Well to be honest in this case I just cooked some pasta and I dropped them in after and let them cook for a while. I forgot and then I turned it off and let it sit overnight before I remembered them and then in the morning I ran them under some cold water and scrub them off because one of them cracked. Then I put them in the fridge and then the first one that was cracked I opened up it split into. I scooped it out with a spoon and it came out nicely and this is the second one. Wabi sabi.
