I have an electric oven and two digital thermometers, one I'm going to put in a piece of acrylic and the other one I'm going to use to monitor the oven temperature itself . I'm worried that the thermometer in the acrylic won't register until it gets heated throughout, and so then the oven temp might go higher than it should. So between the two readouts I can heat it gradually up. It'll be a long
night.</div><div> </div><div>Brian<br clear="none"><br clear="none">--- hanker_20032000@yahoo.ca wrote:<br clear="none"><br clear="none">From: hank pronk <hanker_20032000@yahoo.ca><br clear="none">To: Personal Submersibles General Discussion <personal_submersibles@psubs.org><br clear="none">Subject: Re: [PSUBS-MAILIST] annealing acrylic<br clear="none">Date: Mon, 24 Mar 2014 17:22:32 -0700 (PDT)<br clear="none"><br clear="none"></div><div class="yiv4495100118yqt5755845698" id="yiv4495100118yqt75294"><div style="color: rgb(0, 0, 0); font-family: HelveticaNeue, 'Helvetica Neue', Helvetica, Arial, 'Lucida Grande', sans-serif; font-size: 12pt; background-color: rgb(255, 255, 255);"><div><span>Brian,</span></div><div><span>Are you going to anneal your windows yourself? </span></div><div><span>Hank </span></div><div style="display:block;"> <br clear="none"> <br clear="none"> <div style="font-family: HelveticaNeue, 'Helvetica
