A few years ago I was teaching a glaze class at The Clay School in Lynn, Massachusetts, and decided to introduce the students to the mysterious world of glaze calculation. I poked around the web to see what programs were available now (I had used HyperGlaze from Richard Burkett since the early days of the Mac, and it has served me well, but it's based on an ancient utility called HyperCard, and its age can be a disadvantage). I selected GlazeMaster as a well thought-out alternative, and quickly became familiar with its more common functions.
As I examined GlazeMaster more closely, I realized that it was constructed using Filemaker Pro, a database application that I have been using for 10 years to create and support School Information Systems (my occupation until recently). I contacted John Hesselberth, the creator of GlazeMaster, to see if he'd be interested in having me update some of the user-interface elements since I was familiar with more recent versions of Filemaker Pro.
John generously agreed to let me work on GlazeMaster. It soon became apparent to me that the newer versions of Filemaker offered a pathway to create a mobile version of GlazeMaster while retaining almost all of the functionality of the original program. John and I agreed that this could be a fruitful direction for my research, since mobile glaze calculation software doesn't exist, and the few existing glaze database programs on mobile platforms are very basic.
Filemaker Go is a free app available from the iTunes App Store. It allows a database developed with Filemaker Pro to be used on mobile IOS devices (iPhone and iPad). GlazeMaster Go is optimized for the iPad.

Once you have FilemakerGo installed on your iPad or iPhone, you can download a beta copy of GlazeMaster Go to your mobile iDevice, and open it with Filemaker Go. The beta version will work for 30 days without any restrictions.
