Now that the point has been cleared up, from a personal point of view, I would prefer the logo licence fee not to be included in the course fee as I have no use for any logo. (No advertising - including sign-writing).
If the course fee were increased to cover this I would be paying for something I have no need for.
Conditioning replaces the natural tanning oils evaporating out of the hide. The smell of leather comes from these oils. If not replaced, leather will eventually dry out, become brittle and crack. Think of these tanning oils as microscopic, lubricating oils. If you look at leather under a microscope, the fibers look like a pile of rope that's all tangled up. Tanning oils coat these fibers allowing them to bend, move and slip across one another. These oils keep the leather soft and supple. Without lubrication, leather fibers will become stiff and brittle. When repeatedly flexed, stiff, dry fibers will simply break and the leather will develop cracks.
No Steve unfortunately not. This is one of the myths about leather.
The oils that are put back into leather during the tanning process are usually well sealed in and only under rare circumstances do they come out. What does dry out of leather is the water/moisture content. This is why water based cleaning products are essential, why cream and oil or silicone based products do more harm than good and why protection is more important than 'conditioning'.
This will be fully explained when you come on the course.
I think the term many professionals like is rejuvenating.
I agree with both Steve and Judy on this one.
The Moisture( fat liquors and collagens in an emlusion) are what keep the fibers lubricated.
Some tannerys do use levels of oils and silcones in the process to lubricate.
This differs somewhat to what we as professionals can actually replace for several reasons.
It would be wrong to say that no amount of of the "well sealed" moisture escapes. It is a breatheable natural fiber. I wouldn't oversell this point Judy. In other words your telling everyone that a dry rotted piece of leather still has all its natural oil that were "replaced" That would be inaccurate.

It is always difficult to put everything down on forums like this and we do not always have the time to devote as we are always very busy with training etc. Sorry if I gave the wrong impression.
This is why training is so important as all these things are discussed in great detail.
We were just trying to open the debate on the issue as so many people still use the terms conditioning and feeding.
