In my 25 year career as a scientific glassblower, I have used decals from at least four different manufacturers. All of them were sufficient, but one person stands out on quality: Hendrixson.
I first encountered the Hendrixsons in 2017 at the American Scientific Glassblowers Society (ASGS) annual symposium in Austin, TX. Since they were a new vendor, I thought I’d give them a try. As a glass engineer at one of the largest consumer products manufacturers in the world, I was always in the market for good solid vendors. I have found Hendrixson responsive and the turn around times to be quite fast.
Most important thing is the QUALITY! HGD are SECOND TO NONE! They apply like butter, don’t tear and fuse into the glass like a dream. Colors are as vibrant and strong as before they are fired. Del personally works with you to get your design to be EXACTLY what you want and delivers them when you need them.
