Wood finishing oils - Linseed & Tung - info links

Thanks for taking the time to do that, guys. Another thread to squirrel away.
 
Thanks, ddean

Last link has some good info--seen it before but kinda forgot about it.

Haven't looked at the other two yet.
 
Found Lin-Speed website/home-page.
Someone had mentioned the product recently.

www.lin-speed.com

To quote in part:
" "GB" Lin-Speed is a laboratory perfection of linseed oil. "GB" Lin-Speed is not a concoction. It is in fact, linseed oil refined to the point that the oil acquires the admirable qualities of good body and rapid dry. Ordinary linseed oil never really dries. The "GB" Lin-Speed refinement process removes the non-drying linseed parts (called Foots)."

But, their application page when mentioning components just says:
"CONTENTS: Boiled linseed oil, petroleum thinner. .......Contains no resins, rosin, shellac, varnish, lead, wax or silica."

"I don't know how many people sweated all night trying to duplicate the magical ingredients in "Hoppes" gun gleaning oil. It has this wonderful intoxicating smell, and all it ever was was plain old petroluem oil with some (of all things) bananna oil (?) mixed in for smell. "

"> I recently was going through a stack of old ww mags when I came across a short article that claimed you could "clarify" linseed oil to reduce "tackiness". You do this by pouring linseed oil into a clear glass container, then adding two iodine crystals. Place the container in direct sunlight for about two weeks and a "considerable of gunk" will settle to the bottom. Decant off the clear liquid into a clean container, and you have "clarified" linseed oil.

"Bob J. asks if anyone has clarified linseed oil per a process he came across and if it is worthwhile. No I haven't done it, but if it was worthwhile wouldn't we be able to buy such clarified oil in our local borg?
On the other hand, maybe we could at one time. The name Watco Oil is still around, but the original formula and company is not. That original Watco Oil was linseed oil that had gone thru some sort of additional processing that altered it fairly substantially; I can recall having tried it once and not being too impressed. Maybe that process was Bob's clarifying? If it was, does the fact it faded away say something about how worthwhile it was? Maybe in general, but certainly not to everyone; I've seen some lamentations about the fact you can't get that original formula any more. The current Watco Oil is a tung oil variation. The original Watco Oil (maybe the current one too?) came in a clear or in various wood colors. I'd tried the clear and, as I recall, found it to do about zip to enhance a finish. "

"-----about WATCO
I have used it for years. It works great!!!! I do Find the MIN WAX antique oil finish to be very similar. and it may build just a tad quicker"

"As I recall, the history of Watco Danish Oil, sans dates is:
- Owned by Watco, Inc.
- Bought by Minwax (/Thompsons, now part of Sherwin-Williams) in NJ
- Reformulated
- Some Darwin-Award-Candidate burns his house down due to stuffing oily rag in a pile. Sues Minwax, wins.
- Minwax discontinues product because of liability.
- Similar-to-original formula developed by General Finishes, WI (still selling as General Danish Oil)
- Name bought by Flecto, CA, from Minwax
- Reformulated back to original formula; back on the shelf at your local borgs."

"[Ryan wrote, I don't normally use linseed oil(because it provides zero protection) except as an additive to some oil/varnish built up finishes, but one Linseed oil product that I like very much is Tru-Oil by (I think) Birchwood Casey. It builds very quickly into a deeply glossy and protective finish and will look like polyurethane if you aren't careful, but it is wonderfully easy to apply by just "dotting" small amounts on and hand-rubbing them in. Artistic use of steel wool and hand rubbing can leave a limitless variety of matte/glossy/satin textures to your heart's content.]

For years I have used Tru-Oil to refinish gunstocks and I agree that it is very easy to apply and to manipulate to any desired appearance. I then read that Frank Klauz recommended Waterlox (a polymerized tung oil) for furniture. When I opened the can, I recognized the smell. This was confirmed by using the product. If not identical to Tru-Oil, it is awfully close. Perhaps the only difference is the use of tung oil instead of linseed oil in the formulation. In addition, Waterlox is much less expensive by the quart or gallon than the little bottles of Tru-Oil. I simply wipe it on with a cotton rag. It usually requires 3-4 coats. Then knock down the gloss with 0000 steel wool and wax. The result is a beautiful, and protective sheen. "

Pretty funny...kinda like all the "amazing" nicely scented dish soaps.

