Glass Art and Etching News Updated information on glass art, the craft of etching, sandcarving, and the engraving industry with glass, metal, or anything.

Here’s some more answers to glass etching questions I got in my email from Dianne.  These are all great questions and I appreciate talking about them. 

She showed me an image of a glass etching that was being sold through ebay.  Although, I wish I could post the image so everyone can post their views and understand what I am talking about, but its a copyright protected image, so I’ll explain from a different pattern example.

As you suggested, the etching might be etched using an acid and it very well could be.  The etched glass mug looks nice, but its hard to determine from the small image.  It has an interesting look and it appears as if the majority of the design is sandcarved into the glass.  From what it seems, the internal areas of the overall sandcarved design seems to be frosted lightly.  There are many different techniques that could be used, and here are just some ideas of what they could have done by referring to the example pattern below:

Usually, you will have a black area and a white area of a pattern.  By using a two stage glass etching technique, the whole graphic is etched including the black and white areas.  This is a very simple pattern found on here for free.  It depends on the processes used and the etching you showed me is probably one of these variations:

1. Using Acid Etching Processes- The glass you showed me could have been carved deeply into the # 1 black areas with a strong acid.  Then the # 2 white areas of the pattern could be lightly frosted with a less potent glass etching cream.  This can also be done in a vise versa fashion.
2. Using Sandblasting Processes- The other process could be done by sandcarving the glass pattern’s # 1 black area.  Then the #2 white areas can be sandblasted lighter with a reduced air pressure.

I hope that helps and I talk about it more in the information manual.  Feel free to leave me a response below or any other questions anyone has.  Take care.
