Support Glazy

Why Support Glazy?

Glazy is 100% free for use by anyone.

Glazy doesn't spy on you, sell your information to third parties, or otherwise profit on you in any way.

Glazy is the only online glaze calculation software that promotes sharing recipes and test results so that potters can learn more about ceramic chemistry while verifying and improving results.

How to Support Glazy

The best way to support Glazy is to use it! Uploading images of glazes, verifying existing recipes, and sharing your own recipes helps Glazy become a more trustworthy source of ceramics information.

Glazy will always remain open and free. But the Glazy code takes many hours each month to write and maintain, as does providing support to users, creating tests, and importing new data into the database. The web servers that Glazy runs on cost more as Glazy grows. Therefore I am adding some features that are "Patron-only", enabled only for those who financially contribute. Those who contribute help to support the thousands of teachers, students, and all those unable to contribute.

Free for Student & Teachers

If you are currently a student or teacher, simply register with a .edu email address and you will automatically be given 12 months of Patron status for free. If your school doesn't use the .edu domain, just send a photo of your Student ID or other proof of enrollment to derek [at] glazy [dot] org.

To avoid the hassle of monthly contributions, just make a one-time donation. Users will receive the Patron badge & special features at the rate of $2 per month.

For example:

  • One-time $2 contribution for 1 month of Patron status
  • One-time $24 contribution for 12 months of Patron status

Subscription donations of at least $2 per month also get the "Patron" badge and special features listed below. NOTE: Please allow 24 hours for your Glazy Patron status to be updated.

To make a one-time or recurring donation to Glazy using Paypal, click here or on the "Donate" button in new window

Glazy Patron Special Features

Those who pledge $2 per month via either Patreon or PayPal receive a special "flame" badge that appears next to their username in Glazy. Whether you donate $100 or $2 a month, every patron gets the same badge. This badge unlocks some special Glazy features.

Target & Solve

Just open a Recipe, Material, or Analysis in the Calculator and click the "Target" button. In the new recipe, add materials you would like to use to reformulate the target analysis, then click "Solve". Glazy will automatically calculate the new recipe for you!

Glazy Patron Badge

Alchemist Badge

In order to show appreciation for ALL contributors, the Alchemist badge was added. This badge is shown when a user has uploaded 20 or more photos to Glazy. Photos are essential to understanding what a recipe looks like, as well as to compare differences between materials, preparation, and firing types.
