1 Mug Survived - Great Morning!

15 January 2015 - 12:32 PM

I'm sure many of you will roll your eyes at my epiphany this morning.

 

I have been working under the impression that as time goes on I will get not just better and better but faster and faster. After cutting mug forms in half for weeks and getting my mugs where I wanted them I have settled into leisurely throwing my mugs in 15-20 minute increments.

 

Have they gotten better? Yeah sure but the time hasn't been changing. I mean not changing at all. 

 

So this week I have approached it with the goal of cutting it to 5 minutes centering to racking. Figured enough was enough and I should be able to throw 10 mugs an hour. The first couple of days I just tried to step it up and it didn't budge. All attempts resulted in a racked mug and all took right around 20 minutes. 

 

This morning I hit it with a clock next to the wheel and decided the time limit was 7 minutes, no exceptions. 1 mug made it to the rack. I was actually laughing by the end of my throwing session as it just seemed absurd as I tossed failed attempt after failed attempt into the slop bucket.

 

yeah, yeah I get it now. I have spent all this time training myself to throw a good 20 minute mug. Big whoop. Now I have to tear it all down and start over and build a great 5 minute mug. 

 

It's really not a speed thing, I love throwing but while fussing around with a form for 20 minutes might make it more detailed and that maybe would be considered a little better by some, I think in the end the form suffers because it is overworked and I suffer because I will end up not throwing to potential and my skills will be slow and mediocre. 

 

I learned this morning it's going to take some work for me to be able to cleanly open and pull a 5 1/2 inch mug in 2 pulls but the one on the rack gives me hope :-)  


Sealing Hump Molds

21 November 2014 - 01:53 PM

I have a dozen hump molds I made and use on a regular wheel. I have a designated wheel and rack for this process and carefully clean the area up between uses to avoid any contamination.  

 

My problem is that as I move the molds around between the rack and wheel and throw on it, some small bits of plaster and plaster dust is around the area at the end of my session. Its not a lot but I would like to reduce or eliminate if possible. This weekend I was going to thoroughly clean the molds again to make sure all loose plaster from the making process is truly gone.

 

The side rim and bottom seem to generate the plaster debris I'm talking about and neither of these surfaces need to be particularly absorbent as the clay doesn't sit on the these surfaces. I figured after that cleaning I would lightly sand and then coat these surfaces with something to make them less prone to flaking.

 

Fist off does anyone see a problem with this plan and does anyone have a suggestion of what to use to coat the side rim and bottom. I may from time to time hit the rim with the tip of a throwing tool so I don't want to use anything that would cause too much havoc should a piece of it end up in clay and get fired.

 

I was thinking of brushing on something like diluted Elmer's wood glue. I like the glue idea because it is less likely to flake as a powder if its hit with a metal throwing tool and if a small piece did find its way in I assume it would burn out fine.

 

Any input would be appreciated. Just started working with molds and followed the best practices outlined here on a CAD posted article.         


Brent Wheel Won't Stay Stopped

19 November 2014 - 12:09 PM

I have a Brent IE-X wheel that's about a year or so old and has seen really very limited use. Yesterday is developed a frustrating problem. When you stop the wheel with the foot peddle it stops for about a full second and then there is a little vibrating hum from the motor and the wheel starts slowly turning in somewhat of a jerky motion. If you press the foot peddle it then runs just fine but I can't come to a stop.

 

I checked the foot peddle pretty thoroughly and there is not any thing such as dried clay keeping it from coming to a stop and like I said it does stop, completely, for about a full count before starting that creeping forward motion.

 

Would appreciate any ideas?

Fast Drying Tiles

14 October 2014 - 03:58 PM

I will have a hundred or so tiles drying sandwiched between drywall made in several smaller batches spanning Mon AM (yesterday)-Wed PM (tomorrow night) I need to bisque them Friday and glaze Saturday. I have always left for a few days in drywall and then air dry for a few more to bone dry.

 

Any suggestions on drying them quickly without causing them to warp and/or crack? I was thinking sliding them to new drywall on Thursday and then Friday AM candling for several hours in the bisque firing.

 

I would appreciate any input. The tiles are 4x4x3/8.
