Stoneware from a one-wheel garage studio in Mexico City: a numbered kiln log every firing, glaze recipes in grams, and a monthly kiln opening.
Test tile list: cups 3, 5 and 6 from the November batch went before 11 a.m. Cup 4, the one with the sanded pinhole, is still here at the lower price. Reply with 4 and it is yours. Load is tomorrow at 7:40. Feldespato has been told to stay out of the glaze buckets.
First pick on the six November cups closes tonight at 8 p.m. Two are spoken for. From Monday 9 November the other four go to the Test tile list, first reply wins. The door cup waits for December's Seconds shelf at 150 pesos, trimming tools removed.
Next firing loads Tuesday 10 November with a witness cone in the middle shelf, because log #31 caught the door side running half a cone cold. T-08 goes in too: same blue ash, two-second dip. Kiln log #32 on Friday.
Loaded Tuesday, 3 November, 7:40 a.m. Unloaded Friday at noon, after the pyrometer read 60°C and I stopped arguing with myself about opening it early.
Monday, 5 a.m., glazing day. The load is tomorrow at 7:40, so here is the plan before the horno gets a vote.
Eight grams. That is how much more glaze this cup carries than its siblings, and it explains most of what you see.
The blue glaze came out gray on the first firing. I changed one part ash to two parts cobalt and put the test tile on the top shelf, where the kiln runs hot.
I trimmed this bowl too thin on the first pass. The foot looked elegant on the wheel and nervous on the table, so I left it to dry, came back the next morning, and gave it a little more weight.
