In Topic: Mason Stains As A Wash

15 September 2014 - 01:45 PM

I have use my clay body (B-mix in this instance) and Mason stain thinned to a slip to highlight detail in bisque fired pieces, painted on underglaze (Amaco Velvets) to color certain elements, and covered the whole with clear glaze and fired them.   I also make and uses washes on bisque similarly.



In Topic: What Is The Most Challenging Aspect Of Working With Clay?

Patience!  As a part-timer, I rarely have the opportunity to make a large number of similar objects and wait for them to dry to be suitable for bisque, so I am always rushing things through to fill a kiln, sometimes with predictable missteps and losses. Then after firing a load of bisque, the glazing well, versus glazing quickly, dilemma arises.  For a time, I tried going the once fire route, but that has its own hazards and issues.



In Topic: Kiln Blankets?

I didn't see a temperature rating, but the description sounded odd for a product made to fire clay beads.  I was reading the reviews and noticed that it is for polymer metal clay. Wrong kind of clay, the blanket is for precious metal clay.  That's the trouble with calling things clay that are not silica based clay; too easy to misunderstand for the less experienced. 


It looks like the PMC fires to 1,650 F.  Some earth clay products also fire to 1,650 F. somewhere around Cone 010, but typically earth clay fires higher than that.  If you were to glaze and fire beads using the blanket I believe you might end up melting the blanket and beads together.

wow, john!  don't forget windows.  


tom, heated floors are the very best!


14 years without windows sounds like a sentence!  what did you do! :)

Oh yes, so many years in the basement without windows, I didn't even think of that. Working without windows keeps you focused on the work at hand.  My new space has windows looking out into a forest, but the windows are under a deck.  I am hoping having the furnace in the basement will keep the place above freezing, if not in the 50-60s in the winter like my basement now.



In Topic: Shinsha Glaze

01 September 2014 - 08:14 AM

I found a link to a blog that has a recipe for Shinsha glaze.  It is a reduction glaze, does include copper carbonate in the ingredients, but no gold (that seemed unlikely to be BTW.)  It reads like a tough glaze to fire properly.


The picture looked like a copper red with some thinning at the rim making the white, and possibly another copper containing glaze producing the green down low and inside.  I am no glaze expert, but these are my observations. 


Some Google research shows a number of pots for sale with Shinsha glaze.  Most have the red/cinnabar color and blushes of green, but much less pronounced than your example, but those may be on a darker clay body.
