1633 july the 3rd. I have blown three windows,ten cups.It´s hard work because you need high lung capacity.1633 july the 4th.I have to mix sand and chemicals and blend them in a crucible then I have to melt it ,then I blow through a metal pipe.I use special tools to shape the glass and the glass has to be cooled down slowly or it will becomes brittle.1633 july the 5th.To rest my hart I only work six months a year so,i´m on my break for the next six months.1634 march 1st my first day back and were now making better glass then lime glass,now where making flint glass it is better in all ways.
