Before this reading seminar, I knew about the 3 types of rocks known ( sedimentary, metamorphic and igneous). After this seminar, I walked away knowing how these types of rocks are determined as a building material and I realized there was more to stone than the aesthetics. What I also got from this seminar is the different ways stone is used into building material and how not only its found but how it is quarried and what quarried even means.  This seminar was really helpful because it developed a kind of understanding and analysis I probably wouldn’t have reached on my own time reading.
