For the Potters: Ceramic Arts Daily has a new downloadable PDF file on making glazes. Here’s the link. I have dabbled in this from time to time and it is always rewarding to tweak a recipe and come up with something that nobody else has in their inventory.
I also found this on the web: it’s on Pinterest (a site that has for the most part baffled me). It’s full of free jewelry design tutorials. If there is some technique that has been baffling to you, there might be something on that board to clarify it. Have fun!
