In Topic: What Type Of Glaze Is This?

16 November 2014 - 12:15 PM

Another way to achieve the look of the black lines on the flowers is to put black underglaze on the pieces after they are bisque fired, then wipe it off with a damp sponge, leaving black residue in the lines - then glaze over that. The black areas remain much darker than the rest.


In Topic: Thinking Of Trying Porcelain

If your stoneware and porcelain mature at the same temperature, and you blend them sufficiently, there should be no problem mixing them together. If you overfire it you may get bloating and slumping, but that is true of many clays.

 

Why do you need to thin the glazes more for porcelain? Most places that use both clay bodies use the same glazes for both bodies. Translucent glazes will tend to look lighter and brighter on porcelain.

 

I really love using porcelain. Good luck with it!


In Topic: An "office" Kiln

Many years ago (late 1970's I think) there was a pottery studio on one of the upper floors of Riverside Church (around 120th St.) in Manhattan. I have no idea if they still give classes there. 

 

In the same area, Teacher's College at Columbia University also had a few ceramics classes open to the general community. 

 

This is very old information, but worth checking out. I hope you find something!

Glad to see you back!


In Topic: Using Propane Torch For Glazing

23 February 2014 - 08:39 PM

Another problem with using a propane torch to fire something is uneven heating. The spots where the torch hits can get very hot, but other parts of the piece are considerably cooler.  The thermo-shock between the hot and cool spots are very likely to lead to cracking as the clay goes through major changes when the chemically bound water in the clay body is released and when the quartz in the ware changes composition when heated.

If you are using the torch to heat a chamber with the ware inside (like a small kiln) so that the atmosphere and bricks are heated as well,  that is an entirely different situation and may work. 

As always, your situation may vary. Test, test, test.
