I like to work on individual Kaiser Lee Board kiln shelves to set up my work. <\/p>\n

Do I have to use kiln wash on your Kaiser Lee Board?<\/span><\/h2>\n
<\/div>\n
If you want to kiln wash Kaiser Lee Board kiln shelf, use either Boron Nitride or Primo Primer. But we do not recommend kiln washing for reasons explained below.<\/div>\n
<\/div>\n
In Germany I learned to use only kiln wash in its dry stage rather than mixed with water  – just powder it onto the shelf and add more as needed. You have to be careful when placing your glass on it so that you don’t get any on top of the glass, but other than that it works fine.<\/div>\n
<\/div>\n
<\/div>\n
<\/div>\n

Can I use no release at all?<\/span><\/h3>\n
<\/div>\n
Yes you can, glass does not really stick to Kaiser Lee Board. It will pick up some of the particles and will be rough on the back – which could be good in the case of wall mountings like tiles or back splashes. Opalescent colors are more aggressive than transparent colors or clear. Clear luminescent glass works well with just kiln wash powder.<\/div>\n
<\/div>\n
Iridescent or dichroic glass does not stick to the board either if you are using the coated sides toward the board.<\/div>\n
<\/div>\n
\n

Will the glass ever stick to Kaiser Lee Board?<\/span><\/h3>\n<\/div>\n
<\/div>\n
The only time I have glass picking up a junk of fiber is when I melt glass to its liquid stage for raking. I’m using a different kiln and a designated Kaiser Lee Board for this process.<\/div>\n
<\/div>\n
Another issue could be, if you treated  the shelf with regular wet kiln wash (other than Primo Primer)). This type of kiln wash is known to stick to the glass sometimes and than it will rip fibers from the shelf. So please never treat your kiln shelf with regular kiln wash.<\/div>\n

\n

Should you use shelf paper?<\/span><\/h3>\n<\/div>\n
<\/div>\n
I use shelf paper if I want a smooth backing or if I do “construction” art work with many pieces, which I glue to the paper with Fuse It Tack Film.<\/div>\n
<\/div>\n
<\/div>\n
\n

Do you have any tips on care and maintenance?<\/span><\/h3>\n<\/div>\n
<\/div>\n
Kaiser Lee Board is easy to carve so be careful when you place something onto your Kaiser Lee Board kiln shelf so you won’t scratch it. I<\/div>\n
<\/div>\n
Minor scratches are easy  to smooth  a knife sharpening or soft sanding block. Use only very little pressure and go over it lightly and evenly. Once you feel like your shelf is not good enough any more, turn it over and use the other side. And later on you can always make a mold from it. I have used my kiln shelves for over 12 years nearly every day.<\/div>\n

With this step down method you can full fuse and slump a 2″ deep bowl in one firing with the firing schedule below. [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”3.24″][et_pb_column type=”4_4″ _builder_version=”3.24″][et_pb_text _builder_version=”3.24″]<\/p>\n

<\/div>\n
\n

Can you give me some type of idea or typical fusing schedule?<\/span><\/h3>\n<\/div>\n
 <\/div>\n
Here are 2 fusing schedules that are typical when using Kaiser Lee Board as your choice of kiln shelf and mold.<\/p>\n

 <\/p>\n<\/div>\n

\n

 Full Fuse and Slump Schedule<\/strong><\/h4>\n

<\/strong><\/p>\n

<\/strong><\/p>\n<\/div>\n

    \n
  • \n

    Ramp up 600\u00b0F (315\u00b0 C)<\/em> per hour to 1000\u00b0F  (537\u00b0 C) <\/em>and hold for 10 minutes<\/span><\/span><\/h4>\n<\/li>\n
  • \n

    Ramp up as fast as possible (full = the setting after 0) to 1420\u00b0 F <\/span><\/span>(480\u00b0 C) hold for 10 to 20 minutes or desired result is achieved. <\/span><\/h4>\n<\/li>\n
  • \n

    Ramp down full to 900\u00b0F (480\u00b0 C) and hold for 1 hr<\/span><\/span><\/h4>\n<\/li>\n
  • \n

    Ramp down 100\u00b0 F <\/span><\/span>(37\u00b0 C) <\/span><\/span>per hour to 700\u00b0F <\/span><\/span>(370\u00b0 C) <\/span><\/span>hold 1 min.<\/span><\/span><\/h4>\n<\/li>\n
  • \n

    Let cool to room temperature.<\/span><\/span><\/h4>\n

    <\/span><\/p>\n

    If a piece is already fused and has to be re-fired again I slow the process down by changing the ramp up from 600\u00b0F to 300\u00b0F  (315\u00b0C to 150\u00b0C)   <\/i>per hour.<\/strong><\/span><\/h4>\n<\/li>\n<\/ul>\n
    All you need to adjust now is the target temperature for slumping and draping.<\/div>\n
