Stoneware Clay With Low Fire Glaze

[eoteceramics]

Hhi everyone , I hope someone can help with this question.

 

I am making pieces for the garden and so using stoneware and high bisque firing.

However the glazes I want to use are firing around 1040, really bright colours.

 

Will  the fact that its an earthenware glaze on stoneware be a problem, ie will it fire to the correct colour?

 

Thanks Julia

Not sure if what you mean by "high bisque firing" means firing the clay to maturity? If that is what you mean then it is going to be a pain glazing the pots. If the clay is no longer porous (or mostly non porous) it’s tricky getting an even smooth layer of glaze to stick to the pot. If you do go this route then warming the pots up to around 100 celsius and using slightly thicker glaze helps. If you can spray your glaze this makes it easier too. 

 

As far as using low fire glazes on mid or high fire clay, that is fine (and low firing). It’s more the colour of the clay that makes a difference. What kinds of bright colours are you looking for that you can’t find for midrange? Better to use mid-range glazes on mid-range clay then you don't have the porosity issues.
