Les,
If you add a binder to your glaze it should not dust off. I personally
add 1% of macaloid to all my glazes. CMC or bentonite might help also. Mia

My glaze tends to brush off the pot after it has dried . I was wondering
what and how much of some additive I could add that would harden the glaze
to the pot and make it more manageable to work with. (maybe starch - how
much)
Thanks in advance.

You can use diluted starch in water. Say 1-2 tablespoons in a cup of water.
This works for majolica and then the over glazing.
Good luck,
Marcia

I used carro syrup (sp??) in the past, then my glazes tended to smell after
a while. But it did harden them up, like a rock. = )

Some things you can use...
Hairspray... just spray it on
CMC gum... mix with water and mix into the bucket of glaze
Syrup... use like gum (not recommend if the glaze is going to sit for a
while... it will ferment)
There are many things to use to give a hard glaze surface... you will surly
get many suggestions.

Leslie,
You can add 1% cmc or veegum to your dry glaze. Be sure to sieve it. Some
people mix it with water and then add it to the glaze. I can't speak for
that as I have always done it dry . It definitely will make the glaze
surface stronger.

there are a number of things that you can use to accomplish this. The first
one might be the addition of bentonite or macaloid. You can add up to about
2% to your recipe without changing the results that you get.....usually!!!
Here again..test if you have questions. I have found that either of these
usually solves my problem..

Hello Les.
The best would be to reformulate the glaze to have more clay in it.
You may you also up to 2% CMC. It is not that easy. You start with
half% and go up. It is not easy because the glaze will dry slowly, you
might have or want to add another layer. It is a good solution, if you
do majolica to avoid mixing your painting solution with the background
as in this case you need it as it would be a paper.

An old Majolica painter's trick is to add 1 dessert spoon of dissolved
sugar per gallon to the glaze: the sugar migrates to the surface on
drying giving a crisp surface on which to paint. Could help handling
problems as well.

Hi Les,
First thing to do is replace ant kaolin with ball clay but do it by the
molecular formula - that way you get more clay in the recipe (cause the is
less Al2O3 in Ball clay so you need more of it) and ball clay gives a
harder dry surface. If that is not good enough add some bentonite - that
gives an even tougher surface. If that doesn't make the surface stable
enough drop the benyonite and then try the solubles.
Solubles can be a pain in the --- if they are organic they rot, if they are
salts they can crystalize and migrate to rims adding more melting. Whatever
you do don't use any more then you have to.
