My advice is that if you're interested in keeping this pelt for more than a novelty item, say, a wallhanger or anything else taxi-related is to skip the eggs and find a tanning solution instead. In my personal opinion, egg-tanning is just asking to ruin a pelt. It's not a tan, it's nowhere close to being a tan, and as explained by other members here it's a primitive method of making leather. There's a reason brain and egg tanning is mostly used on hides, and not furs... If you're a beginner looking to tan your first pelts or you're looking to tan a fur of high value to you, Rittel has a tanning kit available on their website that is easy to use and suitable for beginners. The more high-end tanning solutions used by taxidermists can be bought online or by shipping pelts out to commercial tanneries. I've actually seen this touted as another method. Yes, I once read that you can "tan" with mayonnaise. : George is a long-time member on the forums and knows what he's talking about. If you come to a forum like this, ask a question that really has no place here beyond being linked off-site to a website catering to it, and then get mad when a professional tells you that it's not a correct way to tan a pelt... there is really no reason to get so mad. If someone truly wants to learn, be educated, and discover the error of their ways, they need to be open to the criticisms of others who are more experienced than themselves. OP came here asking for advice on egg-tanning, was told that it's not the correct way to tan a pelt and isn't even a true tan, and fired back by calling people know-it-alls. If OP knew what he was bringing up, why would he have asked the question? Why would he have come to a taxidermy forum asking for advice? Beginners need to be guided to the right directions so that they don't ruin pelts. I would feel extremely guilty if I told a beginner on here to brain-tan that roadkill fox they found, only for them to ruin a nice pelt and become heartbroken over it. Guide the newcomers in the right direction. The right direction in this case is to stay away from egg-brain-mayo-breakfast tanning and use actual tanning solutions if you have any desire to create anything but hard leather.
