An egret appears above the letter “R” in a work in this material by artist Philip Simmons. Faces are reduced to “masks” in several works in this material by Julio (“HOO-lee-o”) González, (15[1])this material’s “father.” This material, used for the entrance to the Pavellons was also used for the 32 balcony railings of the Casa Mila. (-5[1])“Puddling” was used to create a work (-5[1])in this medium depicted in (*) Simultaneous Windows by Robert Delaunay. Maurice Koechlin (“KUSH-linn”) and Émile Nouguier (“noo-GHEE-ay”) designed that work in this material which surpassed the Washington Monument when revealed at the 1889 World’s Fair. For 10 points, the Eiffel Tower exemplifies the (-5[1])“wrought” form of what medium crafted by blacksmiths? ■END■ (10[1]0[2])
