    I am looking for some advice on hold times when slumping…  I have read some things that indicate no hold time, others that do.  What is your best advice?  Thanks.

    It depends upon the process temperature, thickness of the glass, shape of the mold, etc, etc, etc… there is no “one size fits all”. The closest I have to a OSFA schedule is ramp to 1100, hold 30, ramp to 1225 and hold 15. This works for 2-4 layer, relatively shallow slumps (bowls, sushi plates, etc). If you have a deep slump, small span, etc., you’re going to need more time and possibly more heat.

    The best thiing to do is observe the piece in the kiln.

    I agree with Dana that observation is the only way to know how long to soak

    For the most common shapes and projects, a 100F/hour climb to 1200F with no hold will give decent results.  We use this in our teaching studios across a huge variety of projects with consistent success.

    That being said, those advocating to make your decision by observing the glass are absolutely correct that that is the way you get the best results.

    Thanks for the answers and the advice.  Dana’s starting point has worked well for me so far.  I appreciate your help!
