Testing Process

Testing glazes is a challenging yet rewarding process. Because I make my glazes using raw materials, I am consistent and exact with measurements, how I sieve, application, and the temperature I fire at.

I also test often, casting a wide net of color and surface combinations, layering glazes with underglazes, slips, and engobes.

Tools

1. Triple Beam Scale
   OHAUS 720-S0 TRIPLE BEAM 700 SERIES MECHANICAL CLASSROOM BALANCE, 610 G X .1 G
   I use a triple beam because I like to work in small batches, each glaze unique to the piece that I’ve sculpted.

2. Sieves
   I use 80, 100, and 120 mesh sieves. This ensures consistent application when I spray them on using a drop gravity spray gun.

3. Spray Gun
   HVLP and Standard Gravity Feed Spray Gun Kit

4. Air Compressor
   DEWALT Pancake Air Compressor, 6 Gallon, 165 PSI

5. Respirator
   3M Grey Reusable P100 All-purpose Safety Mask
