Welcome!
I second Soaping101 videos as an excellent resource. Start with her oldest videos since she builds on the basics from there. Soap Queen also has some good beginner safety videos. There are a ton of videos out there. Some folks do not exhibit safe practices... though they make artistic designs.
My tips from a newbie (me) from the best resource I've found: the folks here
1. Wear safety goggles (eyeglasses do not count)
2. Wear gloves
3. Do not inhale lye fumes. Mix somewhere well ventilated. Remove kids/pets. Do not leave lye water unattended.
4. Soaping containers shouldn't be reused for food
5. Fragrance oil can eat through plastic cups (don't ask me how I know that)
6. Lye Water only belongs in stainless steel or plastic (I use #5 painters' buckets I got from a hardware store). Do not use Pyrex. It gets HOT.
7. If you get lye on you, rinse with a lot of water (not vinegar).
8. Always run recipes through a
lye calculator (soapcalc is great). Even books or recipes that you see here might have typos
9. Weigh everything - preferably in grams for accuracy
10. Don't assume a batch is ruined. Check here first. Much smarter folks than myself can advise on how to save things.
11. Never use anything with aluminum. That includes spoons and hangers...
12. Be prepared to gain an addiction!
