I don't know if I'm gonna help you any, but here goes... I bought a small digital scale at Wal Mart. When I weigh my wax, or FO for that matter, I can set the pot or measuring cup on the scale empty, and it registers as zero. It has a little button that you push to set it to zero. I also use wooden spoons and a little butter knife to scrape excess wax off the spoon. If you have a presto and don't want to scratch it up, use the wooden spoons. I normally (and I don't know if it's totally wrong, but it's worked for me) stir the color/FO into the presto, then using the spout, drain it into the pour pot then pour. I use paper towels to wipe up the inside of the presto. Anyway, that's how I do it...
