Please Note: GlazeMaster runs on Mac OS 10.10 dubbed Yosemite by the folks at Apple. I have run it on a Yosemite Mac Mini and it looks and runs the same as it does on earlier versions of OS X. I will test it on an iMac in a few days, but expect it to do the same on that machine. 


GlazeMaster is a glaze calculation software program (and an excellent database) designed specifcally for studio potters. It runs on both Windows (XP up to and including 8) and Macs OSX (up to and including Yosemite). GlazeMaster is priced for a potter's budget at only US$40 including an 85 page searchable pdf User's Guide and the software for both Macs or Windows.

Fully functional downloads are available that let you test the program for 60 days before you purchase it. Or take a tour of the program.

Upgrades to GlazeMaster 3 from GlazeMaster 1.0, 2.0, 2.1, 2.2 or 2.3r3 are free and available here. Upgrading is essential for potters running one of these versions on a Mac before you upgrade to the Lion or Mountain Lion or Mavericks operating system. For more detail, click here.
