Note that if you’re using additives, you can get away with a bit more stripchip/pot.
Since I’m using 2x endurance chips/250g I was wondering whether the ratio of wax to stripchip recommendation (6 chips/500g of wax so ~83g of wax / stripchip) applies to the total so I asked the Silca support. The reply I got was that indeed the total wax amount should be considered in the stripchip max ratio, with the recommended ratio is around 100g/chip.
That’s for 250g + 2x72g endurance chips = 394g wax so that’s good for about 4 stripchips.
When I did my fifth I simply added another 100g of wax (reducing the endurance chip ratio).
