That is half the fun, experimenting! But sadly sometimes there are just tried and true ways of doing things. But that doesn't mean we can't try new things of course!
My round bath bombs.... Ummmmm we won't go there because they look terrible..... I just don't spend enough time working on mastering the skill.
But I found round flat puck type ones are super simple!
Here are two pictures to show what I mean.
I used a silicone muffin pan mold to make these.... The silicone is flexible so it makes it easy to remove them. Once you use fragrance oil in them you don't want to use them for food again. If you look at thrift stores or often times garage sales you can find lots of silicone bakewear to use for crafting!
To make them all the same I did use a scale to weigh out the amount of bath bomb mixture so they stayed the same weight. I used 4 oz or rather 115 grams because I like using grams to weigh things out because it's a bit more accurate. The bigger the better in my opinion. When I make them for myself, friends or family I do make them larger..... Just remember all that goodness is going to be diluted in how many gallons of bath water.....
But I weighed out my mixture to put into the bomb, and I did use nitrile gloves to make these as well. They are the blue kind like doctors wear. I buy them in a 100 count box in the first aid section of a store. But they have 1,001 uses around the home as well. Seriously! Even the hubby uses them for his own man cave... (he reloads bullets for hunting) but also when he grills meat... That way he can put meat on the grill without contaminating anything else or having to run in and wash his hands right away. They are awesome for deep cleaning as well when your scrubbing...
But I put some of the bomb mixture into the mold and then tap it down with with a tool that I have. But you can use anything that is flat that fits into the mold. It doesn't have to fit all the way across as you can move it around so you get all the sides tapped down. The idea is to compact it as much as you can. The firmer it's compacted the longer it will take to fizz out in the tub. If you have a chunk of closet rod doweling that is 1.5" to 2" that works like a dream! My other secret is to use a hammer and yep it's a great stress relieving tool.... tap the top of the tool down with your hammer to compact them as much as you can.
I let them sit in the mold overnight, but.... in a pinch I throw the mold in the oven on a cookie sheet lined with foil on the lowest setting for about 15-20 minutes. That helps to dry them out.
I know your just making for yourself and maybe some gifts so I want to share another source for fragrances. I buy a couple from this company as they really are just a small mom and pop type business. I need to get an order placed tonight for sandalwood and a few others or I'm going to be in trouble!
This is the page to the descriptions of their scents. http://www.thecandlesource.com/id1.html
Their site is a tad confusing because you add your shipping into your cart based on your order. To find the shipping page, go to online catalog and click shipping options.
It's not in order by price so scroll down to find the one you want.
You can get Four 1 oz bottles for $3.99 shipping
For $6.05 shipping you can get...
Up To 30 - 1 Oz. Bottles
Up To 8 - 4 Oz. Bottles
Up To 4 - 8 Oz. Bottles
I have gotten a mix of 8, 4 oz and 1 oz bottles with this option as I like to sample some of their scents. I just email them to ask them what's okay to ship for that option.
The part I dislike about this site is finding the scents in the size you want. It's not very user friendly as they have all the sizes on different pages and each scent for every size..... It's a bit of a pain, but the prices are worth it. They do have some really nice scents and their prices just can't be beat.
So I thought since you are just making for yourself and family you might enjoy the price break as fragrances can be expensive especially if your ordering less than a pound. I hate to admit that I have a LOT of 1 or 2 oz bottles from various suppliers that I buy from.... and I mean a lot, maybe around 100 or more... And add on another 100 or so that I bought larger bottles of but not all those scents are part of my regular inventory as I don't want to overwhelm my customers.
