QWORK Porcelain Crucible with Lid, 50ml Capacity, 2 Pack, for School, Laboratory

Buen producto, útil para el laboratorio.

Preheat is extremely important for the ceramic cups… You can only get a couple of uses out of each one you’ll be blessed if you do… Lolso keep them hot while you can while they last in one pour, meaning do many pours of the one thing you’re working on… Second use usually cracks.🤷 excellent lifecycle if you ask me👍 product is excellent. Packaging is extremely well done as well. I’ve ordered many times from the seller.👌

After a break from buying QWORK stuff, I decided to give them another shot. I figured it isn't glass maybe it will be ok. I was wrong, one of the crucible lids was broken and one of the crucibles was broken. Decided to get the replacement sent, but wont be surprised if it is broken too.

I used it in a propane furnace and even though I warm it up it didn't withstand Hi heat I'll have to try it in a electric furnace overall it's convenient for the price so I might reorder another set if I do ip update and repost a new review

Small crucible with a map gas melt lead weight for a pinewood derby car. It worked perfectly don't forget to add a little bit of flux and voila it's done.
