Tahkumine

Could you clarify what you mean by "tahkumine"? The word appears in multiple contexts and languages, and I want to ensure the article matches your intent. For example, in Estonian the root tahk can relate to crusting or coagulation, but the exact sense of tahkumine can vary by field.

If you can specify the domain (for instance, medicine, geology, food science, metallurgy, linguistics, or a general dictionary sense) and the desired tone and audience, I can produce a concise, neutral wiki-style article under 300 words, including a clear definition, etymology, key contexts or examples, and any notable usage.
