Why to avoid Brown Amber Bottles for stash jar use

Visible light has a wavelength in the range of 380 to 740 nanometers. This only represents a small portion of the full range of all the frequencies and wavelengths of the electromagnetic spectrum. See below for a diagram of the full light spectrum. MyPharmJar Smell Proof Miron stash curing jar is the only type of glass curing jars on the market guaranteed to enhance all-natural substances.

Light Wavelength Chart

Notice that directly to the left of visible light is UV — known as UV light or ultraviolet radiation or — which has a slightly higher frequency than visible light. It is the UV light that most commonly affects the integrity of a bottle’s contents. A classic example is “skunky” beer: when beer in a clear glass is exposed to light, the taste goes bad, due to photo-oxidation. This is one specific example of a “photochemical” reaction, a chemical reaction that is caused by the absorption of light by atoms or molecules. There are many different photochemical reactions that can take place. A common photochemical reaction problematic in the packaging business is photodegradation, which is basically a breakdown of molecules initiated by the absorption of light photons. UV light, which has higher energy than visible light, often accelerates photodegradation.

Brown or Amber glass blocks all wavelengths of ultraviolet light including the beneficial areas of UV-A which provide microbial protection. Long term storage depends on the right spectrum of light in the correct levels. This is why it took 10 years to develop the glass formula that MyPharmJar uses for their smell proof stash jars.

The color of any object is the frequency of the wavelength that reflects from the object’s surface. Amber and brown are a low-intensity, low-frequency hues: basically, darkened yellow, orange, or red. The low-intensity blocks out some light and the hue enables some frequencies in the red to the yellow range to pass through. Lower frequencies are effectively blocked, including ultra-violet frequencies. this is why amber is deficient for protection versus MyPharmJar Smell Proof Stash Jar

Not all substances will have a photo chemical reaction when exposed to light; those that do are considered “photosensitive.” Examples of things that are photosensitive include many vitamins, many medications, beer, hydrogen peroxide, alkali salts, and photographic film. In fact, so many different things in the pharmaceutical industry are photosensitive that brown and amber pill bottles and medicine bottles have become the norm but could be much improved if they were packaged in a MyPharmJar Miron stash jar versus amber glass. The packaging world has much to learn about optimal glass for herb storage

MyPharmjar is the best glass Miron stash jars that work by permitting only beneficial light frequencies to pass into the contents of the jar enhancing all-natural substances. No better storage container exists for herb storage on the market.






  1. I simply want to mention I am just newbie to weblog and absolutely liked your web blog. Almost certainly I’m planning to bookmark your site . You certainly have amazing writings. Many thanks for sharing your web-site.

  2. I’ve been surfing online more than 3 hours today, yet I never found any interesting article like yours. It’s pretty worth enough for me. In my opinion, if all site owners and bloggers made good content as you did, the web will be a lot more useful than ever before.

    I needs to spend some time learning more or understanding more.

    Thanks for magnificent information I was looking for this
    information for my mission.

  4. I bought a 500ml sensor jar about six months ago and it is my only go to for keeping my herb fresh, either bud or just ground herb stays fresh with no nasty or dried taste. I recommend mypharmajar to anyone who is a avid herb smoker and just opening the jar for them to smell and see is an eye opener as most will say “my herb don’t smell like yours!” I will never use anything else.

  5. Great web site and blog articles. I can tell you have put a lot of time and effort into this website. Keep up the great work

  6. Howdy I am so delighted I found your site, I really found you
