Good evening you glass whiz out there. I thought I know a lot about glass, but I do not
Photo sensitiv Glass...Never heard
But I just spend a time with that vase, and it impresses me what you saw on photos what Idid‘t recognize before.
We have 3 fullbody horses, I‘m now pretty sure that ( was that Paul who mentioned it) they are acid carved. This orange peel effect is on the surface, the glass inside and beside is absolutely plain. Yes there are different thickness in the body and some parts I think are pre carved by wheel. I think they wanted the orange peel surface to give the horses a feeling and look like fur. The white bits you see is reflection.
The 3 horses by silhouette are very sharpe in lines and edges, I think they are not acid. And I ‚m more and more convinced that the red layer is a flash ore something equal.
In the fullbody horses I think in the head the carving was enhanced by hand, they eyes and ears appear very deep and sharpe.
So I learned a lot, but still we are not on trail for ID, makes it really interesting.
