What's a bovine? and what exactly is milled grain?

What's the boil test? 

Well..that's exactly what I did, but they told me "yeah, we just took this hide at one of the sellers, we don't know which one, nor which exact type of leather this is". I think he said it's veg tan, but not so sure anymore.

Boil a cup of water in the microwave. Then throw a tiny scrap of the leather into it.

If it just gets wet (but otherwise holds it's shape), it's chrome-tan.

If it shrivels up like a piece of fried bacon, it's veg-tan

Bovine....Mooo....moooo..   Porcine....oink oink   ....and yummy , but thats for  a totally different  thread. 

The milled bit is where its basically  put in a machine and rotated , and dried . The lines in the grain  etc. become bigger, bolder,  softer, making it totally awesome    but can't be cut with a (belt) strap cutter or burnished , believe me...and us....we've  all tried it. You can try it yourself...until the cows come home  ..ha ha !!     sorry

ah, so many words for cow in english :D

And yeah, I noticed, I had to cut straps using ruler and stanley knife, it's impossible to use anything else. But still, the leather is a blessing, it's really good one.

With that white core to it I'm betting it's chrome tanned.

It looks like nice supple stuff but I have no idea how you find it's origin.

Best of luck to you scoring more!

 

Also, bovine is cow and milled is that grain on the hair side, the wrinkly parts. Milling usually makes the leather softer/more supple.

Did the hot water thing on it, showed no special movement at all, so I don't think its veg. tanned.

Try to get one of these rotary blade knives. They cut this type of leather much easier

Actually, I'm not working often with this kind of leather, but I also discovered what's best to cut with (so far): fresh new blade from the box. Cuts like a butter, is working for me just perfect tho.

The rotary knife is good for cutting any thin leather, up to even 4mm thick. It doesn't pull the leather so you get a nice straight cut the whole length

Wow, now I just learned something new! What I've done previously is wetted a scrap of the mystery leather, and tried to stamp or tool it. If it won't stamp or tool, it's obviously NOT veg-tan.

And yes, rotary knives work great for thin, stretchy leather. But just like with a regular blade, you have to make sure the blade is SHARP!

Experience talking ?

No, I still have all 10. Even after running saws for 45 years. But a girlfriend almost lost a bit of hers. I like to learn from OTHER'S mistakes.
