The first ash assessment notice began with the kiln-duty roll and its exemption slips. Since then, the city has moved through a source check, a public hearing and a trial at the Upper Chamber of Measures.

The current docket records 40 hearth entries; the earlier file recorded 38. The count is more specific than the first summary, but still does not answer whether the city’s largest kilns should carry a larger share of the ash levy.

A key point in the timeline was the discovery of a pair of soot-darkened brass weights used to compare household allotments. It narrowed the dispute from a general claim about the rule to a question about how the rule behaves at the site.

The levy is assessed by furnace capacity, while small workshops say capacity does not show how many hours a kiln actually runs. The current record does not settle that disagreement. The parties now share more of the record than they did at the start, though they assign it different weight.

The affected crew has tried the revised procedure under ordinary working conditions. The entry belongs to the winter count file at the Upper Chamber of Measures. The chamber’s committee must publish a revised rate table before the next firing season. The next review will show whether the change lasts beyond this docket or returns as another temporary exception.
