Materials:

4 kg (9 lb) suet (tallow)

350 g (12 oz) lye

750 ml (3 C) water

500 ml (2 C) lemon juice

7.5 ml (.25 oz) fragrance

gloves

wooden spoon

ventilated work area

molds/glass baking dishes

1. if you are using a pure fat, such as coconut oil or olive oil, you can skip to step 5. Coconut oil yields a soft, quick-lathering soap. Olive oil and other vegetable cooking oils yield a soft soap that never completely hardens.

2. Render the tallow by cutting it into chunks, placing it into the large pot, covering it, and heating on medium heat until it is melted. Stir occassionally.

3. Cool the fat to below the boiling point of water. Add a volume of water equal to that of the fat. Bring the mixture to a boil. Cover and remove from heat. Let sit overnight.

4.Remove the fat from the pot. Discard non-fat gunk (scrape it off of the bottom of the fat) and any liquid.

5. Measure 2.75 kg rendered fat. Cut the fat into tennis-ball size chunks and place the pieces into a large bowl.

6. Set up all of your materials. Ventilate the area (or work outside), put on safety gear, and open all containers.

7. Now Make soap = Pour the water into a large glass or ceramic bowl (not metal). Carefully pour the lye into the bowl and mix the water and lye with the wooden spoon.

8.The reaction between water and lye gives off heat (is exothermic) and vapors that you should avoid breathing. The spoon will be somewhat degraded by the lye.

9.Once the lye is dissolved by the water, start adding the chunks of fat, a bit at a time. Keep stirring until the fat is melted. If necessary, add heat (put on a low burner with ventilation).

10. Stir in the lemon juice and fragrance oil (optional). Once the soap is well-mixed, pour it into molds. If you use glass baking dishes for molds, you can cut the soap into bars after it has become firmer (not hard).

11. The soap will harden in approximately an hour.

12. You may wrap the finished soap in clean cotton rags. It can be stored for 3-6 months in a cool, well-ventilated location.

13.Wear gloves when washing your equipment, as their may be some unreacted lye remaining. Wash in very hot water to help melt away the residue.

Here`s the bottle cleaner formula, you can make it easily

Soda Ash = 20 gr

Trisodium Phosphate = 25 gr

Sodium Metasillicate = 10 gr

mix all, and ready to use

a blue solution gradually becomes clear. When the flask of liquid is swirled around, the solution becomes blue again.

materials tha needed

1. tap water

2. two 1-liter Erlenmeyer flasks, with stoppers

3. 7.5 g glucose (2.5 g for one flask; 5 g for the other flask)

4. 7.5 g sodium hydroxide NaOH (2.5 g for one flask; 5 g for the other flask)

5. 0.1% solution of methylene blue (1 ml for each flask)

Procedure

1. Half-fill two one-liter Erlenmeyer flasks with tap water.

2. Dissolve 2.5 g of glucose in one of the flask (flask A) and 5 g of glucose in the other flask (flask B).

3. Dissolve 2.5 g of sodium hydroxide (NaOH) in flask A and 5 g of NaOH in flask B.

4. Add ~1 ml of 0.1% methylene blue to each flask.

5. Stopper the flasks and shake them to dissolve the dye. The resulting solution will be blue.

6. Set the flasks aside (this is a good time to explain the chemistry of the demonstration). The liquid will gradually become colorless as glucose is oxidized by the dissolved dioxygen. The effect of concentration on reaction rate should be obvious. The flask with twice the concentration uses the dissolved oxygen in about half the time as the other solution. A thin blue boundary can be expected to remain at the solution-air interface, since oxygen remains available via diffusion.

7. The blue color of the solutions can be restored by swirling or shaking the contents of the flask.

8. The reaction can be repeated several times.

9. Safety & Clean-Up

Avoid skin contact with the solutions, which contain caustic chemicals. The reaction neutralizes the solution, which can be disposed of by pouring it down the drain.

How the Blue Bottle Reaction Works

In this reaction, glucose (an aldehyde) in an alkaline solution is slowly oxidized by dioxygen to form gluconic acid:

CH2OH–CHOH–CHOH–CHOH–CHOH–CHO + 1/2 O2 --> CH2OH–CHOH–CHOH–CHOH–CHOH–COOH

Gluconic acid is converted to sodium gluconate in the presence of sodium hydroxide. Methylene blue speeds up this reaction by acting as an oxygen transfer agent. By oxidizing glucose, methylene blue is itself reduced (forming leucomethylene blue), and becomes colorless.

If there is a sufficient available oxygen (from air), leucomethylene blue is re-oxidized and the blue color of solution can be restored. Upon standing, glucose reduces the methylene blue dye and the color of the solution disappears. In dilute solutions the reaction takes place at 40-60°C, or at room temperature (described here) for more concentrated solutions.

In addition to the blue -> clear -> blue of the methylene blue reaction, other indicators may be used for different color-change reactions. For example, resazurin (7-hydroxy-3H-phenoxazin-3-one-10-oxide, sodium salt) produces a red -> clear -> red reaction when substituted for methylene blue in the demonstration. The indigo carmine reaction is even more eye-catching, with its green -> red/yellow -> green color change.

How to Perform the Indigo Carmine Color Change Reaction

1. Prepare a 750 ml aqueous solution with 15 g glucose (solution A) and a 250 ml aqueous solution with 7.5 g sodium hydroxide (solution B).

2. Warm solution A to body temperature (~98-100°F). Warming the solution is important.

3. Add a 'pinch' of indigo carmine, the disodium salt of indigo-5,5’-disulphonic acid, to solution A. You want a quantity sufficient to make solution A visibly blue.

4. Pour solution B into solution A. This will change the color from blue -> green. Over time, this color will change from green -> red/golden yellow.

5. Pour this solution into an empty beaker, from a height of ~60 cm. Vigorous pouring from a height is essential in order to dissolve dioxygen from the air into the solution. This should return the color to green.

6. Once again, the color will return to red/golden yellow. The demonstration may be repeated several times.
