craftgrrl | silkscreening question

Hello all,

I've googled this and the only links I actually got were from this community so I figured I'd ask here. (hehe i know this is craftgrrl so hopefully none of you will be offended that boy is posting ;) )

My bandmates and I recently invested in a 1 color silkscreen press..

I bought a kit at micheals that included the screen and everything...

so my fist attempt really didn't work out at all.

The emulsion didn't wash off completely.. I wasn't using a strong enough light.. so I left it for longer then suggested..

This time i'm going to try using 2 transparencies and I'm buying a proper photo flood blub (or at least a 150w light) and leave it for the said amount of time (i think it's 45 mins)

okay here's where i'm getting confused..

I bought some more photo emulsion from a local art store (she had to order it in)

it's a 26 oz diazo photo emulsion.. how much sensitizer should I use with it?

the lady at the art store wasn't 100% sure.. she had the kit and it has a 1oz bottle for a 4oz emulsion bottle...

she sold me two 2oz bottles of sensitizer.. does that sound about right? part of me is thinking if they only make the 2 sizes of emultion you'd think one bigger sensitizer would be enough... but math tells me otherwise.. anyone have any idea?

any help is much appriciated
