In Topic: Lets Do The Happy Dance

We all have to deal with water in our firings. Bisque is where most have the most disasters. Mechanical water, Atmospheric water, and chemical water are all possible culprits to cracks, blow ups and major disasters in a bisque fire. I always go slow until after 1100 F. as you have all sorts of things going on in the kiln up until that time. First the atmospheric water has to be driven out(assuming the pieces are bone dry), secondly the chemical water is released, and then organic matter, and finally the quartz goes into inversion. Best to fire slow til then.

 

Many people do not pay attention to water in glaze firings though. If your pieces have not dried sufficiently after glazing, especially on soft bisqueware, you may end up with crawling, pin holing and other glaze defects you would rather not have.


In Topic: Input On These Cups/handles

Over the years, I have put handles on mugs that were coils, thick carved and stamped coils, wheel thrown loops, extrusions from small and large extruders, press molded, and pulled. Depending on the mug personality, the handle needs to fit. I guess that is where being an artist comes to play. The craftsman repeats and is great at what he does, but when he starts making aesthetic decisions about what goes best with the form. . . . he is an artist.

Yeah, I can relate to the oven bit, as I sometimes will dry a cone pack in one. On the other end, don't try that in a microwave on full power! She really did not like the results of that.

Silicone Carbide as I understand it provides a local reduction of the glaze. Thus allowing the Copper red.

After the handle is attached and blended in, I use a damp finger to shape the curve into a pleasing movement off of the mug. I DO NOT handle the handle more than that as it will become to fussy and become misshapen or unnatural.
