What causes Pinholing in glazes

Answered By: William Hernandez Date: created: Jul 11 2021

Perhaps the most common of all glaze defects, pinholes are tiny holes in the glaze surface which penetrate all the way through to the body. They are caused by gases escaping from the clay body during the firing cycle, after originating from tiny pieces of organic matter, such as charcoal, which is present in the clay.

Answered By: Carter Taylor Date: created: Apr 11 2022

Fluid melt glazes, or those having high surface tension at melt stage, can blister on firing if applied too thick. Glazes having sufficient clay to produce excessive shrinkage on drying will crack (and crawl during firing) if applied too thick. Fluid melt glazes will run off ware if applied too thick.

What does bentonite do in a glaze

Answered By: Thomas Parker Date: created: Jul 15 2021

Binder: Bentonite binds particles together in ceramic bodies to make them stronger in the green or dry state. Its minute particles fill voids between others to produce a more dense mass with more points of contact. Adding bentonite to glazes also imparts better dry strength and a harder and more durable surface.

How do you keep pinholes from glazing

Answered By: Oliver Thomas Date: created: Jun 25 2022

In addition, a rough surface exposes pore networks inside the body to larger volume ‘exit vents’ that produce pinholes in glazes. You can prevent this by using a finer body, smoothing the body surface in the leather hard state after trimming, or by applying a fine-grained slip.

Can I brush on a dipping glaze

Answered By: William Scott Date: created: Dec 17 2021

Yes, you can use dipping glazes for brushing with a few small adjustments. Since dipping glazes are already thin, you can’t make them thicker by simply adding gum or reducing them. Thickness is needed; otherwise, the glaze won’t properly brush on.
