Glass making, a pictorial how-to

Last week, when we were exploring castles and cathedrals on our trip through the middle ages, using the book Built To Last, by David MacAuley, we ended up taking a side trip through this video (and its second part) to find out how the glass for those glorious windows was made. Although I'm sure there are betters ones out there, we had a lot of fun with those videos. This week, as Calvin was gathering all the drawings, writings, and other paraphernalia of our medieval meanderings, he was slightly aghast at finding nothing about this glass blowing side trip and decided to write up a sheet of instructions for future memory jogging. There are many different ways to chronicle, and I love that he is exploring all of them, from journaling to sketching, and now a colorful combination.
