Shot Glasses - Positive and Negative Glass Etching

I am etching shot glasses as favors for a friend's wedding and I offered her a choice.  I used the same design but used 2 different methods and products to etch the glasses and I got very different looks!

Disclosure:  I receive compensation in the form of free product and/or pay from companies and manufacturers in return for creating projects showcasing those products.  While the content of my blog is influenced by these products, my opinions regarding these products and projects are my own. 

Basically positive etching is cutting a stencil, weeding out the design elements and marking that area.  With negative etching, you remove the opposite areas of the pattern and use the design elements like stickers to protect those areas of the glass.

Glass#1 is an example of positive etching.

I created a stencil by cutting the design in etchall® etchmask using my Silhouette Cameo.  I weeded the vinyl and covered it with transfer tape.  After burnishing really well I peeled the release paper from the back of the vinyl.

 To prepare the glass I washed it and then wiped it down with rubbing alcohol.  Once it dried I applied the stencil and burnished it onto the glass. I removed the transfer tape being careful to leave all the tiny bits behind. (Tip:  Instead of pulling the transfer tape up and away from the surface, I kind of roll it and peel it.) I then covered the exposed part of the glass with tape.

Glass #2  To be honest this is a bit of a hybrid because I did weed the sugar skulls the same way.  (The stencil design included a thin outline of the skulls that I removed in the first design but left in the 2nd.)  The text on the glass is actually the best example of the negative etching technique.

I cut the same design a second time but I weeded it differently.  I covered the design area with transfer tape, burnished it and then peeled off the release paper from the back of the vinyl.

I applied the stencil to the 2nd glass in the same way: clean, apply, burnish, and peel!

The first glass treated with etchall® etching crème.  I covered the stencil area and set it aside for 15 minutes.  The second glass was submerged in a plastic cup filled with etchall® dip 'n etch. The etching liquid is about 1/8" under the lip of the glass. I did not etch the inside of the glass.  I added a roll of quarters on the inside to keep it submerged and I left it for 15 minutes.

After 15 minutes the etching crème and the dip 'n etch were returned to their original containers because etchall® is completely reusable!  I thoroughly rinsed the glasses before removing the stencils.
Note:  Do NOT rinse in a porcelain sink as this is an etching product and it will remove the glaze!

And here they are!  Positive etching on the left and negative etching on the right.

And the bride and groom chose...Glass #1.  Time for me to start cutting some stencils!
