So the Getter activation range start at 20ºC ??

that is deposited on the glass.
The later is active at tube working temperature ( 100-200 degrees celcius ) and may be done in an household owen.
150-200 celsius is ideal. Man, my book is useful for everything! See:So the Getter activation range start at 20ºC ??
