It seemed to us that the whole problem of Olmec trade and the interrelationship of the preclassic sites in Mesoamerica offered an unusually favorable case for the method of grouping via paste-compositional patterns based on neutron activation analysis. As a start on this program we include here the analysis of six preclassic Tlatilco figurines, and we compare their analyses with those of two modern specimens and touch upon the archaeological conclusions possible. 

The crow s foot could not be attributed to any of the paste compositional groups. Glazed bowls are known to be transported in stacks with the Crow s Feet still in place to prevent breakage (32). It is likely that the crow s foot does not represent the local production of glazed pottery, but is possible evidence of trade. However, it is still possible that the crow s foot could have been made from a different paste than the glazed pottery and be a local product. 

Petrographic analysis was conducted of a sample of sherds from Groups 1, 2, and 3, of the INAA paste composition groups. The petrographic study was conducted for the purpose of comparing the current INAA analysis to previous petrographic studies of Early Islamic ceramics (33). 

The ceramic samples selected for discussion in this chapter are those of Mexican production. As reported by Maggetti et al. (5), the Mexican majolica production includes both calcareous and noncalcareous paste compositions. This chapter will focus on the calcareous Mexican majolica. The following ware types were selected to examine questions of the assignation... 

Printing Ink. A colored or pigmented liquid or paste composition that dries to a sohd film after application as a thin layer by printing machinery. 

Electrical wiring of enzymes incorporated into carbon paste composites... 

The number of strands per length of quick match and the amount of pasted composition per unit length depends on the use, but the most popular one has about 0.8 g strands and 8.0 g composition per Ira to form a length of 4 mm diameter with a burning rate of about 30 mm/sec in the case of a black powder composition. 

Material and Methods Aqueous Food Pastes Composition... 

A nonaqueous dentifrice gel and/or paste composition is disclosed in U.S. Patent 6,331,291 Bl, cited as a thixotropic and smooth-flowing substance. Brookfield viscosity values are reported in the patent for illustrative examples of the invention using Spindle no. 6 at 10 r/min and 23.5°C. The preferred viscosity range is 75,000 to 150,000 cP.

The above electron micrographs of soaked pastes indieate that PbS04 crystals retain no memory of the initial 3BS crystals, which has also been reported by other researchers [8,9]. On the other hand, the mierographs in Fig. 3.6 show that considerable quantities of 3BS crystals remain unsulfated even after 5 h of soaking in H2SO4 of 1.25 rel. dens., i.e., there is a traee of memory of the initial paste composition. The remaining 3BS crystals are involved in the proeesses of formation and exert an influence on the organization of the PAM strueture, and hence on the performance of the battery.
