Topic: Cut Glass Wine Frosted Bowl Faceted Stem

Thanks I’ve used those photos before when trying to convince on this subject and they are ‘items I’m sure are mechanically abraded’....maybe not everyone else

I would be very interested to see your examples if they were posted.

What if acid is applied to the surface with a brush? Bet you would get lines then...

But I suggested that many moon ago and was told the brush would dissolve

Just a question of finding the right material for bristles.

They would’ve needed a time machine for that

See page 200 of the Grove Encyclopaedia of Materials for:

- Information on Acid etching and how it was done on plates (metal plates)

- The fact that acid could be applied using a brush or a feather

Also just read a snippet information from the Rijksmuseum in one of their catalogue publications stating that Acid etching was widely used by mid 19th century for decorating fine table wear that was too thin for wheel engraving:

I would have thought anything of organic matter would have disappeared rather quickly, in the presence of acid.          Perhaps the acid was diluted.

Thanks for all the replies.
I would agree with Paul as to the age as it may explain the weight of the glass.

I have also tried to take some close up pictures of the frosting and cutting.

Thanks Roy

I'd see that as acid etched after cutting    Anyone else see something different? 
Just wondering if I need to re-evaluate my thoughts on the way some surfaces have been treated.

quote from m  ..........................  "I'd see that as acid etched after cutting  "   ...you may be correct m, but on face value you'd imagine that common sense would dictate it should have been the other way round.             I see why you've made the comment though, after all the acid effect appears to be bleeding into the mitre.          Perhaps the acid bite was deeper than we thought and the bleed shows how deep the bite went into the glass.  ?
