Blowing glass into wood - GIF

[ranald]

Though most glassblowing is done between 870 and 1,040 °C (1,600 and 1,900 °F), "soda-lime" glass remains somewhat plastic and workable at as low as 730 °C (1,350 °F)

Thanks, the comment was meant to be rhetorical. I once almost missed a flight as I was watching glass blowing for around 4 hours and was mesmerised. Cheers
