Compatibility of Hadar's Metal Clays
Recently I have been getting a lot of questions about firing different clays together. For your convenience, I have prepared a compatibility chart which shows possible combinations of One-fire clays and their firing schedules. You can also access this document by clicking on "Compatibility of Hadar's Metal Clays" in the right-hand pane of this blog. Please let me know if you have questions about this chart or about other combinations.

Enameling on Bronze
This post is intended for people who enamel or wish to enamel on metal clay. Bronze is considered hard to enamel. One thing that happens repeatedly, for example, is that the enamel flakes off. This can happen right away (which can be dangerous if you are enameling with a torch), or it can happen over time. The enamel on the piece in the photo below flaked off over a period of a few months. Every once in a while I saw that another piece was missing. However, there is one c

Coming Soon! Hadar's Templates™ for Metal Clay
In a couple of weeks, a new line of plastic templates for metal clay will be available on my store. The initial release will consist of five templates. I designed these for my upcoming enameling workshops, but they can be used for any other application.

New Metal Clay Techniques and Upcoming Workshops
In the never-ending pursuit of hollow forms, I've been working over the past year on a new way of creating them. In fact, this way is the opposite of any hollow-form technique I've been using so far. Instead of building up the forms from layers of wet clay, I treat dried chunks of clay as if they were rocks or chunks of wood and carve the forms into them. Carving may be a misnomer, since this term is usually conceived as surface decoration. In this case the carving is structu
