Throwing a Lid Off the Hump

An easy in and out this morning...
I had posted a video a few weeks back showing how I'm currently making my lids by throwing off the hump, but I never got around to showing how the lids were trimmed up.
Here's a full clip showing the whole process...



The background music is, "I'm Beginning to See the Light" by Jay McShann. Love his magic fingers.

Throwing Lids for Canisters

I've been taking up some loose time this week with filling inventories for November. My kiln blew an element last week and now I'm passing time until the replacement part arrives. I've been throwing canisters for my local farmers markets.

So... this post is about lids.

I know a lot of potters hate throwing lids, I hear professionals and students alike grump their way through this chore. I've been lucky, I've really enjoyed developing my approach to throwing this type of lid. It's taken a few years and a few hundred lids to work out most of the kinks, but the time spent was well worth it.

My lids are made with heft, durability, and functionality in mind. They have got to stand up to at least a family's worth of use. They are truly a functional item that need be well crafted to fit to their companion well. Still, at the same time, I create these with an eye on my personal decorative athletics of strong curvilinear lines, clean tight surfaces juxtaposed with textures, and with a well formed knob on top.

The carved out concave in the center in the bottom of the lid is purely functional, it helps even out the drying of the form, decrease the weight, improve it's balance, and, well... I like it.

This is a deceptive shot. I'll usually throw a series of 7- 15 canisters in a sitting. All of the galleys are made to meet whatever my current predetermined inner diameter is. This is a ritual of studio covenience for me, this way I'm free to explore a body's form and the lid will essentally fall into place as it moves through the studio. This piece shown is almost 12 hours old. Shrinkage at this scale makes a huge difference... so pay attention to the "wet measurements" of those openings. Take notes and figure out your shrinkage scales of the clays you choose to use, it really pays off.

Let it dry to leather hard before trimming....


I throw a fresh trimming chuck to softly hold a green lid and slowly enlarge it as I work though a lid series.

This is the finished fit for a lid in a greenware canister. I don't approve of excessive slop in the play between the lid and galley. When I throw 15 canister bodies I throw 20- 25 lids and mix and match to fit the greenware.
