QWORK Durable Porcelain Crucible with Lid, 300ml Capacity, for School, Laboratory, 4 Pack

Look very similar to the ones I’ve bought many years ago or used in high school decades ago. The only thing is to put them under stress and heat them up. I hope they can stand my Terrell Bunsen burner.

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.

Great crucibles, good price, come wrapped in bubble wrap inside a cardboard box. Unfortunately this is still not good enough to prevent breakage - the crucibles need to be paper-wrapped individually or at least sandwiched with paper to save them in transit, yet this hasn't been done.

Able to stand all the heat I throw at itWork as described

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.

Not very happy at the moment I opened my package just to reveal that two items are broken. Very disappointed

No dislike, liked that I was able to use it right when I got it..

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
