My dentist gave me a curved syringe & I use that to force slip into hard to reach areas.

Great idea.

Great video, love how your glasses click together in the middle. Some of my clay bodies if I rub them with a wet sponge it brings out the grog when they are dry.

John Britt said...

Porcelain is different from stoneware.

Stoneware you have to just a stick to push the clay down. Like you say with a sponge, the grog come out. It takes out the fine particles and reveals the grog.

those are the niftiest glasses i've ever seen. Britt, you're the coolest!

Patsi Minnes from British Columbia sent them to me in a merciful attempt to get me out of my AARP downward spiral. The one where you have food bits on your glasses that hang around your neck with a moldy old cord.

My question is what about the content of the video? ....Guess I should just try dressing better ?

Emily Reason said...

i thought you were demonstrating your new glasses

John Britt said...

Funny, Guess the next video will be my new diapers.

Emily Reason said...

just kidding. good content, i'll have to try that. I smooth over small cracks with the edge of my needle tool at bone dry. it usually works. if the crack is significant, i use vinegar slip that is not too moist, similar to deflocculated slip I 'reckon?

Emily Reason said...

diaper, I wouln't put it past you ;)

John Britt said...

Try the deflocculated slip. Way better than vinegar.

Want to see my infected toe!?

John,

Two questions. How dry can your porcelain be, before this method no longer fixes the cracks? Also, what's your favorite method of making deflocculated slip.

John Britt said...

Bill, they can be bone dry. (and those were.)

I make the deflocculated slip by taking throwing slip and then adding dry trimming scraps until thick. Then a couple of drops of Darvan 811. That thins it, then more dry trimming scraps. Then a bit more 811. Then dry trimming scraps. Then it is done.

I am tired now! Nap time for grandpa!
