Preheating...the cure for 'Culls'...
I've used the hot plate for some time now and it makes a difference...but...when I made this simple little enclosure, 'garage' it really made a difference.
I can measure the heat level at a glance with this cheap oven thermometer. Before, I used the hand held electronic version of Harbor Freights thermometer...it would measure differently at every point I pointed it at, frustrating and which measurement do I believe?
Now with this simple rig when the thermometer reads 350-400*F. my mould is ready to go on first pour most of the time.
This isn't my idea, someone posted about these tin cans some time ago...it just took me a while to actually try it...glad I did.
