Do you need to seal and protect these boards to protect them from splitting or warping?

I think, yes. Both handles are now split ('now' is 3.5 years after I purchased the set). I always did cleaning them by hand only but I didn't follow any instructions other than those I already knew

The instructions told us to so we did as instructed. If you did not receive those instructions with the product, I would send it back for an exchange.

The ones I got were sealed. I do not believe you can take them apart without breaking them.

Yes, they are, and they don't need protection between them--BUT the plates do. If you don't put a paper plate or paper towel or something between the RR plates they will get scratched and damaged.

Yes. I wash mine in the dishwasher all the time and have never had a problem with warping or mis-shapen seals. I usually wash the lid on the top rack and the container on the bottom.

No warping. But I wash and dry immediately. Holds up to my Cutco knives. I do oil once a week.I use oil made for boards specifically. Other oils smell rancid. ENJOY. HOLIDAYS ARE HERE......

they withstand heat pretty well, but not super hot. They can warp if you get them too hot.

So far (a few years now) I have not had any issues with these warping and I use them often on my flat, ceramic top stove. I have had others that did (coated inside so they don't stick).

No extra piece/layer on bottom. I've owned mine for 6 months with no warping at all.

Not unless you remove the protective coating from them. I believe there is a clear lacquer on them as a preventative.

I have two of the smaller boards that I have had for a out 12+ yrs. they go in the dishwasher daily without problem. I am purchasing the 15x21 because I like the smaller ones a lot. They will stain but occasional bleaching makes them white again. Will definitely report any problems with warping.

I haven't seen then warp but I don't use them very often and at average baking temps. They aren't very heavy.

I know they caution against high temps but nothing on low temps causing warping. The best way to know would be to contact the company.

Yes, I've used these pans under a broiler on high multiple times. I had no problems with warping like thin, cheaper pans. They are great, solid and thick aluminum.

No issues so far you just need to make sure you lay them very tightly/closely together so you do not get any cracks between tiles.

So far, no warping. I have had them for more than 3 months and have had them in the dishwasher several times. They are holding up great!

I have not seen any of our plates warp or any indicators of such. We have 6 of them and they get put on the bottom rack of the dishwasher. Do note though, as per the instructions, we do not put them in the microwave. I haven't seen or owned the non-divided plates, but I'd imagine they're thinner than these. These are very thick, but light, and once you hold, feel and use them the first time, you instinctively know they'll last a while through much punishment (dropping, washing, banging, etc). They're definitely worth it.

no, there is no added layers on the bottom. I have used them a lot in the last two months, so far no warping.
