Thanks!!! I learned sooo much! Greetings from Germany, Thomas

[@PotterybyKent]

Great to hear!

Thank you for the video, there's a lot of effort evident. Could you demonstrate how you measure the material thickness after casting? 👍

[@PotterybyKent]

The thickness of the clay in the handle? Here it is cast solid so there isn't anything to measure. If you mean for a pot, that is determined through trial and error as it depends on your molds and clay body. But you can measure a freshly made pot and apply your clay shrinkage factor to get the final thickness.

[@O.t06]

@@PotterybyKent Thank you for your response. Could you show the thickness of a freshly made pot in your new video? Thanks!

[@PotterybyKent]

You can see it in this one where I trim the slip well off the pot while in the mold. It's a few mm

[@kbsorrells]

These look great Kent. Scoring (roughing it up) the ends of the handle and attachment area on the mug will make a stronger bond.

[@PotterybyKent]

@kbsorrells yes as I mention in the video you can also score in addition to slip. However with slip cast pieces (and correct drying) it likely isn't needed. And indeed I just pulled a bunch from my kiln and they are all great.

I've used TPU to make molds for my plaster, and they worked decently well. Just be aware of the general drawbacks with TPU.

[@PotterybyKent]

Thanks for sharing. Surface finish seems like a major drawback since it eventually transfers into the pot.

[@ingegerdandersson6963]

If you wanted the handle solid why did you drain it? Wouldn’t it be better to let all of it try?

[@PotterybyKent]

Mostly because I was curious if it was solid at that point. Draining probably isn't required, but when it is demolded it is nice not to have very wet slip dripping off the end. (And you can't wait too ling otherwise it is too dry).
