Should I do a sodium carb wash or just reX?

I have some spice that is orangish in color, not yellow at all, it shimmers in the light but I feel like there have to be impurities in it, which one of these two methods do you thing would be better for about 1g of it.
 
Dissolve your spice in solvent, wash with 20ml of saturated sodium carbonate solution, then evap a little and freeze precip. The reason for this is NaOH isn't very soluble in naptha etc.
 
How much naphtha should I use? I would prefer if my orange/tan dmt would turn white. How much sodium carbonate should I use then? for 40ml of water.
 
If you have 1g spice it should dissolve in 30ml or so of naptha. You may want to use a bit more to make it easier to handle.

This is from Vovins tek:

Step 7: Washing
Naphtha
Distilled Water
Sodium Carbonate

This is a somewhat new process that is not found in many of the older tek's. This process will try to remove as many of the foreign chemicals from the naphtha solution as possible. Especially the lye that was added in a previous step. The goal here is to leave only the DMT in the naphtha so that when you evaporate you end up with pure crystals.

Begin by taking about 50 ml of Distilled water and placing it into a flask and adding sodium carbonate to it. Just add a pinch to the water. It doesn't take much. You will only be using this mixture for the first wash. Do not use it for the second and third washes.

A little dab will do yah here, add only a small amount of the water/sodium carbonate solution to your naphtha. If you have 300 ml of naphtha then you want to put around 25 ml of the sodium carbonated water. Mix the 2 together and then place them in a seperatory funnel. Shake the hell out of it this is the only mixing step where the liquids separate almost immediately so no worries about too much agitation. Separate the water from the naphtha and discard the water.

For the second and third washes you want to use only distilled water nothing should be added. 25 ml per wash is sufficient. Perform the same procedure as above. You should not leave the water in the naphtha for too long. This means no sitting for hours letting it 'soak' you need to get it in and out.
