This program calculates the amount of each component based on the mixing ratio of each component when manufacturing violin varnish.
Summary
This program calculates the blending amount based on the blending ratio of each ingredient when manufacturing violin varnish.
In the manufacture of varnishes (alcoholic varnishes), several resins are mixed in given proportions and dissolved in alcohol. However, if you decide the total amount (weight) of the final product including alcohol and want to manufacture only the total amount, it is inconvenient to calculate the amount (weight) of each component one by one to match the total amount. For example, when manufacturing 235 [g] in the same proportion as in Table 1, it is quite cumbersome to calculate how much each component should be added. This program automatically calculates the required amount of each component by inputting the ratio of each component, the amount of alcohol, and the total amount of the final product, so there is no such inconvenience.

Table. 1There are many luthiers who make and use a large amount of varnish at one time, but there is a risk of quality problems with old varnish. Also, if you use different recipes for different instruments, it might be a good idea to make just one instrument's varnish and use it right away. This program was developed for that purpose.
Usage
This program is basically designed for the production of alcohol-based varnishes, but in the case of oil varnishes, mixed varnishes and undercoats, you can calculate by substituting the solvent (oil, turpentine or water) used for the coating instead of alcohol.
Install
Since this program is a portable version, no installation work is required.
After unpacking, double-click the 《Varnish_Calculator_v.X.X.X》 file in the 《Varnish_Calculator_v.X.X.X.exe》 folder to run the program immediately. However, it may take a long time to run depending on the specifications of your computer.
