Update:We have spoken with Bullseye and they have let us know that they do not have any formulations that have borosilicate glass in them. The etching rate of their glass is wholly dependent on color and not on any addition of borosilicate to the mixture. We apologize if there has been any confusion on this. It is always best to test your colors for etching before committing to the full project.
As many of you already know, Bullseye has just released their newest Catalog Number 12. It’s a beautiful catalog with great items, pictures and flow.
It’s wonderful to see their continued perseverance and persistence in our art community. Bullseye has always been a company that we, here at His Glassworks, look up to. They have a true heart for the art community; believe in forwarding education and pushing the boundries of what glass is capable of doing.
We’re very pleased to see them landing on their feet and not just standing, but continuing to run forward after the last few years of trouble that they have had.
We have many customers who use Bullseye glass in their work and we’ve found a few interesting things over the years with some of our materials and how they interact with Bullseye.
Specifically our Vari-etch materials used for acid frost etching glass surfaces.
We’ve found that a few of the Bullseye colors can sometimes react a bit differently and not etch uniformly with other colors. Sometimes this is a factor of the type of color; Red and Black in particular have a harder time etching than many other colors. This is most commonly just the amount of material and hardness of the glass itself compared with other colors.
Sometimes there are some formulations that actually contain a little borosilicate glass in them. Acid etch material will not frost borosilicate glass. It will still etch the materal (i.e. remove glass from the surface), but it will not frost it.
Some of Bullseye’s formulations may contain a small amount of borosilicate glass in them. Before you begin to prep for acid etching on your Bullseye material, you may want to check with them to see if any of the pieces you have used contain borosilicate glass in them.
Don’t fret if this is the case. Just remember that you may have to sandblast your pieces first for a uniform frosting and then acid etch the surface with Vari-Etch to achieve a fingerprint proof surface on your glass. Once a piece is sandblasted, the Vari-Etch will still etch the glass and fingerprint proof it and the sandblasting allows a uniform surface appearance on the glass.
