Please Note: GlazeMaster is now only sold as a "download". You can download the free trial copy, get it running, and then if you wish to buy it, come back to this site within 60 days and pay for it. The installation code will be emailed to you. I have done this to save material and time and be able to lower the cost to you. Also CDs are becoming "dinasaurs" in the digital age--some computers no longer have a CD drive. In addition to saving shipping cost, the price of GlazeMaster has been lowered from $50 to $40 passing most of the savings on to you.


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 Mavericks). 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.
