That is the sudden shrinkage of cristobalite—a crystalline form of silica—as it cools past 420 F (220 C). Cristobalite is found in all clay bodies, so care must be taken to cool the kiln slowly as it moves through this critical temperature.

So doing the math says bisque - in about 10-12 hour range. Glaze - probably 5-9 hours. Cool down can affect glaze finishes, generally rapid cooling tends to make things glossy and slower cooling can make things appear more matte as crystals have time to grow.
