Finally got a clean pull on that cobalt blue marble after three tries

The first two attempts just cracked at the neck, but keeping the punty warmer on the third go made all the difference. Anyone have a trick for keeping the color from shocking when you're working with dense rods?

Try pre-heating your marver in the kiln too. A warm steel table can suck the heat right out of a gather and shock the color. Letting everything stay hot, not just the glass, keeps the temp more even.

Oh man, my friend had the worst time with some dense violet glass last year... she kept getting these tiny fractures right at the gather. She started putting the whole rod in the kiln for like ten minutes before even starting, just to soak the heat all the way through. Said it was a total game changer, no more stress cracks. She still works slower with those colors though, lets everything settle between steps.
