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

15 September 2014 - 06:32 PM

wish i had a small test kiln for glaze tests.  i know the base glaze is great but i want to try new colors for specific items.  the temptation to just put some colored stain in and glaze a pot or two at the same time as the test in a firing for a show is really hard to resist.  did it again today with tiny angels for christmas decorations.  if the colors are pale, that is all that matters.   i will know on thursday when i can open the big kiln.

thanks, terry.  concise i am not.  i just hope the reader can understand what i write.

 

the OP has several oxides and other chemicals, not mason stains.  oxides work and can be much stronger colors because mason adds things to make the stains look the correct color all the time.  in the plastic bag you purchase it in the color will look the same way it does on their printed chart, same way it will look in a clear glaze that is made commercially.  this is to make it easier for people not used to oxides.

 

if you ever noticed the color of raw cobalt oxide, it is black.  the color when fired is blue.  depending on the amount of oxide in the recipe, the % used, the color can be dark as navy blue or paler like the sky.  cobalt oxide is extremely strong and has to be mixed very well and sieved thoroughly so tiny specks of dark blue do not appear on the finished product.    

 

when you use mason stains to color slip you will find that some do not work as well as others even if you increase the % of stain.
