    Hi, I mostly use float glass for fusing as I can hardly get any specialty glass where I live (Cyprus.)  Could you please advise on firing schedules for  fusing and slumping float glass?

    Many thanks,

    Kazelis.

    You can use the schedules on this site (https://fusedglass.org/tools/firing_schedules) with the following changes:

    • Increase the top temperature by 100° F (55° C) . For example, the schedules on this site recommend full fusing most projects at 1475°  F (800°  C).  For float, you will get simillar results at 1575° F (857° C). For slumping you may not need the full 100° F.
    • Begin your anneal at 1030° F (554° C) – instead of the 960° F in the schedules.
    • Change the mid annealing point (where the rate changes) from 800° F to 900° F (482° C).
    • Finish annealing at 800° F (427° C) instead of the 725° in the schedules.

    That should work for most window and bottle glass.

    Many thanks for your advice.  Fusing schedule very similar to the one I use (My top temp. for 2layers of 3mm glass is 827 degrees, but annealing is the same) I was wondering about the slumping schedule.  Will try it out and let you know.
