Seal (8 mm tubing):
Remember: Hot glass looks the same as cold glass!! Don't burn the top of your bench, put your hot glass on the ceramic mats.
DO ALL YOUR WORK OUTSIDE THE FLAME!!!! Use the flame to soften your glass. Keep your glass rotating in the flame, for even heating.

Heat the ends together, remove from heat, push them together then slightly
pull them apart.

from forming.

Heat the seal until the glass collapses, then remove from heat and blow
a slight bulge.

Slightly collapse the bulge, remove from heat, and blow the seal to the
diameter of the surrounding tubing.
