Steeping in different sized jars

[Wingsfan0310]

I found this interesting. On Saturday I made a 120ml batch of TFA RY4D with AP in it. I took out two 8ml vials for use. I shook all 3 each day and opened them up to let them have a breath of air just a few seconds. I just looked at them today and couldn't believe how much more color the one in the big jar has. I'm assuming because it has a lot more surface area (plus a lot more air inside the bigger jar) allowing it to interact/oxidize with the air.



I'm not sure how well it comes out in the picture but they both started out pretty clear. The big jar now has a nice yellow tint to it, the vial has hardly changed color.

Cheers,
Steve

IDK - Could this be because with the 8ml vial you are looking through a smaller quantity and it just seems lighter/less colored?

Try dispensing another 8ml from the large jar and then compare the two 8ml vials to each other.

Also see if the one in the jar taste different then the one in the vial. Let us know!

I thought you were going to say just that opposite - that the smaller jars have more color.

I suspect Spazzer might have a point - with the bigger jar you're looking through more liquid. But I'm curious as to if that's right.

It may have a something to do with it but I looked at them yesterday morning and they were pretty close in color. Looking at them in person they don't seem to be even close to the same shade of yellow (the picture makes them look closer in color than they do to the naked eye). The big change seemed to happen since yesterday morning. I will pull out another 8ml vial from the big jar and compare the 2 vials to see if they are different. Probably won't do it till tomorrow though. I'll try to get a picture of them both together.

Also see if the one in the jar taste different then the one in the vial. Let us know!

Unfortunately 1 of the 2 vials I pulled out on Saturday magically disappeared in a cloud of vapor . I want to leave this 1 alone (filled almost to the top) to see just how much different they get over another couple of weeks.

PS They have both been stored in the same cabinet in the dark other than when I pull them out to shake them and burp them.

I drew out 7ml out and put into another vial (same vials) and it seems like you are right. There is a slight difference (new vial is slightly darker) but not like comparing the older vial to the big batch. Unfortunately my phone cam isn't good enough to really show the smaller difference. I'm going to try a take a few more pics under better lighting and if I think it shows the smaller difference I'll post it.

Now I'll add when I made the stuff on Saturday it was almost clear (in the big jar) so I still do believe the bigger bottle helped. I say that because I shook it very well before taking out the original vials. Because there is so much headroom, when I shake the big jar it turns almost into a white froth (the whole mixture, not just the top). With the smaller vials filled close to the top, shaking them just as hard only produces a few bubbles in the mix.

PS I wish I would have taken a pic of the big jar when I made it on Saturday. I think some would be surprised at the color change in only 4 days. Went from darn near clear to a very rich yellow/gold

Look at all that air in the big jar. Air makes the nicotine in the juice oxidize faster and that's why your seeing the darker color.

 

[Wingsfan0310]

That was my original premise in the first post Danny. I figured it was the Nic oxidizing with the air because of the both the volume of the air in the container coupled with the greater surface area.

Thanks for the update.

The color change could be the nic oxidizing, or just a natural color change of the juice.
The different colors could be from steeping in different size jars too, IDK

I have a 50ml bottle of RY4 Double with a little AP and Tobacco Absolute that was mixed back in October and it has a distinct yellow color also ( a little darker than yours, i believe). I don't remember what the color was like when it was mixed.

Color change can happen with steeping. I mix a TFA Strawberry Ripe and Kiwi Double juice that is essentially colorless when mixed, but after a UC steep turns yellow.

I'm not sure if oxidation is at work here. Did the following simple experiment just to see:

Took out 10ml of my nic base in a 30ml clear glass bottle. Mixed the same amount of base with flavorings in a second 30ml bottle. After 10 days the nic base had not changed color while the flavored liquid had turned yellow. There might be a chemical reaction occurring between the nic and the flavors; or else could the flavorings be expediting the oxidation?

Just out of curiosity, I did an experiment to see if the color change was due to oxidation or not. It turns out oxidation was not the cause.

What I did: took out 10ml of my nic base in a 30ml clear glass bottle. Mixed 10ml of flavored liquid with the same base in a second 30ml bottle. After 10 days the nic base had not changed color but the flavored liquid with the same nic base had turned yellow. There might be a chemical reaction occurring between the nic and the flavors; or else the flavorings could be expediting the oxidation.

Yes thats know as seed steeping. If you use a small amount of already steeped mix and mix it in a new unsteeped batch it cuts the steeping time down by 70 - 80% don't know why but it's a fact. Ive been seed steeping juices for 6 months now and every time it's the same thing. If you read my blog on steeping you will see mention of it. All it takes for this is 5 - 10% old mix to 90 - 95% new mix.

Thanks Danny, I will have to try that. I vape mostly tobaccos and sometimes patience is in short supply here.

I'm sure it was the flavoring maybe also the Nic, or a combination of the 2. My point was with all the air and extra space, the liquid literally turned into a white froth when shaken. That color change happened in only 4 days. So I think it accelerated the change. I'm assuming something reacted with all that air in the container and the mix itself (oxidation).

Hi Steve, It'd be interesting to see if the same oxidation would occur with the nic base alone being shaken vigorously (That question is coming from the nerd in me...)

 

[Wingsfan0310]

I don't believe it would, especially in only 4 days. Now I'm thinking I may have to do an experiment

Cheers,
Steve

You have a lot of shaking to do I am not motivated enough.
