Hi all.
I have a pre cast oven.
I have finally got my temperature up to full temperature after around 13 progressively hotter curing days. 4 Cracks have appeared. I know that they aren't desirable and am gutted that I have them this early. I'm not sure if it is my fault or if they were just inevitable either way doesn't matter now.
What I would like to know is are they anything to worry about?
Is there anything I should do to stop them getting worse?
They shrink down to hair lines when cooling.
Mano Thanks

I've not any experience with cast material, but MUCH with clays, both alone and with adjuncts like cone 6. Cracks are usually a thermo cycling issue and rather benign. Consider taking a measure on them and monitor. if they grow in length, chances are they'll also deepen (at some point). Should that happen sink a paperclip and get a depth. Lastly, do you know the cast material? Good to find out. Best of luck!
