I think they are really cool, especially the last one. Which Pyro recipe are you using? There are a lot of different ones out there. I like 510 Pyro, it's really easy to make and quite concentrated. I'll have to find the recipe or you can google for it.

Mark: here is the recipe for 510 Pyro.

510-PYRO
TEA (Triethanolamine) 75 ml
Ascorbic acid 5 g
Pyrogallol 10 g
Phenidone 0.25 g
TEA to make 100 ml

Mixing instructions:
You need to heat the TEA to about 150°F to dissolve this stuff. Be sure to wear a breathing mask and gloves. the pyrogallol is toxic. :eek:

Add chemicals in specified sequence.
Dilution: 1+100
Starting point development time: 5-7 mins.
Notes: Can also be diluted up to 1:500 for EDRA (extended development/reduced agitation) techniques, with one minute initial agitation, followed by one inversion every 10-15 minutes for one hour, or so.

You can find development times in the Massive Development Chart I have been diluting it 1:100, works well.