One of the links in the thread Fed mentioned discusses how hardening oils like linseed and tung oil dry. It is a complex process involving free-radical chain chain reactions and atmospheric oxygen. Iodine [two iodine atoms relatively weakly bonded together) quickly reacts in sunlight to form two radicals (meaning that each piece/atom bears a reactive unpaired electron]. It will initiate polymerization of the linseed oil. [or other radical chain processes]. So little is needed because the on going chain reaction makes new radicals.

If iodine is added to raw linseed oil, this recipe may produce something like boiled linseed oil. The heavy-metal salts added to non-heat-treated "boiled" linseed oil products must act better than iodine or they'd use iodine instead.

It is likely that adding iodine to boiled linseed oil will just make it go bad faster. Also, remember, that any halogen (fluorine, chlorine, bromine, iodine) is a great way to induce rust--FAST.

Maybe. I'd -guess- that iodine would be more expensive to get/store/use.
But, lots of sources of iodine to experiment with.
Tincture, salt, water purification tablets, and surely many more.

I discovered that RE Chlorine a few years ago while clarifying
some corrundum (sapphire) samples.
Poured muriatic (dilute HCl) acid into a ceramic bowl (no cover)
on a 2nd floor balcony and added the mineral samples.
Next day I checked the samples and also found the aluminum and steel
on the sliding door-frames were all Very corroded from the fumes.
Oops.
 
These links is in the violinvarnish.com link, but I figured Id directly link just in case people missed them.

First heres a link to some articles that explain linseed oil, clarifying it, curing it,and foots; turpentine, resin, and the famous cremonese violin finish that I really like. :D http://www.violinvarnish.com/about.htm

Here is another link to another line of products they have, for old style finishes (made the old fashioned way) http://www.triedandtruewoodfinish.com/standards.htm
 
Just rediscovered something I've forgotten numerous times.

An MSDS (material safety data sheet) can provide very good info
about product's composition.

For example:

One (1) Waterlox Sealer/Finish product indicates on the description page that it contains "26% solids" and not much more info.
But the MSDS for the item shows that it contains (by weight):
Stoddard Solvent <70%
1,2,4-TriMethylBenzene <5%
1,3,5-TriMethylBenzene <5%
Cobalt Namhphenate <1%
BUT, no mention of the source of the solids in the MSDS

Elsewhere it does say "Waterlox finishes are a special formula of tung oil and resin ". And elsewhere states it contains Mineral Spirits. And further states it has advantages over 'raw tung oil'.
-
In comparison, Tru-Oil MSDS lists (by weight):
Mineral Spirits <57%
Modified Oil (mixture) <33%
Linseed Oil (mixture) <11%
Which accounts for the total weight of the product.

FYI, I looked up Stoddard Solvent and found this info(at):
http://cisat1.isciii.es/HEC/CSEM/stoddard/exposure_pathways.html
"Stoddard solvent is a colorless, flammable liquid that is insoluble in water. It is volatile and has an odor similar to that of kerosene or gasoline. This description applies to a variety of other petroleum distillates including white spirits and mineral spirits, which are similar mixtures containing the same types of components as Stoddard solvent. However, the boiling ranges and ratios of hydrocarbon components of these three petroleum distillate fractions differ. "

Based on the MSDS I think I'd consider the Tru-Oil somewhat safer to finger-rub and breath.

When I get time I'd like to get more of the MSDS info on the products we're discussing here.
 
I've been meaning to post regarding Minwax Tung Oil finish. I'm currently doing a trial of it on a 15" Bura Sirupati. I called Minwax and they faxed me an MSDS. It lists mineral spirits 65%. It is fairly thin in use and penetrates well, due to the high percentage of solvent. I'll withhold judgement until I finish my little project, but so far I don't dislike it compared to Tru-Oil.

My bottle of Tru-Oil is getting old and kind of thick. I thinned it with the Minwax. Seems to work ok.
