Great video... I have three questions...

1.) When I pour the soap... if it has bubbles... do I need to get those out?

2.) If I'm making a 13 cup tallow soap... is the ratio 4 fl. oz of oil? What if it's eucalyptus sent? I've noticed that tallow lends a stronger unscented scent... and want to kind of cover that cowy smell... any ideas?

3.) Can I use the soap before 6 weeks?

Thanks. Great video.

I'd love to see more videos! Like hand soap, shampoo soap/bar, dishwasher soap, laundry soap etc :) Thanks again! - Rashel (East Texas)

4.) I used an immersion blender when cooking the soap... and today after it set... it still as bubbles in it? Is my soap ruined? Is it not good to use an immersion blender to mix your soap?

Here are answers to your questions:
1. Bubbles
It's not unusual to have some bubbles, particularly if your soap is very thin. The bubbles don't harm the soap at all -- they just affect the appearance.

If you're concerned about how the soap looks, you can use a spatula to smooth out the surface once you've poured it into the mold, and before it hardens.

2. Scenting of Tallow Soap
I'm not sure how much lye you are using with your soap recipe, but if you are using about 12 oz of lye, then 4 ounces of eucalyptus or another strong scent, such as mint or lavender, would be about right. If you were to use a lighter scent like lemon or citrus, then you'd need more of it -- about 5-6 ounces.

If you want to give your soap a certain smell or make it smell different than unscented soap, adding scents is a great way to do that. Normally, I don't find the smell of unscented beef tallow soap unpleasant at all, but you do want to take care not to let the tallow go rancid (which could definitely increase the smell). You could also use soap recipes based on other types of oil, such as coconut oil, which has very little odor.

3. Allowing the Soap to Cure
It's not that the soap would be unsafe if you used it a little earlier than 6 weeks, but it will dissolve fast, and it won't lather well. I've always been disappointed with the quality of the soap anytime that I've tried using it early instead of letting it cure for 6 weeks. It just lacks a richness and quality that is gained with age.

We hope to have more soapmaking videos in the future. In the meantime, you may also want to look at some of the new on-campus soap making courses that we'll be having in 2014.

4. Using an Immersion Blender
No, bubbles aren't going to ruin your soap. Hot process soap should saponify without needing the vigorous stirring that you would use when making cold process soap, so it shouldn't really be necessary to use an immersion blender on a batch of cooked soap.

Let us know if you have more questions. -- Robin

The video is very instructional and helpful. I was wondering how I can go about purchasing the 14x20 wooden mold and the long blade for cutting soap. Also, the only lye I can find is "Draino" from the store. Will this lye work as well? Thank you for your help.

I'm glad you're finding the video helpful. We do have both the soap molds and the long blade for cutting soap available through our Gift Shop, "The Barn." The number there is: 254-754-9643.

You'll need to use pure Sodium Hydroxide (lye) for soapmaking. Draino would not be good to use because it contains other ingredients that could be harmful. You can order Sodium Hydroxide online from www.essentialdepot.com.
