PMC or Art Clay Silver (Fine Silver Clays)

Any one of the fine silver clays mentioned above can be fire successfully in the MicroKiln.  Firings have been conducted with and without stones and glass.  If you are using glass in your fine silver clay design you must pre-fire the glass to the desired shaped before setting it into the clay.  I realize this sounds like a common sense thing to do, but you would be surprised at the number of people who ask me about firing glass cabs and beads with fine silver clay.

Below are simple designs using PMC and Art Clay Silver (not mixed together) with and without a glass cab.  Both were fired in the MicroKiln; however, ones without glass were fired at a different time using an entirely different firing schedule.

The key to having a successful fine silver clay firing is the sintering.  Anyone can fire fine silver clay, but if it is not sintered it is not considered a successful firing and thus break due to its weakness.  Sintering to me is the process of fusing (melting) silver particles together to form a solid mass that is very strong yet can be bent without breaking.  Yes, a sintered piece can be broken but that would be considered a deliberate break.  Any object that can flex with enough bending will eventually break.

Welcome New & Existing Users of the Microwave Kiln

My name is Sylvanye "Sam" Roh, a full-time warmglass artist and instructor.  I have been testing and working with this revolutionary product since June '07 and started teaching the effectiveness of its use in the design and creation of jewelry in November '08.  I travel throughout the United States instructing students on its use and teaching students abroad using video conferencing tools.  The product used in my "Microwave Kiln Jewelry" workshops is known as the "MicroKiln" and my company, Designs by Sylvanye Glass Studio is one of its United States distributors.

I have discovered that hands-on training (workshops, video conferencing, etc.) written detail instructions (step-by-step with pictures, graphics, and text) and an opportunity to ask questions (How?  Why?) related to their design outcome ensures that they will create better designs, because they have gained an understanding as to what it takes to create a successful design or to correct the one they’ve created. You know the old saying, “You don’t know what you don’t know”.  Well, its true…………..

Have you ever tried to fire a design in your microwave kiln only to have?

·      Glass melt into a blob.
·       Top sheet of glass slide off as it fuses to the base.
·       Fine silver clay shrink up into a ball.
·       Ceramic jewelry bisque melts and shrinks.
·       Enameled copper jewelry curl up onto itself,
·       Glass stick to the base or side causing the kiln material to pull away.
·       Taking longer to fire designs.
·       And many, many more ……………….

If any of these have ever happened to you, do not throw away your microwave kiln.  I can help you resolve or at least understand the problem(s) and hopefully correct it the next time you use your kiln.

Now let us discuss what this BLOG IS what and IS NOT.....................

What this Blog IS & IS NOT

 What this Blog IS
This blog has been created for those individuals experiencing problems using their microwave kiln to create jewelry designs.  Solutions will be provided to you in the form of text, graphics, and or pictures. The solutions provided will come from a variety of sources but primarily from users like myself who have experienced these problem first-hand and have either solved them or found a work-around.

What this Blog Is Not
This blog is not an instructional "how to create a design” but rather one that will help you improve or correct your existing or potential design.  This blog will also assist you in learning about your microwave oven as well as your microwave kiln since there are so many on the market today.


Let me start by showing you examples of the good, the bad and the ugly to see if you recognize any of these.  In the meantime, I welcome your questions, comments and suggestions as well as pictures depicting your experiences.  A picture of the problem you are experiencing helps a lot in determining a workable solution.

Please be aware that all microwave kilns, microwave ovens and even fiber papers are not created equal.  In other words you might have a friend that has the same type of oven (stove) as you, you both bake the same type of cake using the same ingredients and baking pan however; yours happen to turn out better.  Something is different, what is it?

Can you tell me what the problem is and what caused it in the samples below?

PROBLEM:  Chips or cracks in graphite lining due to one or more of the following:
- Melted glass, metal clay, etc. stuck to lining and pulled loose.
- Portion of lining chipped off during packing or transporting of kiln.
RESULT:  Missing graphite lining will cause cold spots and result in glass not fusing evenly.
SOLUTION:  The MicroKiln Repair & Recharge kit will remedy this problem. 

PROBLEM:  Kiln base damaged due to one or more of the following:
- Glass or metal clay fired too hot too long.
- Firing glass or metal clay without a fiber shelf & fiber paper.

RESULT:  Glass or metal clay burns hole(s) in kiln base.

SOLUTION:  Always fire with a 1/8" fiber shelf and 1/32" fiber paper. Fuse glass and sinter metal clay at the correct temp and rate based on your microwave oven's wattage.

PROBLEM:  Metal clay design melted.

RESULT:  Metal clay design destroyed resulting from over firing (fired too hot, too long or combination of both).

SOLUTION:   Fire and sinter metal clay at the correct temp and rate based on your microwave oven's wattage.


PROBLEM:   Black based dichroic etched design displays part of clear top fused glass layer on upper left of design.

RESULT:  Glass design not attractive and will need to be cold worked and fire polished to correct.

SOLUTION: Top layer of glass needs to be properly cut and balanced over base glass otherwise the heat will cause the top layer to shift.

Below are a few pictures of designs that were successful created using the MicroKiln:


   Looking forward to hearing from you and seeing pictures of your designs.
