Tamminen graduated form Aalto University in 2015, and her MA thesis studied how the internet tutorials of the ceramic surface techniques can be a part of a studio practice. The purpose of the study was to consider the mentality in the sharing of the ceramic material knowledge via the surface technique tutorials. In addition to the technical content, it’s notable how professional ceramic artists use the tutorial sharing internet platforms to connect with other professionals.

The lecture is based on published articles on her blog that has been read internationally over 38 000 times.
