Tumacacori Polychrome is glazed blue on both sides of bowls and comales and  
can vary in color from blue to gray. The only ornamentation is just below the  
rim or brim of the vessel. I have not seen one that is not blue on both 
sides.  These were a much nicer grade of Majolica than the Puebla Tradition or 
Aranama  Tradition (what Jack and Anita Williams call Abo'-Aranama Tradition). On 
this  point, the potters' guild set standards for three grades of Majolica; 
yellow  (plain white), common, and fine. As the guild lost political favor 
during the  Mexican Republic, the Majolica factories experimented and broke 
tradition to  produce pottery that competed well with European export pottery. I 
believe this  becomes evident between 1810 and 1830. Mark Barnes goes into detail 
in the 1970  publication, Mexican Majolica in Northern New Spain, by proposing 
three  time divisions for the polychrome ornamentation. I believe the height 
of the  Mexican Republic era produced Majolica can be marked by Tumacacori 
Polychrome.  While more pieces from your site may prove me wrong, I think you 
cannot  make too much out of one slightly grayer sherd because the range of color 
 variants includes gray tints of blue.

I have  already looked at these gorgeous illustrations & photos.  Not  sky
blue definately grey blue.  Not burned.   Its not  Tumacacori that I can
tell.  Have you seen Tumacacori that has a solid  area at least 1 cm wide on
both sides of the vessel?

(Has anyone  ever made replications of these vessels in ceramic?)
