In Topic: Bisque Fired Underglaze Bleeding Under Transparent Glaze?

02 March 2017 - 07:38 PM

Might your underglaze not be applied evenly?  If so,  the streaking may be caused by uneven layers of underglaze.  Remember to apply more than one layer of underglaze (painted on in various directions).


In Topic: Does Anyone Use Continental Clay As A Supplier?

Continental's mid-fire white  (cone 4-7) and mid-range oxidation (cone 4-8) bodies are the main clays used at our local art center.  One member also uses the High-fire white (6-10) and all work well with our oxidation firings at cone 5.  We use a variety of Continental glazes and also some 'scratch' glazes that we mix ourselves.  Really have not had any problems with crazing. Continental used to have the shrinkage info right in their catalogs along with the clay descriptions but not now - I miss the paper catalogs - they were so convenient and held a wealth of info.   Continental is very helpful on the phone so I bet a call to them will yield answers to your questions.  They do have a new mini-catalog devoted to just the clays they offer - can't find mine at the moment - but perhaps that info is included in the new printing.  Personally  am happy to have Continental close as it is staffed by very knowledgeable potters - you have a question or a problem - they will have someone on staff who will help you solve the problem.

 

Personally I prefer the mid-range brown for wheel work, as I like its 'tooth'.  I am not one for white clay or porcelain, as to me they are too slimy on the wheel. But if you are one who uses underglazes, I like its white background behind the underglazes, better that the brown background.  But that is personal preference - for my kid's classes, I prefer  white for handbuilding (due to underglaze use), and brown on the wheel.  Another teacher prefers white for all.  Go figure...

 

Continental has a variety of clay - and a wealth of info.  Have fun in your new studio!

OMG!!  That wheel brings back memories!  It looks just like the wheel I started on at our local art center (close to 40 years ago) .  The wheel sits on a table with the  rope almost hanging to the floor, and then to engage the motor to turn the wheel, you step on the hanging board at the end of the rope. It makes for a very primitive electric wheel.  There were 6 of us in my first class with 2 'wheels' - we took turns (in more ways than 1).  We did learn to make pots.  Despite the basic primitive wheel, I fell in love with clay and throwing.  Several years later I decided to take a 'real wheel class' at Edina Art Center in the Twin Cities, an hour drive each way.  When I called to register, I asked the gal who was registering me for class "how many people will I have to share a wheel with?" and after a long pause she replied "each student has their own wheel to use".  My response was '"SIGN ME UP" and I made that drive for classes for 10 years - great teachers there!  Now i finally have my own wheel and love to share the knowledge that other potters have so generously shared.

 

You do not mention where you are from, but you can replace the motor and belts easily (try a hardware store or farm supply) and do some of those safety measures that Neil measures. Once you begin having fun with it, you don't want to loose any work time because a finger or such got caught in the mechanics of the wheel.

 

The wheel may be bare bones (in more ways than one) but it is a wheel....and a step towards a bigger and better wheel.  Good luck and happy potting!!

My test sample turned out as I hoped, a soft semi matt yellow/gold with speckled iron showing thru.  The color I was hoping for but my small bowl is ugly so I am t proud to show it here - will also have to figure out how to post pictures.  I have a larger batch mixed and hope to glaze and fire on the weekend and then will post a picture.  That was my success in the kiln - and luckily partly because I got what I was hoping for.  Dumbest thing I've done lately ....6 identical small bowls with new test glazes fired in the kiln.  I marked each with a number on the bottom...with wax..then fired...wax burned off ..glazes matured...2 successes..4 failures. Now which of the 5 remaining glaze tests is the other glaze success?  So I have 5 more tests to put into my next firing.  I love clay!!
