Since Sumerians about 4000 3000 BC had created ceramics (Heydorn et al., 1989), the ceramic production has worldwide increased, but the methodology has not suffered substantial evolution in relation to the ancient process. Research work continues to a better understanding of the processes involved and tailoring the desired properties of the final product. The most of ceramists has just worried up with the morphological, physical and structural quality of their products (Okada et al., 1986; Dubois et al., 1995; Nastro et al., 2006). However, one of the main ceramics features was not yet well concerned by the community, that is, its thermal behaviour. Urban buildings of equatorial and tropical countries are often subjected to constant solar radiation. Thus, thermal properties play a significant role in the quality of end-products. A better indoor ambient of the houses should be ever pursued. While technological properties of those materials are frequently found in the literature, information about the thermophysical characteristics of red ceramics is very scarce (Alexandre et al., 1999). In the early eighties, a new physical device to generate and detect thermal waves was proposed (Vargas and Miranda, 1988). It has been widely used in last few years as a tool to measure the thermal properties of a large range of materials (Marín et al., 2002; Faria et al., 2005). The photoacoustic (PA) technique via OPC (an open photoacoustic cell) is used to evaluate the thermal diffusivity, an important parameter that determines the light-to-heat conversion efficiency, and furthermore, it allows us to study how heat diffuses through the sample (Perondi and Miranda, 1987). The thermal diffusivity is an intrinsic property of matter. Moreover, it is dependent upon the effects of composition and microstructural variables, as well as processing conditions. Thermal properties are very sensitive to
