Transparent glaze problems

Recommended Posts

Hi,

 

I have a problem with transparent glaze which needs quite thin application.

 

I was testing it (dipping) on unfired pieces and it turned ok. They accepted exactly right amount of glaze, just perfect, eved overdips evened out great, no blisters, no pinholes, no problems at all.

Then for "the real pieces" ;) I tried dipping the bisque pieces and it did not work. The bisque pieces accepted too much glaze, I had to wash them and pour only the inside (it is easier to control the thickness I think) then I sprayed the outside. Even slightly wet pieces (from washing) accepted to much glaze. I also tried diluting the glaze a little, which did not help much...

Pieces came out partially ok, about 30% ok, others had too much glaze. Just for the record I am not counting to 5, I pour the glaze inside the cup and immediatelly pour it out.

I am talking cups, jars and teapots here.

 

My question is should I dilute the glaze even more?

I would LOVE to dip, but the pieces are to fragile to go unbisque, and I am worried to ruin the underglaze... it is so so time consuming to do both (dip inside and spray outside)

I was watching youtube (Simon Leach glazing teapots) and drooling :)

 

What can I do, any suggestions?

thanks in advance!

I would add more water to this glaze in very small steps till it was the perfect thickness to cover the way you want.

you get it to thin let it settle and pour off the water on top to thicken again.

Glaze can be thinned or thickened in this way.

 

The only other ways (to apply thin) are to spray or you can also wet the bisque but thats hard to repeat right every time.

 

If this is low fire they have brushing glazes but my experience is near zero in this cone 06 world.

I totally agree, I was having the same problems with a clear matt glaze I was using. The pieces all came out with that sugar frosting white drip and I just kept adding water till I got it right. Good luck T

If your glaze is over-flocculated, adding water will not help. If this is the problem, mix in a tiny bit of Darvan. This will "thin" the glaze without adding more liquid. If you think that is the problem, you might try adding a couple drops of Darvan to a cup of glaze and see what happens.
