I was wondering if anyone knows or can point me in the right direction to determine the value of glass for windows and/or drinking vessels, etc. in 15th century England. I work with a historical society and am looking to expand my presentation on trade goods value.
I tried searching on here and came up nil.
Thanks in advance for any assistance!

The glass in the great east window of York Minster Cathedral cost around £56 in 1408 I believe. But that was a huge expenditure and I seem to remember that they paid John Thornton extra for a rush job!
