Batt Wash

About

3404 Batt Wash
Specially blended mixture incorporating zircon to produce an excellent refractory glaze-resistant batt wash for kiln shelves.

Over time, batt wash sinters and sticks to the shelf - especially at high temperature - but it can remain powdery, so care must be taken not to allow it to fall onto pots to be glazed. For this reason it should only be used on the top surface of the shelf and not on props or the kiln itself.  An application of batt wash will last for many firings. When it becomes contaminated with glaze it can be scraped off and replaced.

FOR BEST RESULTS:  

• Mix the wash with water to the consistency of milk
• Place kiln shelf on flat, stable surface
• Apply the mixture evenly to the top surface of the kiln shelf using a paint roller or large decorators brush. 
• Once the surface is covered, repeat application at 90 degrees to the original roller/brush strokes until a satisfactory layer has been achieved.  
• Firing to stoneware will fix the batt wash to the kiln shelf
• Chisel glaze drips off before reapplying wash. ALWAYS wear eye protection whilst doing this and beware of shards of glaze which can be extremely sharp!

Tip: Add more water than usual then flocculate with saturated Epsom salt solution (magnesium sulphate) to improve brushability.
