Lord, how can man preach thy eternall word?
He is a brittle crazie glasse:
Yet in thy temple thou dost him afford
This glorious and transcendent place,
To be a window, through thy grace.

(from The Windows by George Herbert (1593-1633)

It’s amazing that silicon (the dust of the earth)  ground, fired, broken, pounded, fired again, and fashioned into shapes which make no sense when seen in isolation, can become a message of beauty in a Master’s artist’s hands. But in the dark it cannot been seen.

It is the light that makes glass glorious.
