Microwave Kiln - GLASS MOLDS
These are small molds which fit in a MEDIUM size or equivalent microwave kiln. They will not fit in a small one! A Medium microwave kiln has a FIRING CHAMBER BASE that is 4-1/2" in diameter by 1-3/4" high. Coat MOLDS AND THE BASE OF THE MICROWAVE KILN with four coats of kiln wash prior to use. Let them dry thoroughly.
The manufacturer says: "The secret with firing these in the MicroKilns is to slow down the firing and watch the progress inside the kiln. Start with 2 minutes at 20% power then go to 2 minutes at 40% and then 2 at 60% power. Slightly lift the lid while still inside the Microwave and check the progress. Then go 1 minute at 100% and check again. If not complete step up in only 30 second increments because from here on up the frit matures very rapidly. If I think it is close but needs just a little more I'll even do 15 seconds at 100% to take it up slowly towards the end. If you follow these suggestions they fire just fine." Failure to exactly follow these directions can cause damage to the mold and microwave kiln. A COPY OF THE INSTRUCTIONS WHICH YOU JUST READ ARE THE ONLY INSTRUCTIONS WHICH WILL ACCOMPANY YOUR MOLDS.
