I'm feeling a little confused I bought a mini scale to weigh out very small amounts like ml for making perfumes and I thought why not weigh out my colorants for soap making. I usually use the standard tsp of colorants per pound of soap measuring it with a tsp. Well I thought why not weigh out my tsp of colorants to 5 ml. Well when I dumped a tsp of colorants on the scale it said almost 3 ml it was short by half the tsp. Shouldn't my tsp of colorants weigh 5 ml. Which means almost 2 tsp of colorant is weighing out to be 5 ml which is way to much colorant. I feel puzzled shouldn't 1 tsp of colorant equal 5 ml. Thanks much.

I am confused; why do you believe that a tsp of a specific dry substance (in this case, mica) must equal 5ml?

Also, you seem to be confusing volume measurements (ml) with weight (which would be g or mg).

Thank you yes I'm very bad with math and still trying to figure out volume and weight ha ha I think I'm starting to get it. So would I weigh my mica in grams or should I just forget about weighing out my colorant and continue using my tsp.
 
A scale would weigh in kg (kilogram), g (grams), oz (ounces). A volume measuring utensil measures in ml, liters, tsp, cup. Check your scale, it should have some sort of indicator to say whether it is reflecting g or oz.

You are correct that a teaspoon would almost equal 5 ml, but these measurements are volumes, not weights. Think of volume as how much space it takes and weight as how heavy it is. A scale measures weight, not space.

If your usage of colorant in volumes (tsp or ml) works well for you, no need to change. A teaspoon of one colorant is not necessarily going to weigh the same as another colorant.

Hope this helps.
 
I found this info online I think I understand now. I was still feeling confused last night about it because my small scale weighs ml and I was thinking well how does my scale weigh volume so I asked google how this was possible lol. It told me it goes by the weight of water so it won't work on all ingredients unless they weigh the same as water so this makes more sense to me. I'm feeling a little brighter this morning LoL 😂

I have been thinking of converting to weights also. Using teaspoon measurements and breaking down percentages of a recipe for each color makes it all very confusing. Weights would be so much easier.
Ya! I thought it might be good to weigh it out so I can stretch out my colors and make them last longer I also have noticed some colors I only need 3/4 of a tsp. I'm trying to learn to use less color so my soaps don't leave color in the lather or on the sink or shower.😄

I generally use too little color as I am also trying to avoid leaving color behind. Most of my soaps are pretty light.

I'm the opposite, it's too late after I've blobbed it in. Some colours I think that are dark and will leave colour don't and some colours I think are right leave colour, hit and miss here unless I measure which I don't, it is what it is.
