    Any suggestions on firing schedule to flatten Red Stripe beer bottles?  Tried different top temps but label (enamel) keeps buring off.  For every 4 that I do, 1 is fine and the other 3 burn off?

    Thanks in advance,

    John

    You have identified exactly the variable that will determine whether the enamel burns off or not.  You need to keep records of which temperature and soak burned the enamels off and which did not.  You of course are subject to the whims of the manufacturer, because they don’t have any interest in whether the enamel is of exactly the same composistion each time.

    Stephen,

    Thanks for the reply.  Just fired 5 Red Stripe bottles @ 1350 …. 4 “labels” burned off, 1 was fine.  I watched thru peep hole and it appeared that enamel started to burn off @ 1100.  I agree with your comment about composistion of enamel.  Do you think putting a coat of clear paint medium over the “label” would prevent burn off?  I tried clear coat overglaze and this did not seem to help at all.

    Thanks,

    John

    I think unfortunately that it will not help.  The enamels have their cureing temperature and that is pretty much it.

    This would be time consuming but could this person make frit out of one of the beer bottles and put on top of the enamel?   Could that possibly stop the enamel from burning off?

    Thanks,
