FastFire BRONZclay Success!

After feeling a bit "burned" by base metal clays a few months ago, I went ahead and tried a new brand on the recommendation of jewelry artist Evelyn Pelati.  I went with FastFire BRONZclay by Metal Adventure and was happy with the results for a variety of reasons.  Here are a few...

To begin with the obvious, it fires fast.  It takes an hour to ramp and an hour to fire.  It is a one phase fire, so set the kiln and forget it.  I was looking for a base metal clay to use with multiple classes, so I do not always have the luxury of being able to run a multi-phase firing during my teaching schedule.  This allows me to not have to return to run a firing on my own time. 

There is the other obvious of the price, with bronze clays being around 30 cents a gram and silver clays being more than $2 a gram, it is the most economical, especially for introducing it to a large class.

The firing directions are clear and easy, particularly if this is your first attempt at base metal clays.  The descriptions of what you will find out of the kiln and what that means for your firing temperatures are also clear.  I was able to figure out my firing schedule after just two test fires, though I have had to make adjustments based on running a whole class worth of pieces at a time.

I have also been able to successfully fire in a ceramic firing vessel.  Since I am flip-flopping between silver and bronze, depending on the class, I am running multiple firings a day.  When you fire in a steel pan there is a black flake sort of fire scale that needs to be vacuumed from the kiln after your firings.  With a ceramic vessel, there is no evidence of the base metal firing.

Last, the workability of the clay has been great.  It has a silky flexibility that makes it great for draping and forgiving for students just learning to work with it.  When it dries, it is easy to reconstitute and continue working.

These were a couple of quick test pieces where the clay was rolled into scratch foam designs and run through the firing.  The bronze has a warm gold hue and nice weight once fully sintered.  

Transformed

Last week's post referenced Ernst Haeckel's Art Forms in Nature, which is an intriguing look at biological forms.  Haeckel asked the viewer to look more closely at fantastical biological forms that were often overlooked, there by transforming preconceived notions of what certain things ought to look like.  For this piece, I found myself drawn in by that very same idea of seeing something otherwise forgotten.  While out collecting pods for more pieces, I grabbed a couple of small mushrooms whose texture was irresistible.  As they dried, they curled in on themselves, forming their own sort of cocoon.  I continued using the metal clay slip-dipping method, but was met with very different results.  To begin with, mushrooms are very spongey.  Unlike the paper thin pods that quickly absorbed and then built up the metal clay layers, there seemed to be no end to the amount of metal clay slip the mushrooms would absorb.  Next, continuing to wet the mushrooms with paste began to smell a little like I was raising pigs in my studio.  I began with three mushrooms, but ended up with just one piece.  The first catastrophe occurred before firing as I tried to drill into the delicate form in order to create a channel for the chain, it split into pieces that were not worth repairing.  I was able to soak the mushroom in water and remove the majority of the paste in order to recycle the metal clay for future use.  As you can see below, two mushroom forms made it into the kiln, the smaller of the two with a fine silver wire running through it in order to build a bail after it was fired and avoid trying to drill my way into a second disaster.  After firing, and tumbling, I began trying to manipulate the wire and realized the smaller form was too soft and the spongey mushroom had not sintered properly.  I bent the form back and forth until it cracked and got a look inside of the incomplete layers.  The third piece in this series held up.  A little larger, with deeper textured grooves to hold the paste, this form seems to be the right balance of paste and organic matter.  The center is set with a marquise cut 4 mm green CZ, mimicking the oblong form.  The beautiful texture is further pronounced by a patina of alcohol inks in green and red, a subtle nod to the fall day this form was discovered.
