In Topic: Newbie High-Fire Glaze Question

Yesterday, 06:07 PM

Your glaze needs to match the temperature at which you are going to fire.  Glaze fire at cone 9/10; use cone 9/10 glazes.  Glaze fire at cone 6; use cone 6 glazes. 

 

That said, some glazes can be used at multiple temperatures (although they may not look the same or have the same glossy/semi-glossy/matte finish).  You might want to make some test tiles and glaze them with your cone 6 glazes and see how they work at cone 9/10.  Or, dip your test time in the cone 9 glaze and then dip in the cone 6 (but only top quarter) to see how they work together.  Be sure to make a small disk/bowl to put the test tiles in so you catch any glaze runs and get glaze on kiln shelves. 


In Topic: Throwing Thickness

A thin walled drinking vessel will dissipate the heat of the beverage faster . . . for a yunomi, that could make for hot hands.  A thicker walled vessel will retain heat.  I also like my bowls/rims a bit thick so they do no chip easily . . . especially mixing and serving bowls where serving utensils make constant contact with the vessel.  It becomes a matter of functionality and aesthetics and how you balance the two. 


In Topic: Respirators, Beards, And Mixing Glazes

29 July 2015 - 06:58 PM

As John B. stated, there is no easy answer to this.  A respirator protects our lungs from dust that is inhaled.  But that same dust in the air can settle on your clothing -- or your exposed facial hair -- and possibly inhaled after you've removed your respirator.  So, you need to employ a range of tools -- including a respirator -- and techniques -- storing, measuring, mixing, etc. -- that minimize airborne particles as much as possible.  Think about how you remove dust from your clothing after mixing glazes.  Reducing risk needs a holistic approach, not reliance on one single safety device. 

 

Absent working in a clean room, we need to find comfort levels in how we reduce the risk of airborne particles.  Wearing a good fitted respirator is a great start . . . but it is only a start.  If you are doing this for an hour once every three months, the risk is different than if you were doing  this every day, all day long.

Obviously, we need Congress to enact the "No Potter Left Behind Act".
