In Topic: Qotw: Are There Redundant Things In Your Studio?

Today, 11:32 AM

 I can relate to that age in place-I did the 50 year roof (never doing that again) 25 year exterior paint(never doing that again)  a few years ago

Next are the shower grab bars . I'm not yet middle 60s but am thinking ahead.


Those shower grab bars and bathroom remodel went in about 7 years ago now.  New furnace about 5 years ago. New kitchen JUST went in and finished 3 weeks ago (needed it... last done in 1977).  Cedar clapboard siding is in process (contractors are here today).  New 50 year roof next year.


I'm 67 1/2......... time flies when you are having fun.





In Topic: Stoneware Limit Study

Today, 10:27 AM


One of the assumptions about stoneware clay, was that all the clay particles melted to form a vitreous body.



Actually..... no.  I don't think that ever was the assumption by folks that are "into" this stuff.


Stoneware clay is more like fiberglass cloth with fiberglass resin.  The crystalline materials (cloth) are bound together with the glassy phase (resin). 


The fact that it is NOT fully vitreous (which would basically be glass) is the reason that no one has ever been able to develop a computer model for predicting the performance of a clay body for such stuff as CTE.

I have some under table clay that has been there for 30 years-thinks its hard yet??

My next move will be into an urn.

If I ever move I'll be done with clay.43 years in same studio


I have some of that "under table clay" also..... and probably at the 30 year level also.  ;)  Really plastic and not able to make anymore due to raw materials sources being gone (my kingdom for Pine Lake Fireclay and PBX fireclay).  Some I take out every now and then to use.


Been in the same studio ....at 39 years here.


I can't conceive of moving my studio at this point.  If it has to happen due to age/health...... likely I'll be done with clay also, Mark.  At the moment my wife and I are getting the house and studio ready for the "age in place" phrase that is the current politically way of saying...... becoming OLD and staying put.





In Topic: Electric Vs Gas Firing - Surface Look - Clothes Or Skin

Yesterday, 06:36 PM


When I was in school the teachers never fired the kilns. The students were responsible for all firings. It's an important part of the ceramic process, and should be learned.



Our undergrad majors are required as a specific part of the curriculum to learn to fire both electric and gas kilns.  One full 3 credit course is devoted to that aspect called "Kilns: Practicum".  They handle and process probably 90% of the department's overall production including the Community Education classes work.

One big reason you don't see many folks firing cone 9-10 electric oxidation is that A.) it tends to kill standard type elements faster  B.) most "hobby type" (hex type) electic kilns are quite underinsulated and C.)  electric costs are high compared to gas costs (in part because of the poor insulation).


Better made electric kilns like the Fredrickson front loaders go to 9 nicely and rival a commercial gas kiln for insulation and cooling rates.  We have a Fredrickson front loader at the college (amongst a Skutt hex and an L+L square)... and some students do high fire electric oxidation in it.
