This study is a detailed look at the level of understanding of fundamental ideas about blackbody radiation (BBR) among physics teachers. The aim is to explore associations and ideas that teachers have regarding blackbody radiation: a concept used routinely in physics and chemistry, which is necessary to understand fundamentals of quantum physics. In this explorative study, the responses of 106 high school physics teachers from 18 different cities in Turkey were examined using an online questionnaire during the 2014/2015 academic year. Male (88%) and female (12%) teachers with an average teaching experience of 17 years participated in this study. Teachers were asked about the concept of a "blackbody" and its radiation as well as about the closely related topics such as Wien's law and the historic effect of understanding BBR on the development of modern physics. In this study, teachers' spontaneous ideas about the BBR are depicted by "answer sculptures." The answer sculpture is a new way of representing and categorizing responses provided by the participants. The analysis of answer sculptures revealed that the physics teachers' factual knowledge and their conceptual understanding of the BBR are incomplete and even misleading. Here is what teachers we surveyed make of BBR as presented in our answer sculptures. This study is left at investigating teachers' understandings of (1) blackbody radiation and (2) the significance of this scientific breakthrough.
