Oh yeah! We buy "kraft paper" by the roll at BORG. My casting work station is a maple top work bench. We roll the craft paper over the bench before each casting session and pull up the old immediately after each session.

No matter how careful you are, this is messy business. Imagine mixing maple syrup with thin CA:).....and that's how messy the UNCATALYSED resin is!!!

I've never had a problem with messes. I used to cast on a counter top in my shop and it still looks brand new. Maybe some are a little more excited than others while casting or maybe the coffee?

One thing about casting with cutting board molds... most people make them large (enough for 6 or 7 blanks) but, the the bad thing is, in my case anyway, is I don't need 6 or 7 pens of the same color. If you plan to sell, then that would be beneficial.

The transluscent colors can be combined with the mica's to obtain an opaque blank or use it to your advantage to create a unique blank. You will more than likely be painting the blanks and/or tubes anyway.

The most important thing is... DO NOT cast inside the house and where you do cast, have PLENTY of ventilation!! A quality mask is a good idea as well. The odor isn't just to upset your wife... it is VERY toxic!! Read the MSDS on it and understand the risks and warnings or your casting career may come to a halt, suddenly. These are chemicals...not brownies. Be safe and enjoy casting.

That point is not lost on me. Thank you!

It may well be that I have to wait a few more weeks until it's a little warmer. It was 7 degrees this morning! I think it stays even colder in my little shop. Had hoped I could do the casting in my basement shop but that may not work after all.
I need to dig out my old pressure tank that I used with my HVLP unit. If nothing else it might be a way to seal the fumes in while the casting sets up ????

A HF ultrasonic cleaner with heat makes bubble free casting much easier.

Recycle code 5 plastic cups work great as mixing cups ($2 for 64 cups- family dollar and dollar general stores). Coded 1 & 6 make a big mess. Sour cream and cottage cheese containers and all rubbermaid products work well. The small sour cream cups make great bottle stopper and shaving brush molds as do empty pill bottles.

DO NOT follow U.S. composite 's recommendation of 10 drops of catalyst per ounce. 5 drops is PLENTY! 4 drops is better, here. Some in your climate conditions perfer 3 drops per ounce.

If you have questions pm me or call, I think you have my toll free number.
This is good to know. I was reading the catalyst amounts I downloaded from U.S. Comp, so thanks for the. Heads up. Just got my Resin Savers and ordered my Silmar41 today. Picked up an ultrasonic at HF on sale and will be hunting cups at the dollar store next. I'm starting with clear pours for some stamp blanks and might venture into color mixes when I can wrap my head around some of this info.

I can see that I'm going to be hooked!

Don't cast in your basement! DAMHIKT
haha dad almost banned me from casting on that one, now I cast in my unheated sunroom with ALL the windows open, and I dont open the door 2 the house for 24 hrs,((or 6-8 if its above 65 degrees)) I actually go out the back sunroom door and around the house into my front door to avoid exposing my family to the fumes
