Shut off the kiln when the glass has bent to the degree that you want. As a starting point, you could fire a bottle to cone 016. Cooling usually must be slow from 1100 degrees F. to 700 degrees F, which is the annealing range. The smaller the project, the faster the glass can cool through that temperature range.
A whaling ban, or moratorium, was then introduced in 1986. Even today, no one really knows how many whales are left.
