reminder: sapphire dabs rock
The quality seemed on par with my Dnail sic halos. Smooth and clean!
Appears to be the same as these https://www.dhgate.com/product/100-...ement/449342844.html#s1-18-1;searl|0765151218
You could save yourself a bit by going china direct.
I ordered a ruby insert from this vendor like a month ago and it has been great.
Are these for 25mm or 30mm buckets?
And are they legit?
25mm and ya they seem to be. It changes colour when heated, going from crystal clear ruby when cold to more of a crimson when up to temp on e-nail.
If your IR thermometer allows for thermal emmisivity adjustment (not all do) you would change the setting based on the emissivity of the material. Here's a table of coefficients for a bunch of materials (ruby would be the same as sapphire).Does anyone know how to set up an IR thermometer/ temp gun to properly read ruby and quartz surface temp?

Good info. I can't vouch for that table I referenced, I just found it in a quick google search and linked it in an attempt to be helpful. My faith in the internet is diminished with each passing day it seems.Interesting, I don't think I've seen that table, or a listing specifically for "sapphire" before. The coefficient they list is 0.48, which is wildly different than what I had been using.
The closest I could find was "Emory Corundum" on this table. Scroll down to the 2nd table, the one for non-metals, and it lists a value of 0.86.
@Stu I just changed my IR gun to 0.48 to test out my ruby insert, and can definitely say that's not the right value for it.
I have my controller set to 500 degrees F. With a emissivity of 0.86, I typically had a temp reading of the insert floor around 430, give or take depending on environmental changes. I usually have a fan going on high, so I likely have a higher delta from controller to floor temp than most.
When I changed to 0.48, I was getting readings of around 610, far above what my controller is set to.
So not saying 0.86 is the right setting, but it's definitely more realistic than 0.48.
Does anyone with a ruby insert, an accurate probe thermometer, and an adjustable IR gun want to do a service to the community? Would be awesome to do some tests and find the correct emissivity value for our inserts.

Is there any difference in ruby vs sapphire flavor / performance ?
If we are talking equal size and carat weight, none whatsoever other then ruby changes color when hot.
They are the exact same thing save for the slight chromium.
thanks so much!@Zander - A banger is made from quartz and is used to vaporize concentrates. Fitted to a water pipe via standard gong joint, the bucket is heated with either a torch or enail coil and concentrate is placed on the hot surface. A carb cap is added to the top of the bucket while the user inhales the resulting vapor. There's a myriad of options available in shapes sizes and price ranges and (the topic of this thread) gemstones - you might find this thread informative - or google 'quartz banger'.
Does the ruby change color at a good temperature for dabbing? (So I wouldnt have to use an IR gun)

I still wish I knew the correct value!
