Puede frasearse de otra manera ya que es una solución de un éster, pero es siempre un tópico.

It appears you might be referring to a mixture or recipe involving tannic acid and glycerin for creating a paint or staining solution. Tannic acid is a compound commonly found in plants and is often used for its astringent and staining properties. Glycerin, on the other hand, is a colorless and odorless liquid that is used for various purposes, including in cosmetics and pharmaceuticals.

If you're looking to create a paint or staining solution using tannic acid and glycerin, I can provide you with a general idea of how this might be done. However, please note that without more specific details, the exact recipe or process may vary. Always ensure that you are using materials safely and responsibly.

Here's a basic outline of how you might go about creating such a mixture:

**Ingredients:**
- Tannic acid powder or solution
- Glycerin
- Pigment (if you want to add color to the paint)
- Water (if needed)

**Steps:**
1. **Measure Ingredients:** Determine the quantity of paint you want to create and measure out the appropriate amounts of tannic acid and glycerin. The ratio between these two ingredients will depend on the desired consistency and effect of the paint.

2. **Mix Tannic Acid and Glycerin:** In a container, combine the tannic acid and glycerin. Stir or shake the mixture to ensure they are thoroughly mixed.

3. **Add Pigment (Optional):** If you want to add color to your paint, you can mix in a suitable pigment. This could be powdered pigments or liquid colorants. Adjust the amount based on the intensity of color you desire.

4. **Adjust Consistency:** Depending on the desired consistency of the paint, you can add water to thin it out if needed. Mix well to achieve the desired thickness.

5. **Test and Adjust:** Before using the paint on your desired surface, it's a good idea to do a small test to ensure it meets your expectations. If necessary, you can adjust the ratios of tannic acid, glycerin, pigment, and water until you achieve the desired effect.

Remember that this is a general guideline, and the specific proportions and steps might vary depending on your goals. Additionally, some experimentation might be necessary to fine-tune the paint mixture to your liking. If you're working on a specific project, it's a good idea to consult with experts in the field of paints, pigments, or art to ensure you're using safe and effective materials and methods.
