Question about slip

The commercial clay menders may be applied to dry greenware and don't crack
while they (menders) are drying. I want to paint slip all over a piece to
smooth it out more, but the piece is dry. I've heard that if you mix vinegar
with the slip, it behaves similarly to a clay mender. Does anyone know if this
works? Would I be able to paint a whole slip coating onto dry clay if the slip
is vinegared?

I'd appreciate any insight anyone may be able to give.

Your easiest way would be to make sure that your pot is bone dry and dip it
into the slip. Make sure you have enough slip to dip the pot in one go.
This way you will get an even and smooth coating

Do I need to add the vinegar?

Thanks for your reply.

I have used a vinegar and slip mix to mend, but it was only a small
piece.the vinegar makes the slip go thicker so i do not know about
"painting" a piece with this.if as the other person suggested you dip
the piece in slip i would first dip the piece in water so the slip
will grab more evenly.Maybe you have a piece of waste that you could
try it on first.Let us know how you get on.

Should have asked this question sooner

What is your slip recipe?

I copied this reactive slip recipe out of Salt-Glaze Ceramics by Rosemary
Cochrane

Gerstley Borate 7
Alkaline frit 9
Silica 20
China clay 40

I added 1% copper oxide as I am looking for an oxidised green.

The slip was made up to the thickness of milk

I have applied this to some green ware and trials are in the kiln at the
moment. Beause of the amount of china clay it went on very smoothly when
the ware was dipped.

The other thought is that if yore looking for a smooth surface have you
thought of burnisheing or terra siligata?

Thanks to all who replied. This piece is very intricately shaped, turned, and
twisted into a sort of coral-like sculpture.

I put my Balcones White clay (^8-10) into the blender with water. I use the
Balcones White, but raku-fire it. I would like to just brush the water-clay
mixture on top of it. I think I'll just put in a generous amount of vinegar,
too and see what happens. "See what happens" is one of my art watch words...
as long as it's not dangerous.

Linda, I am rather new to this art form but a member of my class swears
by vinegar and slip to mend things with no cracks.

Could you by chance find out what the mixture is for this "glue"?

We had a really pleasant repair attempt work in our studio. Someone's slab
plate had cracked on the edge in the bisque firing (a crack going from the
rim down to the bottom of the plate). We fire to cone6 and our glazes and
clays are very forgiving. I recommended that she try glazing her piece,
taking a thin piece of clay (she made a star so it became decorative),
covering the crack with this and then glazing the green clay "bandage". It
worked beautifully. I program software and frequently have to come up with
unusual solutions. This however is the only "idea" that I am really proud
of having worked.

vinegar and dry clay powder (same as you use) plus a bit of golden syrup,
just a tad, don't know why it makes the difference but it does..... Oh yeah
use on green ware (i have tried it on bisque, and it worked for me but i
wouldn't reccommend it...)
