Simple operation and high quality make the School Master series a must for the K-12 community.  Proprietary One-Touch Intuitive Kiln Control is designed for busy school teachers - One touch and you are ready to fire the bisque and glaze programs typically used in schools (also easy to adjust simple parameters like cone, delay, hold, heat-up and cool-down rates). You can even create four custom ramp/hold programs.

L&L Ceramic Element Holders 4 Key Control Kiln Brick Reflective Coating
L&L Ceramic Element Holders
L&L Kiln's patented hard ceramic element holders protect your kiln. The ceramic element holder protects the soft fragile firebrick. Replacing elements repeatedly does not damage the brick. Elements don't sag or fall out of broken grooves. You do not need metal pins to hold elements into broken grooves. Customers often say their L&L kilns look new after 30 years of hard use!
Standard 4 Key Digital
 The new One-Touch Intuitive Kiln Control was designed for busy school teachers, contemporary studios, and hobbyists. One touch and you are ready to fire the bisque and glaze programs. No programming is necessary, simple adjustments are easy, yet sophisticated programming is possible.
Proprietary Reflective Ceramic Coating
L&L coats the firebrick with a proprietary reflective ceramic coating which penetrates, binds and hardens the surface of the entire interior of the kiln. This will reduce brick dusting, makes the kiln interior more durable and helps improve energy efficiency.
