Hi I have another question for the casters. What brand of plastic cups do you use? I have used the red 18oz Chinet 16 oz red Dart and the red transparent Solo. I have had the bottom melt out of them. It was only waiting for 10 -15 minutes. I now double cup them but am afraid that the melted plastic will affect the PR. Im still learning on this so thats why all the questions. Thanks Rich H.

Last thing I used was a washed out used yogurt container recycled from the recycle bin. I remember seeing a post on a number you should look for on the bottom of the container. Search Glass Scratchers posts possibly.
 
a while back, there was a cookware company giving away their silicone muffin pans. all you had to pay was shipping. Get yourself one of those and you will NEVER have to buy cups again!!!


I happened to have one lying around that my mom gave me a while back. My wife tried to make muffins with it, and didnt like the way they turned out. She offered it to me to make bottle stopper blanks with, but the cups are too wide, and not really tall enough. Then i got to looking at the cups and realized that they would be PERFECT for mixing and pouring!! (and even casting pendant blanks!) My muffin pan had 6 little muffin cups (about 4 or 5 oz. each at least) I cut them all apart, and they are AWESOME! they are flexible, so you can smush the top of the cup while you pour so it comes out in a nice thin bead, or you can just pour it and it comes out in a hurry! let the thin layer of PR set up in the cup and peel it right out and start over!


In fact, i have a practically brand new box of the solo 3 Oz. paper cups that work good, but are obsolete now.
 
not to mention, there are two other advantages to the silicone muffin cups...

Less trash. Most guys use some sort of plastic disposable cup to mix. three colors per pour, three pours a week... that is 9 plastic cups a week PER homebrew station going straight into the landfill.

SAVES PR. The 1/4 Oz. of PR that most guys throw away that is stuck to the bottom and walls of the mixing cups is harvested and used as addatives in future pours. (I save my shavings for the same reason.)
 
I use glass jars from the kitchen. Some of them can be used several times before the "left over" in the bottom gets too thick and reduces the amount of polyresin that can be added. Once the polyresin hardens I break the jar and toss the resin p;ug into the trash and the broken jar into the glass recycle bin. I suppose the guys who do colored resin could use the plugs for stopper blanks with some thought beforehand abouit colors.
Do a good turn daily!

I only use plastic when I use my ultra sonic cleaner and the cups need to be in water.I use cheap 9 oz. paper cups,and they work well.Were throwing away resin coated cups so its all bad for the landfill.The only thing I can do at this time is iron out my recipes and then make larger batches at a time to cut down of waste.Good Luck,Victor
 
I use the Dixie 5oz wax coated paper cups. I will definitely look into sillycone. I hadn't thought about the mini muffin pans.
 
I've found that large plastic vitamin bottles work quite well. I just hack the top off with my band saw and I have a good sized mixing cup... and once the residual resin cures in it, it pops right out making the "cup" reusable.

Hint - smaller vitamin bottles make great bottle stopper molds.

When I did fiberglass work I was told to not use wax cups because the wax will contaminate the fiberglass and cause it to not be as strong, I use Dixie paper cups for hot liquids thy don't have a wax coating.
 
Thanks Everyone for the info. The red cups that I was using had a 6 stamped on the bottom. After mixing everything up by the time it was setting up to pour into the molds the bottoms were getting really soft. So I found some clear cups with the #5 on the bottom. Will try them out tomorrow Rich H
