAQ.html#glass-bottles) which says that home-made silver always consists mostly of ionic silver, and therefore should be stored in glass bottles. Now I'm wondering if storing my EIS in plastic bottles has been a waste of time. Also, if plastic is bad, does that mean putting EIS into a glass spray bottle (which has a plastic inner straw) is not recommended? Another question ... I have two children (a 2 year old a new-born). When is it safe to start giving them EIS to ward off colds? I'm concerned that with lack of selenium in their diets, they wont be able to eliminate the silver from their bodies. Thanks in advance!

Re: CSPlastic or Glass bottles
Why do you think their diet is deficient in selenium? Any newborn is probably best off with her mother's milk, in any case ( just my opinion, unless there is some infection that needs treating). Others have said they use it to treat children. The storage jars seem to be a matter of personal preference. I use both. I also keep EIS in a nasal spray bottle in my purse at all times, my son has taken to keeping a plastic spray bottle of it in his car.
