National Naju Museum's free 'Sparkling Gilt-Bronze Crown' class is for kindergarten or daycare groups of five-year-olds, not individual walk-ins. The listing gives Tuesdays and Wednesdays, April–November 2026, 10:00–11:30, a 90-minute class for 15–23 children from one class. Children learn about a gilt-bronze crown and make their own, then complete a related follow-up activity at their educational institution. The official instructions require calling to agree on a date before submitting the group application. Confirm the session and actual acceptance with the museum. A class teacher must stay with the group during the museum lesson, and the teacher is asked to complete a mobile feedback survey after the follow-up activity.
