Create your own glass in the kiln using the new High Grade Stainless Steel Diamond Flow Grid. Elevate the Diamond Flow Grid above your shelf in the kiln and stack your favorite colors of fusible glass on top. After the glass becomes molten, it will flow through the Grid and cause quite a stir in the glass! You will be amazed at the unique pattern that the glass has become on your kiln shelf, begging to be your next work of art!

    I tried out the diamond flow grid, but was very disappointed in the results. I put on scraps from a piece that was broken. I covered most of the grid. It was a mess. The information that came with the grid didn’t tell you anything except to go to 1500 degrees. It didn’t give a schedule or tell you how to set up the glass prior to firing. Very poor instructions. Also the grid is no longer nice and flat which surprised me since the glass was spread out over the entire area of the grid.

      Hi Kerry,

      I am sorry to hear that you had less that great results. In order to help you, I need some more info. Did you happen to take any photos of before and after? I would like to see how much glass you had and how you had it set up.

      I tried to keep the instructions clear and simple to avoid confusion. Since it is not really a specific project firing, a one six fits all schedule did not seem appropriate. Since a person is generally putting scraps and small pieces on the grid, the actual values of the ramp up aren’t really important, in other words, get the glass hot. The process temperature of around 1500 degrees is an approximate value too. In other words, some glasses and situations, depending on volume, color, COE, etc. flow at lower/higher temps. Therefore, both the temp and time held there are subject to the operator firing the kiln. In the instructions it is stated, “until the desired effect is achieved.” The cooling / annealing curve would depend on the usual thickness cross-section guidelines. One could refer to the glass manufacturer for those values.

      Because of the many different effects that can come out of the firing of glass in a flow setup, describing the actual setting up of the glass could be as simple as putting the glass on top of the grid or as involved as trying to plan exactly how the glass will flow and mix. Much like other “flow’ firings such as “pot melt” & “flow bars”, we are somewhat the mercy of the “Glass gods.”

      Having said that, one tip could be that in order to have glass flowing through the grid, there must be sufficient mass to overcome the surface tension of the bridge between the grid lines to actually have the glass to flow downward. Too little mass and the glass will sit on top of the grid. This could be overcome with more temperature, but the grid will get softer and deform more.

      It is not unusual for the grid to slightly deform during firing depending how much mass is added. It is important to support it on all four sides as stated in the instruction sheet as well as the illustration. Failure to do this will allow it to droop excessively. It can be straightened after cooling by applying a properly protected foot (no flip flops) on a flat surface.

      I hope this sheds some light on your situation. Again, send me a photo if available, and thanks for the input, I am always trying to improve.
