Winding down

The pyrometer reads 1036 and dropping.As far as I know,crystals stop growing at around 1060- the glaze being thereafter too sticky to let them expand- but this glaze is so runny that I'm trying a few extra temperature twiddles down to 1020,just to see what happens:if the glaze is runny enough,we might get some "annular" rings round the edges of the crystals.Gas pressure seems low-I must check the tank level.It's enough for these low-temperature frolics,but probably not enough for the next firing.I shudder to think what the next gas bill will be.
