New crucible design is fabulous! Charcoal basket and ash pan lift out! Game changers!
It cook great
Great
Great improvement
Update 7/8/2025: I used the grill during the 4th of July Holiday and with the new Crucible, the grilling experience was outstanding. The New Crucible was a game changer in the grill process. It allowed me to start the grill in minutes and was ready to grill within 15 minutes. The Crucible allows for more dynamic air flow in the fire box area which also allows the grill to get the hottest it has ever been. I also noticed the lump coal burned full to all ash without leaving any unburned coal in the Crucible hopper. This is one of the best investments in my grill and now that it is much easier to start, I plan on making the Saffire grill my main go to grill. I believe your organization can do some customer notification on this upgrade which will change their landscape on grilling.
seems durable. easy to clean out… fire takes longer to start and temp is very difficult to regulate for long cooks compared to original
Hi Steve! Thanks for your review.
For faster starting, generally:
– Shake the charcoal basket before each cook to knock the ash down into the ash pan.
– Dump out the ash pan when the ash has built up enough to get in the way of the air flow that should be coming in through the bottom of your grill. (Never let the ash reach the bottom of the charcoal basket!)
– Make sure to use enough charcoal, just like you always have. But, try not to cover the handles, as that much charcoal could restrict air-flow.
For temperature regulation, remember that with more air-flow under the charcoal bed, you get a stronger and more resilient burn. Control the air-flow to keep that burn under control!
– Make sure your gasket is sealing correctly. If not, replace it.
– Make sure you are using the bottom control first to control the temperature, and then only closing down the top to fine-tune the temperature.
That should help. As I mentioned in my email, we are available to help if you continue to have issues.
Super happy with the new crucible fire box. I do not use any other grilles or smokers any longer. This is the only one I use!
This is a good replacement for the old style of firebox and should last a long time.
Great upgrade to my grill
Was a perfect fit and replacement for my older ceramics
This was an upgrade for my existing Saffire grill. Its a great upgrade. It adds more space for charcoal as well as a very nice ash basket. This along with the multi-tier grater system had made my already great grill even better. It is very well built and was delivered quick. As usual purchasing from Saffire has been quick and easy.
Great upgrade to the old style. Excellent quality
Love this new firebox. Great Upgrade!
Although I have enjoyed my Sapphire Grill for almost a decade ,the new Crucible firebox takes the experience to another level. The Crucible comes to temperature rapidly, and provides the ability to hold temperatures more accurately. It is efficient with regard to charcoal usage. It uses far less than my previous fire box. I think it has been thoughtfully designed. Seems they have another good addition to an already strong lineup.
I loved my Saffire grill before the new crucible, but my only complaint was airflow and taking too long to get up to temperature. With the new crucible in, it raises the temperature faster and will get hotter with less charcoal than it did before. A worth-while upgrade for sure!!
