Heritage conservation is not like sharing cookery recipes, that’s why we cannot offer you a quick solution for a standard damage.
Blog posts, tutorials, videos and other published information intend to simplify complex concepts for others to understand, but that does not mean that actually treating an object is affordable for any non professional, at least with the same results.
Heritage conservation requires studies and experience. Even the most simple treatments are so because who made the diagnosis does have a remarkable training and experience, and not the other way around. That is, not because it seems very simple it is advisable to try a Do It Yourself. Just like a doctor would prescribe an aspirin in a context, and nevertheless would caution against it in other conditions in which the same aspirin would have fatal effects. Doctors are valued for their cappacity to make diagnosis which derive into the health improvement, not because of their basic skills in measuring the blood pressure or inject a syringe. Likewise in conservation: the success of the treatment lies in the diagnosis more than in the execution itself (which is also crucial).
Besides, the same treatment performed in one way or another, with some tools or others, shall have an abundantly diverse outcome. It is not professional nor accountable from the conservator to provide any directions because of the lack of information about the resources, skills and knowledge of the person who asks.
Furthermore the given description about the artefact and its damages might not be the appropriate one. Sometimes most relevant features are missed. The sent images and videos can easily lead to wrong interpretations even for the trained eye.
If the damage or the object are not worth spending a conservation treatment, then it’s better to leave it as it is, rather than making a bigger mess.
In any case, this is a private conservation studio and therefore we cannot assess for free to non-customers. We recieve a large number of such requests, and unfortunately we cannot attend them all on our free time.
If you need assessment we’ll gladly make an estimate for you particular case. OnLine mode is an option as well (most commonly for preservation issues) and tailored tuition is also a possibility. And, as always, the presence-based activities are the most fruitful, take a look at the scheduled workshops.
Maybe your demand has already been replied in some other blog post, make sure you have not missed it in the advanced search.
Rather than trying a hazardous DIY restoration, the most intelligent option is to hire a professional conservator. That’s what we are here for!
