One also has to bear in mind that most of our pyrometers are not 100% accurate some may be out by 40 or 50 degrees so slowly cooling through the strain point makes sense.... Also the annealing temp between one colour of Effretti glass and another may be different by the same 40 or 50 degrees.... This means that their strain point is also different .... So unless you know that your pyrometer is accurate and you know the exact strain point of your glass.... SLOWLY COOLING the kiln is a more effective way to make sure your taking the stress out! (The bigger the bead the more slowly the kiln needs to be cooled!)
