Thank your for your reply. I have seasoned several molcajetes this way and found them very workable. However this metate has more and deeper holes than I have ever seen. I tested an area outside the usable part with a grinder. This is very hard material and to make the surface as usable as one would want it would take hours with a grinder without assurances that there would not be equally sized holes under the surface ground off. The metates I have seen in Oaxaca did not have surfaces like this one. Unfortunately I am not in a position to drive there to pick up a new one. I was hoping that the map discussed in the 2005 string would help me find a feasible source and would really lke to see if the map was published. But thanks again , I really appreciate your input.
