Am I applying bat wash correctly?


Recommended Posts

Hi all,

Wondering if I'm applying my bat wash wrong, but when it's dry it transfers easily. See photo. This was just a one thin layer that had weeks to dry. Was going to do a second layer but now not so sure.

I'm using a commercial wash that came with the kiln. Worried it will stick to my pots :/

If it hasn't been fired on yet then yes it can be dusty. 

It would just be a guess but the least expensive materials to use in a kiln/ batt wash would be kaolin and silica so if companies are trying to save money with the wash they supply they will load the wash up with that and skimp on alumina hydrate. There is a link below discussing kiln/batt wash with some tried and true recipes (it's towards the end of the link). Also, I would suggest wiping it back from the edge about 1 cm and wipe off any drips from the side of the shelf.

I would make my own wash and remove with a wet sponge  before firing any commercial wash as it usually poor quality.

Speaking of quailty wash I noticed on the Advancer shelve (kiln shelve.com ) site they use the same formula as I posted years ago

1/2 alumina hydrate

1/4 epk

1/4 calcined EPK or (glowmax)
