In Topic: applying iron oxide to greenware

Today, 09:21 AM

Thanks for all the info, just one question not yet answered for me.
If I spray oxide on to bisque and want to refire to fix it before glazing - what temperature will fix it?
In the future I think I'll spray on to greenware, but currently I have a few pieces already bisqued & don't want the oxide to move at all.

In Topic: Glaze Stoneware Or Earthenware?

if this works out like the usual Murphy's law, you will have a great glaze that you want to duplicate and use all your life and will not know anything about it.   :)

How right you were Old Lady - I managed to contact the girl who sold me the glaze, in the Philippines who told me it was indeed earthenware glaze - yay! See picture below of a test piece I just dunked in the turquoise matt and fired! I love it - can't wait to try it in a more purposeful way. I have asked if the recipe is her secret, or available to be shared. Let's see what she replies.Attached File  image.jpg   6.04KB   0 downloads

I also struggle with glazing pieces with holes (some of my favourite forms!) - can't pour, as the glaze dribbles through the holes, then runs and collects in thick drips! Similarly dipping.

 
I would still dip and make a quick dip, virtually 0 count hold.  This should minimize the glaze thickness.  IF it needs to be thicker than dip a second time.   Any thick drips are easly scrapped to the same thickness once dry.  Even if you scrapped all the way to the surface to remove the thick drips,  you could quickly patch those small areas by brush and still wind up with a more uniform glaze that looks better when dipped than brushed.

Tried the quick dip, then tidied up when dry. Kiln cooling now - fingers crossed!

I use an app called 'resize image' as it is simple and you can choose the file size you want to output while keeping the same aspect ratio


Thanks for this one - dead easy, free and did the job!

Thanks Ajay - in the meantime, I also found this:-

However if gum powder is mixed with other dry ingredients before adding them to the water it can be done (often 0.5-1.5%). A much more effective method is to boil water, add about 25-30 grams of powdered gum per litre and mix vigorously with a mechanical mixer. Normally this mixture is added during mixing to replace part of the water however I have found that for brushing it should be used to makeup the entire water complement. There is room to use 40 grams per liter if needed.

It sounds as if there's a wide margin for error here, so I can't go far wrong. Will definitely try some for pieces I just can't manage to dip / pour, but will test first to see how the different quantities affect the 'brushability'.
