When it comes to truth in advertising, we’re a bit skeptical (G much more so than I am; as I am still susceptible). We’re the kind of people that like to conduct our own research and testing. So even though I’m a BIG fan of violet glass, I wanted to dig a little deeper. Plus, most websites that sell violet glass all write the same thing, which I find rather irksome…

Why am I even talking about violet glass. Well, as a matter of fact, we use violet glass for our apothecary products, like our organic breath spray, Peppermint Mist, and organic Argan Oil.

Is it more expensive? Yes, yes it is. Does it have its own challenges? Yes it does. Is it worth it? Absolutely! Here’s why.

First of all, not all glass is created equal. What makes violet glass special, and why we chose it for our products, is that it blocks out most visible light (the exception being the violet end of the visible light spectrum as well as UV-A and infrared light). This is important because visible light, along with air, is the primary cause of decay and degradation, aka photodegradation (which includes oxidation).

Since we use natural and organic ingredients, without synthetic preservatives, it was critical to find the right packaging. And we didn’t want to sacrifice function for form. Don’t get me wrong, the violet glass is stunning. But it seems like the trend for all natural beauty products is light, clear, and white; where you can see the stuff inside the bottle, jar, and pouch. I mean, it looks so pretty—seeing pale pink salt and vibrant blue liquids! However, that is precisely the problem. If I can see what’s inside, and you can see what’s inside, then everything (including sunlight, i.e., visible light) can also see inside…and wreak havoc, or, at least, make the stuff less potent.

So, back to violet glass. It differs from clear glass in that it serves as a natural filter from ‘harmful’ and ‘damaging’ light; the kind that degrades vitamin-rich oils and delicate, beneficial compounds. This concept is not novel. Did you know that beer is bottled in amber glass to keep it from smelling and tasting skunky? Prior to amber glass beer bottles, beer was bottled in clear glass. But if beer in clear glass was left in the sun, the taste would change. Scientists discovered that the UV rays broke down the alpha acids in hops leading to a reaction that resulted in beer smelling like skunk spray. And so, amber glass makes beer good. (If you’re interested, here’s a fun experiment and scientific explanation regarding Physics and Green Beer Bottles.)

And this brings me to the reason for this article. In our infinite curiosity, we carried out our own mini-experiment putting violet glass to the test. The manufacturer, of course, has its extensive testing. We put a fresh cherry tomato inside a violet glass jar, dated the jar, and left it for a little over a month.

Then, we opened the jar.

Wanna know what we found?

Ta da!

Yes, the tomato was as fresh a month later as it was when we first put it in the violet glass jar! There are some caveats. First, I didn’t leave the jar in the sun. I left it in our pantry. Second, I didn’t leave it in there for seven months. Though, I did stick the tomato back in and now have the jar perched next to my desk exposed to sunlight. So, I’ll give it another few months! Maybe I should put in a new fresh tomato…?

I guess my point is, yes, there is sometimes truth in advertising and violet glass packaging really is superior; at least for some things.
