Beckstoffer has figured out that a certain altitude--from about 600 to 730 meters--in the right part of Lake County has a heating-and-cooling cycle similar to Napa's.
Scafetta projects that the global climate may remain approximately steady until 2030-2040 (as was observed from the 1940s to the 1970s) because the 60-year cycle entered into its current cooling phase around 2000-2003.
Regarding the possibility that the global climate will soon enter a substantial cooling phase attributable to a weak new solar cycle, this may ultimately prove true also.
The glaze is applied to a fired stoneware vessel, which is then fired again in a repeated cycle of six stages of heating and cooling where precise temperatures matter a great deal: either over- or under-firing will spoil the effect.
