In Topic: Studio Clean Up Question ( Wheel Throwing )

21 April 2017 - 09:02 PM

On a side note ...
some people throw with lots of water and some people use less ... the main thing is not to let the water stand in puddles inside the pot or around the base ... sponge down your work area more often if you use lots of water ... work quickly.
I've seen good potters who work both ways ... granted you don't want to drown the pot ... but you also might enjoy the feel of a slick surface.

In Topic: Disappointing Glaze Firing - Help?

It sounds like your kiln milght have fired unevenly ... next time put a set of guide/witness cones on each layer of shelves.
Some electric kilns fire almost a Cone cooler on the bottom or top shelf.

I highly recommend the book "Clay, a studio handbook" by Vince Pitelka.
It addresses most pottery issues and has a hundred pages on glazing and firing.
It is worth every penny.

You are minutes away from Seagrove, NC ... home of more than a hundred potters!!
Drive down and talk to some ... kiln space is negotiable.

Welcome aboard!

 

As with most things in clay, these questions will get you a wide variety of answers ...

 

Yes, its a good idea to prop open the kiln lid on an unvented kiln to release vapor and fumes ... its good if you can, but not to panic if you cannot.

 

Heat and time are crucial elements of firing.  "Heatwork" is a combination of heat over time.

Fast firing gets you to a certain temperature quickly but firing more slowly gets you to the proper heatwork.

 

So if you are just running some bisque you need quickly it might be OK to just jam up the temp.

BUT ... if you are doing glaze firings or a series of tests, fast firing will not give you the best results.

Most likely glazes will be underfired and greenware pieces might not survive the shock.
