Adding Brushing Medium?

Recommended Posts

Is there an easy way to make dipping glazes easier to brush on?  Friend needs to add a band of glaze to the edge of plates and only has glazes mixed to dip.  How much glycerin  should she add?  Or is there something else she could add?

First make a gum solution with 2 tablespoons CMC gum to a gallon of hot water. If you have some, also add 1 tablespoon Vee-Gum-T. Let it sit overnight, then blend till smooth. When making the glaze, substitute up to 1/3 of the water with gum solution. To alter an existing glaze, you'll need make the gum solution really thick before adding to the glaze, so increase the amounts of CMC and VGT.

The CMC soln. will keep so if you don't want to alter Neil's recipe just mix it up with a lot less water, decant some of hte glaze in question, add some of the gunk , stir madly, and test the ease of application , alter as needed.

RIght only ever make small quantities so haven't experienced the bacterial growth.

Wall paper paste,is it still around?, do the same as CMC etc?

 

Not sure about the wall paper past.

 

The gum will degrade even once it's in a glaze. Sometimes this happens within just a few days- you'll notice it being more watery than before. Commercial glazes have a biocide in them to preserve them.

I've used wallpaper paste to try to stop glazes settling out.  Sometimes works, sometimes doesn't.  Worth a try as it's easier to buy locally than CMC.

Epsom Salts is what you need to stop your glazes settling.

For CMC look in your nearest supermarket - often sold as *Tylose* in the home-baking section, (it's used in cake icing).

And copper carb as opposed to bleach? Why is this?

does the copper content not effect your glazes? (more specifically whites and clears)  i know it's a tiny amount in relation to the gallon of water, but still... 

 

i keep a jug of thick CMC solution (150g CMC/1gal H20) and gas kiln wash with CMC and macaloid in it - since both don't tend to be used very quickly they end up getting funky depending on the weather/time of year.  i usually just splash some bleach in the kiln wash, and yes it is not a good long-term fix.  the CMC solution i just leave as-is, it would be nice to be able to cut down on the funk that develops in both buckets.
