BTO

Got some beaver tails rendering in a glass container. There's definitely a layer of oil, maybe 3/4" thick on top. It looks like it's got a reddish tinted to it, not the tar black look I've seen before. Is this normal ?

All the tail oil I have rendered is very dark in color typically.

Give it more time

That's the hard part

That is one advantage of age. A guy can fill a black 5 gallon pail with chunks of tail, and then forget that you did it for a couple of years! I just found a bucket out back and it had better than a gallon of beautiful dark tail oil.

Friar tuck is correct fill your container and forget it. And yes I mean fill the containers Rendered materials shrink, tainted materials swell. Im guilty to I want to start drawing as soon as possible.That reddish tint means its still got blood and need more time to separate.100% pure bto will not freeze it will get a grainy look but still be soft and sticky. Bto that's been rushed will get ice crystals in it

do you not intend to say solid Ice in it ?? Mr. Tony??

We're still a couple of weeks away from our first frost more than likely. Once we get colder weather, should I bury the container or just let it ride ?

no, put it in your hot box...…….a dead freezer with a100w light bulb for heat

how can THAT be...…..you were sposd to start the process in late spring or early summer.

Larger heat lamp bulbs are better , the bulbs farmers use on baby animals being born in winter , late fall !

honestly I know misery isn't the coldest state but mine stay outside the entire winter! If I was concerned with mass production id put it in my hot box. Mr Ken incomplete bto wont freeze solid it has enough oil content to stay in a slush form.

Be patient and let if finish. It’s worth the wait.

Really ? Mr. Tony it will and can solidify at 0 F and below 0 F !
I found that out several years ago on the 20 buckets I had at the time . When temps got down to -32 below zero , frigg'in freezing !

process by which the beaver tails' oil is rendered dictates how much resistance it will have or not have against the elements , unless you are in Hawaii . You wearing Palm Trees Mr. Tony ?? lol

there are substance that will not freeze even at -40 f , but they are few within the trapping industry .
if you didn't see that the anti-freeze in semi-trucks were gelling up under the freezing temperatures , breaking down on the interstates a few years back , and that anti-freeze is synthetic to withstand -40 to -50 below zero .

rendered beaver tails is not synthetic but will freeze at the right temperature .

Possibly the Government has substance that will resist -9000 F , gotta check !

Ken im not talking about the liquids in the rendering vessel it can and does freeze solid . Im referring to that reddish tint bto ive put my unfinished bto in the freezer at -20 its gets thick like putty but never has it got solid. The purest stuff get the consistency of a thick gravy in the freezer. If misery hits -40 or -50 im moving farther south!

Mr. Tony , your being mis-led by your thinking buddy , I am referring to the thick blackish rendered oil (depending on Process by which it is rendered) , determines it's resistance to the elements and how far below zero it will go before freezing to gel , ice or ice cube , It gets frigg'in Cold -30 , -40 degrees below Zero your boots will freeze to the earth and you will freeze , hypothermia , you'll be an Ice Cube , If you don't get next to the big wood stove in a hurry !

throw a glass of water in them temperatures of -0 to -40 F and watch it instantly turn to ice/sugar crystals right before your beakers .

NO not the liquid remnants buddy , junk water , left over slop water , I call it pee water with a beaver smell .

Snapped this pic today. In the pic it looks black but held up to the light it has a translucent reddish black color. Will it continue to work in the cooler temperatures?

Here is what mine looks like after brewing 2 years, including sitting outside in the frozen winter.
Not sure if it was dumb luck, but this fox was caught the first night, in the first trap that I used it in a dirt hole.

If using a quart mason jar does BTO have to b gassed off or left sealed?

not in my experience, but I don't add any bone or meat or fur, only tail meat chunks

can it be put in a plastic bottle after its done, or is glass better?

Oils like that and other sun rendered oils are fine in my experience to hold them in plastic. Far less dangerous to accidental breakage. I have had some oils of that nature for 40 plus years without breakdown or compromise of any kind.

thanks bob!

Starting to become a believer.
I have set a total of 6 traps in 2 locations, and used a couple different lures. In 5 days I have caught 2 fox, one at each location, and both on the tail oil.

John is correct but I add it all bones and a very tiny amount of hair. I'll burp my jars until it starts producing oil, then I just leave them loosely screwed on. Like maybe half a thread. Flys here wont try and mess with it after it forms a layer of oil.. It is still gassing very slowly. I've lost a few bottles of pure oil because I filled them to full and sealed them up tight!

Good work FriarTuck.

Maybe I missed it, but I wonder if BTO works for bobcats.
