I was mostly joking, I'm not sure if it is possible for there to be any kind of off-gassing or leaching of chromium from synthetic rubies.
Chromium is a dangerous heavy metal and some forms of it are extremely toxic. It is mentioned in the Erin brockovich movie which is based on a true story about how PG&e polluted a towns water with chromium and a whole ton of people got sick.
Aluminum is not good for you either, but it is not a toxic heavy metal.
Aluminum is a highly reactive metal. The bonds between it and the oxygen in Sapphire are very strong. That is why it has such high chemical resistance.
Did you know that sodium is a highly reactive metal that explodes when you add it water? It is rare to find it in the elemental metallic state, it is most often found attached to chlorine a highly-corrosive oxidizing gas that would melt your lungs if you were to breathe it straight. Sodium chloride is known as table salt.
You seem to be very concerned with the chromium impurity atoms in ruby, why does all the aluminum present in both sapphire and ruby not give you pause?
Isn't possible that some people have more sensitive palates than you do? Perhaps they are tasting something that you don't.
There's much more to dicuss in your post, but I have to get back to work. Pretty much agree with everything
@JCat has said.
I'm a great cook and I feel that I have a sensitive palate. Like I've said I have tasted bad taste from both quartz and titanium when I use temperatures that were not optimal. I have also tasted bad taste from quartz and titanium rigs that were dirty.
I am not having any bad taste from the liger air, it seems to be self cleaning and I feel that I had the temperature pretty well dialed in.
From what I can tell they are three main factors that have been at play when people have reported poor taste. These factors apply all materials and are more a product of design than material.
* Older versions of a liger can become dirty overtime and that can cause a bad taste
* Temperature and coil issues possibly related to a bad Ah update
* Overloading the physical and thermal capacity of the liger air with .5 gram or larger dabs might lead to splatter and spill over issues.
I could see how if you're putting half gram or more dabs in there then you would need a higher temperature or you would benefit from a larger rig with a total higher thermal Mass. It has nothing to do with the titanium and everything to do with the thermodynamics and shape of the dish.
Personally I don't see the need of going over 0.1 gram per dab. I mean are you 0.5 people actually inhaling all that in one hit? If not then why don't you do multiple regular sized dabs? The liger air works best when used as a personal thin film distillation device. You want to use just enough dab to completely coat the inside with a thin layer of material. The thinner the film the easier and more cleanly it will be vaporized. The ideal amount for the liger air is somewhere around 0.1-0.02 g. This will get you the cleanest and best tasting hits. The use of the electronic nail allows you to take one rip after another with just a quick swab in between.
