Didymium glasses? for vitroeus enamelling?
Perhaps some one can enlighten me.
I did enamelling with kilns torches and muffles for 7 yrs,
researched enamels and techniques in depth and never heard of eye
protection with glasses.
Now glass blowers use glasses to reduce the orange/yellow glare from
flamed/torched sodium glass Is this what your referring in to?
Never hada problem looking at enamel melting up to 1000deg c. over
