    771. Create all the blend ingredient chemicals in the usual manner. Introduce them if necessary.
     8
    892. In the Chemical main menu, select ''Blend ingredients'' and click ''Add Blend Ingredient''
     10
    9113. You will see two drop-down lists labelled ''Chemical'' and ''Ingredient''. This is where you select the blend chemical and one of the ingredients. Enter the precise proportion of the ingredient within the blend.
    10 4. Click [Save] and repeat until the blend is ready for use.
     12
     134. Click [Save] and repeat until the blend is ready for use
    1114
    1215Note 1. If you haven't already created a blend chemical, click the green + plus-sign and give it a name which makes it obviously a blend. You will have to enter the first few initial mandatory fields but nothing is significant because the software just uses it as a vehicle with a blend name to carry other ingredient (real) chemicals. Don't forget to [Save].
     
    1417=== Using a blend
    1518
    16 5. In the Chemical menu select ''Product-chemical proportions '' and click ''Add Product-chemical proportions''
    17 6. In the upper''Product'' drop-down list select the product which will contain the blend
     195. In the Chemical menu select ''Product-chemical proportions '' and click ''Add''
     20
     216. In the upper''Product'' drop-down list select the Product which will contain the blend
     22
    18237. In the lower ''Chemical'' drop-down list select the prepared blend chemical
    19 8. Enter the proportion of the blend in the product and click [Save] twice. First to get the blend saved in the database and secondly to attach all the prepared blend ingredients to the product and process ingredient proportions according to the blend proportion.
    2024
    21 Note 2. Blend proportion is also used to adjust ''Max end-use concentration'' of each chemical.
     258. Enter the proportion of the blend in the Product and click [Save and continue editing] twice.
    2226
    23 Note 3. You can add multiple prepared blends to a product. If the same chemical appears in more than one blend, it only gets added to the product once. Proportions and max concentrations are summed.
     27Note 2. First save in step 8 above gets the blend saved in the database. The second one attaches all the prepared blend ingredients (step 3 repeated above) to the Product and finally calculates Product ingredient proportions according to the blend proportion and the proportions set in step 3 above.
    2428
    25 Note 4. You can manually increase a blend chemical proportions and that will be respected. If the summed blend chemical proportions are less than the existing proportion, the software assumes a human adjusted it upwards.
     29Note 3. Blend proportion in the Product is also used to adjust ''Max end-use concentration'' of each blend chemical ingredient in the Product.
    2630
    27 Note 5. You cannot decrease a blend proportion (or summed proportion) calculated for an ingredient because it will be overwritten by the software to reflect its truth.
     31Note 4. You can add multiple prepared blends to a Product. If the same chemical appears in more than one blend, it only gets added to the Product once. Proportions and max concentrations are summed.
    2832
    29 Note 6. You can optionally delete ''Product-chemical proportions'' blend records after their ingredients have been added. You can also leave them there for the record because they have no further effect beyond confirming calculations on each save. Deleting a ''Product-chemical proportions'' record does not delete either the Product or the Chemical.
     33Note 5. You can manually increase a Product (blend) ingredient proportion and that will be respected. If a summed (blend) ingredient proportion is less than the existing Product ingredient proportion, the software assumes a human adjusted it upwards and doesn't touch it.
     34
     35Note 6. You cannot decrease a Product (blend) ingredient proportion (or summed proportion) because it will be overwritten by the software when recalculating on saving.
     36
     37Note 7. If you must decrease a blend chemical proportion in the Product, the blend recalculation can only be defeated by deleting all ''Product-chemical proportions'' blend records containing that ingredient.
     38
     39Note 8. You can optionally delete ''Product-chemical proportions'' blend records after their ingredients have been added. You can also leave them there for the record because they have no further effect beyond confirming calculations on each save. Deleting a ''Product-chemical proportions'' record does not delete either the Product or the Chemical.
