In Topic: Corroded Saggars

19 July 2016 - 08:46 PM

Marcia,

Do you have a special recipe or secrets for making your saggars?  I'm all ears...

 

I was just thinking aloud.... 1.  Do you think adding kyenite might prolong them?  

                                           2. Can you coat the inside of the saggar with ITC100 (or similar product) to make the internal wall less porous to  soda and volotile gasses?

                                           3. How many firing do you get from your saggars, anyway?

I ask because i'd love to make some.

If you soaked the loaf of bread in Sodium silicate and compressed the loaf with a 10- 20 ton press prior to placing it in the chamber, then fired it in an Argon environment, you would have silicon carbide.....a kiln shelf.

 

There is a great article Feb 2005 Science daily about making petrified wood using similar technique.   They placed wood in acid to breakdown the cellulose a bit, then soaked it in hot sodium silicate.  It went into an Argon oven and came out petrified.    So you could make a kiln out of wood if you wanted to..

In Topic: How Much Granular Manganese Dioxide?

17 July 2016 - 08:03 PM

I have used basalt granules instead of manganese to speckle my white clay body. i have used 20-40 mesh grains in a concentration between 2 - 4 %. It is not toxic and gives a nice cookie and cream appearance.... just a thought.  It also doesn't play too badly with any glazing.

wrens like to fill up any cavities that might entice other birds to move in too close to the wrens.  and their babies return to the house for some time after they begin to fly.  yesterday, the mother scolded my dog for walking into her yard.  

 

 

Years ago we had a pair of wrens claim our enclosed atrium.  We left a small upper window open.  The window had no screen.  So once the nest was made, we did not close the window until all the wrens left the nest an didn't return at night... The music was great. They sang as we ate breakfast.  Watering the atrium plants was not so easy.

 

  The nest was in an old discarded pot.

If you look at Community Challenge #5.  You can see the orange I came up with by adding Rutile to Amaco Dynasty red glaze ( cone 6.)
