How to Make Fused Glass Jewelry in a Microwave


If you are not quite ready to make the big purchase of a full-size kiln, Jen-Ken Kilns has developed a smaller kiln, designed to be used in your microwave oven. It can reach up to 1,650 degrees F and can fuse most items in under 10 minutes. Microwave kilns are affordable and a great choice for those operating their own home-based jewelry business.

Beginner fusing kits come with everything you need to get started. Some even include a starter project. This is a more affordable way to begin fusing glass. To buy these items individually would substantially increase your initial cost.

Things You'll Need

  • Microwave kiln
  • Glass cutter
  • Dichroic bits and pieces
  • Millefiori glass
  • Confetti glass
  • Fusing glass
  • Kiln paper
  • Hot mitts
  • Glass adhesive
  • Cut your glass pieces ideal to the size needed for your project.

  • Cut your kiln paper and put on the kiln base.

  • Layer your glass on the kiln base in the design for your project.

  • Cover with kiln lid and place inside the microwave.

  • Heat on high for two minutes. Adjust accordingly depending on wattage of your microwave.

  • Using hot mitts, check progress of your glass. Continue to heat in increments of 30 seconds until fusing is complete.

  • Take the kiln out of microwave and allow to cool for 45 minutes keeping the lid on.

  • Attach jewelry findings appropriate for your project using a glass adhesive and allow to dry.

Tips & Warnings

  • Microwaves and kilns fire at varying patterns and intensity. Keep notes to use for later projects.
  • Low-watt microwaves, fewer than 1000 watts, may require an initial firing time of up to four minutes instead of two minutes.
  • Recommended fusing times: 1,200 watt microwave--Two minutes; 1,100 watt microwave--two minutes and 30 seconds; 800 watt microwave--four minutes.
  • Removing glass from kiln before it is completely cooled may crack your glass.
