AI Thread Summary
The discussion centers around identifying substances that can burn at mild temperatures (4 to 40°C) in the presence of oxygen and fire, producing colorful flames. Participants clarify that while many combustible materials can ignite at these temperatures, achieving vibrant flames is more complex. Boranes are mentioned as a substance that burns with a green flame when released into the atmosphere. The conversation also highlights that creating colorful smoke is challenging under typical conditions. Overall, the focus is on the specific properties of materials that produce distinctive flame colors when ignited.

Sorry guys I am not an expert, but I wondered for my general use

What substances do you know will burn in mild tempratures (4 to 40 C, let's say) simply in the presence of oxygen and fire (spark or surrounding fire) creating prominent colorful fire - hence different from white, gray or black. I heard copper has this feature, but I am not positive about that. Can anyone please help?

Sorry for bad english...
 
Chemistry news on Phys.org
There are no substances I am aware of that will burn in these temperatures.
 
when the surrounding environment (air) is at these tempratures?
 
I am not sure what you are asking about. Most combustible things will burn when surrounded by the air at 0-40 deg C.

Do you want it just to burn in typical circumstances? Like a match, or a torch, or a campfire?
 
He is asking about pyrophoric materials. Boranes burn with a green flame. All you have to do is to release it into the atmosphere. If you want smoke instead of colored flames that is a different thing altogether.
 
Thank you guys for replying! now I know colorful smoke is hard to achieve in normal circumstances... and Chemistree got me all right
 
Thread 'How to make Sodium Chlorate by Electrolysis of salt water?'
I have a power supply for electrolysis of salt water brine, variable 3v to 6v up to 30 amps. Cathode is stainless steel, anode is carbon rods. Carbon rod surface area 42" sq. the Stainless steel cathode should be 21" sq. Salt is pure 100% salt dissolved into distilled water. I have been making saturated salt wrong. Today I learn saturated salt is, dissolve pure salt into 150°f water cool to 100°f pour into the 2 gallon brine tank. I find conflicting information about brine tank...

I tracks prices of Pt, Pd, Ru, Ir and Ru. Of the 5 metals, rhodium (Rh) is the most expensive. A year ago, Rh and Ir...
