Tarraliiman

Tarraliiman is a Finnish term that translates to "tar glue" or "pitch glue." It refers to a traditional adhesive made from pine tar or birch tar. This type of adhesive was historically used in various applications, particularly in woodworking, boat building, and for sealing purposes. The sticky, viscous nature of the tar makes it an effective sealant and binder.

The preparation of tarraliiman typically involved heating pine tar or birch tar, often with the addition of other substances like rosin or pitch to modify its consistency and adhesive properties. The resulting mixture would be applied while warm and would harden as it cooled, creating a strong and waterproof bond. Its use was common in areas where moisture resistance was important.

In more modern times, synthetic adhesives have largely replaced tarraliiman for many industrial and common uses. However, it is still sometimes employed in historical restoration projects, traditional crafts, or by individuals seeking to maintain authentic methods and materials. The characteristic smell of pine or birch tar is often associated with this type of adhesive. It is considered an environmentally friendly option due to its natural origin, though its application can be messy.
