In Topic: Question About How Cold Bisque Can Get In Below Zero Temps

01 February 2016 - 01:51 PM

I have had the same discussion with my clay club up here is Washington.  We concluded that the question is about how porous your work is when it is completed.  If fully vitrified and non-porous (so some extent all ceramic is porous) the better it will survive freezing temps.  It all has to do with the moisture that is trapped in the ceramic.  When ice is formed in these areas it will crack the ceramic.

 

Not sure testing in a freezer would work, because it needs all the environment variables present in something outdoors.


In Topic: Removing Unwanted Wax Resist

I can usualy get the wax off by scraping with the edge of a metal rib, you know the one that come in every beginner kit.  Make sure you scrape deep enough to get all the wax which will mean you are digging some of teh clay body away as well.  I have never burnt it off, but I am sure that is a good route as well, just costs for time and $$.


In Topic: Signature Stamps

19 March 2015 - 04:17 PM

What about potters from generations past that have not signed their pots in any way. I understand Warren McKenzie does not sign his pots.  Does this make it any less desirable?  I am not sure.  I choose to stamp my work, with a stamp I made myself.  It fits well within my aesthetic and it has never been a question.  When I am gone, or even while I am still here, I am not sure it matters that people know who made my pot.  They like it or not, they choose to use it or display it, or even toss it out....

I make my stamps out of porcelain that I carve myself and bisque fire.  Works well.
