    Hi,

    I made a serving dish with a transparent cobalt blue base. On the design layer, I used several colors of of transparent and opaque glass and added some details with Glassline paint. I took it to a full fuse, but was disappointed when the glassline paint nearly disappeared after firing. What I’m hoping to do is to add stronger details in gold metallic Glassline to the fused dish and then go ahead and slump it to processing temp. – 1250 degrees F with a 20 min. hold.  Does anyone know if Glassline paint will fuse at slumping temperatures? I’m trying to avoid having to take the piece to a full fuse again. I’d appreciate any thoughts or advise anyone might have on this. I used System 96 glass. Thank you~ Carrie

    In general it is best to do one thing at a time when kiln forming.  In this case you will not need to take the glassline to full fuse temp, but to a tack fuse.  I would do this first and then slump later.  The saying is that speed kils.  Certainly impatience to get to the finished result often results in breaks or cracks in kiln forming.

    Thank you for your suggestion, Stephen. I thought this might be the case, and it’s very good to know I will only need to take it to a tack fuse for the second firing. I’ll slow the firing down as this piece is now 1/4″ thick. I’m usually quite patient, but the poor Glassline paint results had me a bit frustrated. Thanks for getting me back on track!

    They may be a little dull at tack fuse temps. They do best at full fuse.

    Thank you for the information, Dana.  Shiney glass details are what I’m looking for, so I’ll take it to a full fuse.
