I ordered Bloxygen from WoodCraft. I was going to use this to preserve my Tung Oil. I use it to fill the can of Tung Oil and let the air out, otherwise it will turn into jell.

Where can I get this stuff? Or is there a substitude?

Just use an air duster can and it will do the same thing.

Yes, and it seems to work pretty-well. Here’s some instructions:

Varnish Storage hint: Each time you use the can of finish, before capping, be sure to flush out the airspace in the can with Kensington Duster II, Dust-Off, or some similar product. Just make sure that the product contains no air (actually oxygen is the culprit). Most computer, office supply, and home supply stores carry aerosol cans of several different brands of compressed air duster. Make sure your can has the 5” tube for directing the gas into your can or bottle. To use, insert the tube in the valve, then insert the other end of the tube into the can (but not below the surface of the liquid), lean the lid on top and release a gentle stream of gas into the can to displace all of the air (a couple seconds generally does the trick). Slide the tube out of the can and immediately tighten the cap. By the way, don’t be surprised if the can tends to collapse on storage. The duster gas slowly dissolves in the varnish, creating a vacuum. But if no oxygen is present, the varnish will stay fluid for literally years. You might want to transfer the varnish to a glass bottle with a tightly fitting lid and flush well with duster for long term storage (glass obviously won’t collapse under the vacuum). When I open a new, large can of finish, I routinely pour most of it immediately into a glass bottle, flush, cap, and put away for storage. The rest of the can, just the amount I expect to use within a week or two, goes into a smaller glass bottle, which I flush and cap after each use.

Thanks teenagewoodworker, Greg Wurst and Lew. I am going to try the air duster. I still have some laying around in my office.

I am going on vacation for two weeks and I need to be sure I have Tung Oil when I come back.

We need to be sure to put the airduster away from kids, the stuff is deadly.

You can also add clean glass marbles (Hobby Lobby, Micheal’s etc.) to the reduce the headspace in the can. You can reuse them in the next can you open. Might have to try the air duster trick too though.

I’m frugal as well as rustic.

It seems silly to me buy gases to save finishing products.

I buy Tung Oil in volume, five gallons at a time.
I redistribute the TO in to more convenient sized containers.
Some are one gallon in size and some are about a single job or two in volume.
I use recycled containers that I get for free.

I also have some accordion pleated plastic containers that can be collapsed down to the size of the remaining contents.

unless your climate is different, 100% pure tung oil won’t solidify. That’s one of the problems of using tung oil as a finish is that it takes days or weeks to dry and usually needs help from some type of drier.
The guy i buy my tung oil from buys it by the 55 gallon barrell and then sells it by the gallon to other people.

Any good wine store will have that gas. It is used to take the oxigen out from an open bottle to avoid oxidation and ruining the wine.

Whenever I finish using varnish, paint or shellac, I press a piece of saran wrap down to the surface of remaining material. It keeps the air from contacting the stuff…less creative, but it works for me. -SST

Hi PaBull:

Are you talking about real tung oil or “tung oil finish”?

So called “tung oil finish” is usually diluted varnish and most often does not contain tung oil.
Tung oil finish will jell when exposed to air it is exposed to air because of the varnish.
