Tim,(posted 9301 days ago)I've been able to purchase the chemicals required to mix PMK from a company called Vanbar. They have two outlets in Victoria and one in NSW. They have an affiliate or sub company called Photochem which will sell the chemicals you require. Their email address is Vanbar@vanbar.com.au. They have a website which is www.vanbar.com.au.
They will ship chemicals interstate and overseas.
You should know however, that Pyrogallol is expensive, about $90-100aud for 100gms which makes PMK an expensive developer. I haven't actually used it yet as I've been playing around with ABC Pyro, which Photochem sell in dry kit form of varying sizes.
Anyway, hope this helps and good luck.
